Few scents can outdo that of a dwarf gardenia. Dwarf gardenias, like their regular sized siblings, are evergreen shrubs with ethereal creamy, white flowers. They need full to partial sun for best bloom in rich, well-draining soil. Miniature gardenia plants are a bit fussy about their care, especially when young. Learn how to grow dwarf gardenia and you will soon be enjoying their intoxicating fragrance.

How to Grow Dwarf Gardenia

Miniature gardenia plants have the same care and site requirements of the larger varieties. Gardenias are native to tropical and sub-tropical regions, and as such have little frost tolerance and perform best in hot weather. Following expert tips on growing dwarf gardenias can help avoid common mistakes that can compromise plant health or blooming.

Good gardenia care starts with proper installation and site. These shrubs prefer acidic soil with a pH between 5.0 and 6.0. The soil should be amended with plenty of organic items and checked for drainage. If drainage is minimal, incorporate some gritty matter to the soil. Gardenias like moist soil but it should not be boggy.

When planting, make sure the hole is wide and deep enough to spread the root system out. Fill in around roots carefully and water immediately to settle soil. Gardenias need one inch (2.5 cm.) of water weekly.

Growing Dwarf Gardenias in Pots

Gardenias need temperatures of 65 to 70 degrees F. (18-21 C.) during the day to produce flowers and night temperatures of 60 to 65 degrees F. (15-18 C.). For this reason, many gardeners choose to grow gardenias in pots.

Provided the soil mixture has rich loam and some peat moss mixed, it will be nutrient rich, acidic, and well-draining enough for the plant. Place containers on casters so you can easily move them in and out with the seasons.

Containerized plants will need fertilizing in spring every two weeks but suspend feeding by the end of summer. They will also require more water than in-ground plants but keep them slightly drier in winter.

Place containers where the light is bright but indirect and there are no drafts. Provide humidity by misting daily or placing a dish of water near the plant.

General Dwarf Gardenia Care

A nice organic mulch spread around the root zone will prevent weeds and help keep roots cool and soil moist.

Prune spent blooms as they occur to promote continuous flowering. Take flowers off just below the leaf node. Prune the plant during the dormant season to keep the gardenia in a tidy habit. Remove any crowded or crossed stems at this time to increase air circulation and light to the center of the plant. This will discourage fungal diseases and encourage blooming.

Feed in-ground plants with an acidic fertilizer after bloom or use a granular time release formula at the beginning of the season.

Once established, dwarf gardenia care is minimal and the shrubs will faithfully produce those heavenly scented flowers year after year.

Gardenias are known for their beauty and fragrance. An elegant specimen, the gardenia is often used as the primary flower in a corsage. Unfortunately, as with many beauties, these plants are sometimes challenging to grow. Soil and sunlight must be just right for the fickle specimen to flourish in the garden or a container. Good news, though, the grafted everblooming gardenia (Gardenia jasminoides "Veitchii") is more reliable. While it benefits from proper care, this plant is more flexible on soil and nutrient needs. Those who haven’t been successful growing gardenias might want to give this one a try.

About Everblooming Gardenias

You are probably wondering, just what is an everblooming gardenia? This plant is grafted and blooms throughout spring and summer, sometimes even into autumn. Possessing the best traits of the traditional gardenia without some of the difficulty, your dreams of beauty and fragrance in the garden are fulfilled. The plant is grafted onto a sturdy, nematode-resistant rootstock that grows well, even in poor soil. Gardenia thunbergii rootstock is better able to uptake nutrients from the soil than the traditional gardenia rootstock. The mature everblooming grafted gardenia grows to a height of 2 to 4 feet (.61 to 1.2 m.), spreading up to 3 feet (.91 m.) across. The everblooming species, also known as Gardenia veitchii, has a mounding habit and a sweet fragrance. Grow it in pots near doorways and on patios to enjoy the wonderful fragrance.

Growing Grafted Everblooming Gardenia

Hardy in USDA zones 8 through 11, plant the everblooming gardenia where it grows in full to partial sunlight. In more northern areas, grow grafted gardenia in a pot so you can provide it with winter protection from the cold. Gardeners in zone 7 may find a microclimate where this specimen can overwinter outside when mulched. With proper conditions and ongoing care, Gardenia veitchii continues indoors as a houseplant. Plant in acidic, well-draining soil for the most prolific blooms. Prepare the soil with well-rotted compost and pine fines before planting everblooming grafted gardenia. If soil is clay, compacted, or both, add additional compost, elemental sulfur and iron sulfate. A soil test of the planting area lets you know how much is needed. The optimum soil pH of between 5.0 and 6.5 is necessary for the plant to thrive. Fertilize with a food for acid-loving plants in mid-spring and again in mid-summer. This specimen also grows well in large containers that allow it to reach full growth. Water regularly, keeping the soil evenly moist. Problems with mealybugs, aphids, and powdery mildew may affect the plant. Keep a close eye out for these issues and treat with horticultural soap or neem oil, if needed.

With their deep green leaves and waxy white blooms, gardenias are a beloved garden staple in mild climates, especially in the southern United States. These hardy plants tolerate heat and humidity, but they can be tricky to grow, especially in cooler climates. Read on to learn about troubleshooting gardenia leaf curl.

Help! My Gardenia’s Leaves are Curling!

If leaves of gardenia are crinkling and wrinkling, there may be several factors at play.

Gardenia Leaf Curl and Spider Mites

Spider mites are often to blame when leaves of gardenia are crinkling. You may not notice the pests because they’re so tiny, but the fine webbing they leave on the foliage is a telltale sign. A gardenia affected by spider mites may also exhibit yellow or spotted leaves. If you decide spider mites are causing gardenia leaf curl, you can often remove the eggs and mites with a strong stream of water from a garden hose. If that doesn’t work, use a commercial insecticidal soap spray. You may need to spray every few days until the pests are eradicated. If all else fails, try a systemic insecticide that will be absorbed throughout the plant. Also, be sure to water properly; mites are attracted to dry, dusty conditions.

Curly Gardenia Leaves due to Soil Problems

Gardenias prefer acidic soils with a pH between 5.0 and 6.5. It’s a good idea to test the soil before planting gardenias and to make adjustments if the pH level is too high. If you’ve already planted gardenias without testing the soil, make adjustments by adding chelated iron, aluminum sulfate, or water-soluble sulfur to the soil about 3 feet (1 m.) from the plant. You can also spray the leaves with chelated iron. Once the plant is looking healthier, feed it regularly, using a slow-release fertilizer for acid-loving plants such as azalea or rhododendron. Continue to test the soil regularly and make adjustments as needed.

Wrinkled Garden Leaves from Improper Watering

Improper watering, either too much or too little, may contribute to a problem with curly gardenia leaves. Gardenias need regular, consistent irrigation, but the soil should never become too wet or too dry. As a general rule, gardenias need at least 1 inch (2.5 cm.) of water per week, either from irrigation or rainfall. A generous layer of mulch will prevent evaporation and help keep the soil evenly moist.

Gardenias are beautiful, fragrant, flowering shrubs that are especially popular among gardeners in the southern United States. Although they are very attractive, they can be somewhat high maintenance to grow, particularly because they can be susceptible to several serious diseases. One such disease is stem canker. Keep reading to learn more about canker and galls on gardenia stems.

What is Stem Canker of Gardenia?

Stem canker of gardenia is a problem caused by the fungus Phomopsis gardeniae. The cankers themselves begin as dark brown, oval shaped spots that run longitudinally (perpendicular with the ground) along the stem of the plant. Sometimes, these spots are sunken with a sharp edge. With time, the spots harden and crack open. On occasion, they form into galls, swollen areas on the stem. Gardenia stem galls are also symptoms of the Phomopsis fungus that develop when there are several cankers in the same spot. Gardenia stem canker and galls tend to appear at the base of the plant’s stem, near the soil line. The stem directly above the cankers and galls might change color from its usual light green to bright yellow. It’s also possible for these symptoms to be found on the plant’s leaves and roots. Canker and galls on gardenia stems cause the plant to become stunted and eventually die.

How to Treat Gardenia Stem Canker and Galls

The Phomopsis fungus enters gardenia plants through wounds in the tissue. Due to this, the best way to prevent gardenia stem galls and canker is to avoid damaging the plant. If any part of the plant becomes damaged, prune it away. Avoid stressing the plant by maintaining a steady water and feeding regimen. If a plant becomes infected, remove and destroy it. The fungus spreads through humidity and moisture and can survive the cold of winter inside the plant. Plant new gardenias in a different location.

Gardenias are a favorite of gardeners in warm climates, who understandably love the plant for its glossy green leaves and sweet smelling white flowers. However, this exotic plant can be somewhat finicky and it can be difficult to determine the reason when a gardenia plant is not blooming. If your gardenia won’t flower, there are several possible factors that may be to blame. Read on to learn about the most common reasons when there are no blooms on gardenias.

My Gardenia Won’t Flower

Troubleshooting when there are no flowers on gardenia plants is often necessary in order to pinpoint the best possible reason. Improper pruning– When a gardenia plant is not blooming, the reason is often pruning too late in the season. Prune gardenia plants after flowering in summer, but before the plant has time to set new buds. Pruning too late in the season will remove buds in the process of developing for the next season. Keep in mind that some cultivars flower twice during the season. Bud drop– If buds are developing and then falling off the plant before flowering, the problem is likely environmental. Be sure the plant gets sunlight, preferably in the morning with shade during the heat of the afternoon. Gardenias prefer well-drained, acidic soil with a pH of less than 6.0. Soil with an improper pH may be the reason when there are no blooms on gardenias. Extreme weather– Temperature extremes, either too hot or too cold, can also prevent blooming or cause buds to drop. For example, if you want to know to how to get blooms on gardenia, temperatures should be between 65 and 70 degrees F. (18-21 C.) during the day and between 60 and 63 degrees F. (15-17 C.) during the night. Lack of nutrition– Feed gardenias lightly in early spring after all danger of frost has passed using a fertilizer formulated for gardenias, rhododendrons, azaleas, and other acid-loving plants. Repeat in about six weeks to ensure the plant has adequate nutrition to support continued blooming. Pests– A severe insect infestation may be to blame when a gardenia won’t flower. Gardenias are susceptible to attacks by spider mites, aphids, scale, and mealybugs; all of which are usually easily controlled by regular applications of insecticidal soap spray.

Many southern gardeners fall in love with the sweet fragrance of gardenia blooms. These beautiful, fragrant, white flowers last for several weeks. Eventually, though, they will wilt and turn brown, leaving you wondering “should I deadhead gardenias?” Continue reading to learn why and how to deadhead a gardenia bush.

About Deadheading Gardenias

Gardenias are flowering evergreen shrubs hardy in zones 7 to 11. Their long lasting, fragrant white flowers bloom from late spring to fall. Each bloom can last several weeks before wilting. The wilted flowers then form into orange seed pods. Removing spent blooms on gardenia will prevent the plant from wasting energy producing these seed pods and put that energy into creating new blooms instead. Deadheading gardenias will also keep the plant looking nicer throughout the growing season.

How to Deadhead a Gardenia Bush

When to deadhead gardenia flowers is right after the blooms fade and begin to wilt. This can be done anytime throughout the blooming season. With clean, sharp pruners, cut off the entire spent bloom just above a leaf set so you are not leaving odd-looking bare stems. Deadheading like this will also promote the stems to branch out, creating a thicker, fuller shrub. Stop deadheading gardenias in late summer to early fall. At this point, you can leave the spent flowers on the shrub to form the orange seed pods that will provide winter interest. These seeds also provide food for birds in fall and winter. You can also prune back your gardenia bush in fall to keep it compact or promote denser growth the following year. Do not prune back gardenias in spring, as this may cut off newly forming flower buds.

Gardenias are gorgeous plants, valued for their big, fragrant blooms and glossy, deep green foliage. They have a reputation for being slightly fussy, but the exquisite beauty and heavenly aroma are worth the extra effort. Choosing gardenia plant companions can be tricky as well. The best companion plants for gardenias are those that share the same growing conditions without detracting from showy gardenia plants that deserve to take center stage in the garden.

Choosing Suitable Gardenia Plant Companions

Gardenia thrives in partial shade, preferring morning sunlight with shade during sunny afternoons. The best gardenia plant companions are other plants that tolerate conditions that are less than sunny. Gardenias also prefer moist, well-drained, acidic soil, so select gardenia plant companions accordingly. Select plants that won’t compete with gardenia’s root zone and allow adequate spacing to prevent crowding. As a general rule, plants with relatively shallow roots are good gardenia plant companions. Avoid heavily scented plants that may compete or masque the intoxicating aroma of gardenias. Annuals are always good companion plants for gardenias but be careful that the colors don’t “fight” with their creamy white blooms. Also, bear in mind that most gardenia plants grow in USDA plant hardiness zones 9 and 10, although some newer hybrid gardenias tolerate the cooler temperatures of zone 8. When considering companion plants for gardenias, select plants that are happy within those zones.

What to Plant with Gardenias

Here are a few suggestions for gardenia companion planting. Blooming annuals

• Wax begonia
• Impatiens
• Primrose

Perennials for partial shade

• Hosta
• Ferns
• Strawberry begonia (Saxifraga)

Shrubs

• Rhododendrons and azalea (prefer acidic soil)
• Boxwood
• Camellia
• Summersweet (Clethra)
• Virginia sweetspire

Gardenias are fairly hardy plants suitable for USDA zones 8 to 10. They can handle light freezes, but the foliage will get damaged with sustained cold in exposed locations. The extent of cold injury of gardenias is never certain until spring when new shoots and leaves appear. Sometimes the plant recovers and very little tissue is lost. Occasionally, a very hard hit gardenia will lose the battle if the root zone was deeply frozen and winter dryness was a factor. Frost damage on gardenia is a common complaint, but here are a few tips on how to diagnose and treat the problem.

Symptoms of Gardenia Cold Damage

It is hard to resist the shiny, lustrous leaves and starry scented flowers of a gardenia. Even when you know better, sometimes the intrepid gardener will purchase one even if they are living in a borderline zone. That said, gardenia planted in the appropriate hardiness zones may also experience surprise weather and winters of unusual ferocity. Gardenia cold damage occurs even when there is no snow on the ground. A combination of exposure, dryness, and frost causes the bulk of the damage. If your gardenia got too cold, initial symptoms will be brown or black leaves, and even the stem is sometimes affected. Sometimes the damage will not show up for several days, so it is important to check sensitive plants at a later date for frost damage on gardenia. In spring, damaged leaves will generally crumble and fall off, but woody tissue will need to be assessed. In exposed locations, it is probable a gardenia in cold weather will have some affected tissue but it may not be obvious until spring when budding and leaves fail to recur on stems.

Conditions that Affect Gardenia in Cold Weather

Winter can be drying to plants unless you live in a rainy area. Plants are more susceptible if the root zone is dry, which means giving the plant a deep drink prior to expected frost. Gardenias in exposed locations in full sun benefit from having their leaves sprinkled as the water freezes. This creates a protective cocoon over the tender tissue. Mulches are effective in protecting a gardenia in cold weather but should be pulled away from the base in spring. Plants that are exposed and have no other shielding plants or buildings are susceptible to cold injury of gardenias.

Treating Cold Injury of Gardenias

Whatever you do, don't start hacking off the dead growth in winter. This can cause more harm than good and it isn't apparent the tissue is fully dead at this time. Wait until spring for pruning and see if any of the stems come back to life and start to produce new shoots and buds. If the tissue doesn't revive by then, make clean pruning cuts to remove it back to green wood. Baby the plant that season with supplemental water and good fertilizing practices. Monitor it for the slightest pest or disease, which could fell the gardenia in its weakened state. In most cases, when a gardenia gets too cold, it will recover in spring or within a year or two if the damage is severe.

Gardenias are finicky shrubs that don't perform well unless you meet all of their needs. This article discusses problems that cause brown spots on gardenia buds and flowers, and how to correct them. Read on to fix gardenia flowers with brown spots.

Spots on My Gardenia Buds

First, let's look at three stress factors that cause problems with gardenia flowers. Brown spots may be caused by warm night temperatures, too little sunlight, or too little water. Pests can also be to blame. Temperature - When night temperatures are above 60 degrees F. (15 C.), flowers and buds may drop off or brown. This temporary condition improves when night temperatures cool. Buildings and pavement retain heat and keep the surrounding air warm at night, so plant gardenias in the open areas and away from structures. Light - Gardenias grow well in sun or partial shade. Too much shade causes poor flowering and flowers that brown and drop off prematurely. Shade also encourages fungal infection. Before planting, consider the amount of sunlight the shrub will get in spring and summer when surrounding trees and shrubs are in full leaf. Also, think about the growth patterns of surrounding plants, and whether they will create a shade problem in years to come. Water - Allowing the soil to dry out causes brown spots on gardenia flowers and buds that drop off before they bloom, so keep the soil around the shrub moist at all times. Water the plants regularly but keep the leaves and flowers dry by applying the water directly to the mulch that surrounds the plant. Drip irrigation and soaker hoses are excellent choices for watering gardenias. Water droplets that remain on the plant can also make gardenia flowers turn brown or develop spots. Pests - Mites are a common source of gardenia flower bud problems. Bud mites cause the tips of the buds to turn brown, and the buds fall off before they bloom. You can get rid of bud mites with an insecticide that contains carbaryl, such as Sevin. If you prefer a natural approach to pest control, simply remove all of the buds and keep them picked off for a couple of weeks. Without a food source, the mites will move on.

The brilliant white blooms of the gardenia are only their second best feature - that heavenly smell they produce fills the air with a scent like no other. It's no wonder that gardeners are extremely protective of their gardenias! Unfortunately, even the most pampered plant may develop one of the common gardenia diseases. This handy guide will arm you with the knowledge to properly care for your favorite plant.

Common Diseases of Gardenia

Most common diseases in gardenia plants are caused by fungus, and easily prevented by creating a well-draining environment with good air circulation. Proper watering and pruning further helps to keep gardenia plant diseases in check. Among the most common diseases of gardenia are root rot, powdery mildew, stem canker and bud drop. Treating gardenia problems like these is a task most gardeners can handle.

Root Rot

Root rot is common in plants that are chronically over-watered or are growing in poorly draining soil. A variety of fungal pathogens take advantage of the stressed plant and destroy root tissues, causing them to turn brown, black or mushy. You may notice that your plant is yellowing, with the oldest leaves affected first - it can come on gradually or cause a sudden widespread wilt in your gardenia. You can often save plants with root rot by digging them, pruning away damaged roots and replanting them in a spot with better drainage. Be careful to only water when the top two inches of soil feel dry to the touch to prevent future problems.

Powdery Mildew

Powdery mildew results when air circulation is poor, allowing humidity to build around dense bushes or tree canopies. Unlike other fungal diseases, standing water isn't necessary for powdery mildew spores to germinate, but they can't survive without constantly humid conditions. Powdery mildew causes a distinct white, fuzzy or powdery coating on leaves and deformation of new growth. Neem oil is very effective control, but you should also consider thinning the inside of your gardenia to allow for better air circulation. If your gardenia is potted or indoors, move it away from structures and other plants. Powdery mildew isn't serious, but a chronic case can drain a plant, allowing other pathogens to invade.

Stem Canker

Stem canker only affects a small percentage of gardenias yearly, but it's a serious disease that every grower should be aware of. These dark, oval lesions are caused by the fungus Phomopsis gardeniae when it manages to gain access through wounds. Galls may form on affected branches, but more often, widespread wilt is seen. The plant may stunt or drop leaves and buds, depending on the seriousness of the infection. The only control is to remove the affected stems, cutting back well into healthy tissues. Disinfect your pruners between cuts to prevent spreading the disease further. As with other fungal diseases, increasing drainage, taking more care in watering and increasing air circulation can help prevent recurrence.

Bud Drop

Bud drop appears in stressed gardenias, but can be baffling to gardeners who have never seen it before. As the name implies, the primary symptom is bud and flower failure - they simply drop or dry up, with few other clues. Pests and environmental problems are to blame for this common problem - check your plant carefully for tiny bugs and treat accordingly. Additionally, sooty mold can be seen on plants affected by insect pests, like aphids. Treating the pests will normally take care of the fungus. Neem oil works well for both. If no insects are present, you may need to adjust your watering habits, fertilize more carefully or provide better protection from sudden cold spells.

If you have been successful growing gardenia shrubs outdoors, you may wonder if you can grow gardenia plants inside. The answer is yes; however, there are a few things to learn before you run out and purchase a plant.

Gardenia Houseplants

While there are many indoor plants that require little attention, gardenia houseplants are not this type. One of the most frustrating things about these lovely and fragrant plants is how finicky they are. If you plan on giving a gardenia plant to someone for a gift, be sure that they know how to care for it or they will be terribly disappointed. 

Growing gardenias indoors, within the confines of your home, requires close attention to humidity, light, and pest control. If placed in the correct environment and given proper care, an indoor gardenia will reward you with glossy, green leaves and aromatic flowers.

How to Grow a Gardenia Indoors

Gardenias are native to Japan and China and thrive on the south and west coasts of the United States where they often reach up to 6 feet tall (2 m.). Indoor gardenias require cool temperatures, moderate humidity, and plenty of bright light to thrive. 

When you first bring your gardenia home, it is essential to have the best spot picked out because they do not respond well to being moved around. This spot should have plenty of light, at least half a day of direct sun, and be in a room with a temperature that is about 64 F. (18 C.) during the day and 55 F. (13 C.) at night.

Care of Indoor Gardenia

Once you have found a good place for your gardenia indoors, your next challenge is moderating the humidity. This is especially challenging during the winter when the indoor heat kicks in. The drying nature of most heat can cause a once beautiful gardenia to fall to pieces, literally. 

There are a few ways to increase indoor humidity. The first is to group houseplants close together, the second is to spray a light mist of water on foliage during the early morning hours, and the third is to run a humidifier. Keep your plant free of drafts and never place a gardenia where it will receive the direct force of hot air from a furnace. 

Provide water when the soil is dry to touch and add fertilizer or acid-loving plants during the growing season. Remove woody stems to encourage prolific blooming.

Pests on Gardenia Houseplants

Keep a close eye out for gardenia pests such as aphids, mealybugs, whiteflies, root nematodes, and scale bugs. Aphids are most common and can be treated with a solution of one part liquid soap and one part water. S

pray both the top and the bottom of the leaves. This same soap solution will often treat mealybugs and scale as well. If you suspect your gardenia has spider mites, you can confirm this by shaking the leaves over a white sheet of paper. Fold the paper in half and check for red-smeared spots. 

Treat spider mites with neem oil (Note: This will also work on the previously mentioned pests). Whiteflies are found on the underside of leaves. It is important to remove infected leaves and treat the entire plant with neem oil. Yellowing leaves may indicate root nematodes; unfortunately, there is no cure for this.

They're the aroma of romance and soft summer nights. They're the traditional corsages at proms and the boutonnieres of weddings and funerals. They're the scent of springtime in the south. They're the gardenia. Varieties abound, over 250 of them, but all gardenia types have two things in common: their luscious scent and lovely, waxy, white flowers.

Popular Gardenia Types

All gardenia varieties are members of the genus Gardenia and the coffee family, Rubiaceae. Most types of gardenias in the United States stem from the early Gardenia augusta. Due to their fragrant blossoms and thick, attractive foliage, certain types of gardenia are prized as shrubs for their use as hedges and borders and specimen plantings, particularly near walkways and garden seating areas where their fragrance lingers in the evening. Farther north, where the winters are too harsh for the shrub's survival, varieties of gardenia are grown as container plants, spending their summers outdoors and winters inside. The following are some of the most popularly grown varieties of gardenias in the south:

• August Beauty - With large double flowers up to 3 inches (8 cm.) across, this is one of the most frequently found varieties of gardenia. It flowers in early summer and sporadically into fall. It is a large shrub, growing to 6 feet (2 m.) tall and when not in bloom, its perfect large glossy foliage makes an attractive specimen. It is one of the most cold hardy, growing freely up to USDA plant hardiness zone 7.
• Kleim's Hardy - Another hardy type of gardenia, this one has six single petals to each flower with bright yellow stamens. Its large, shining leaves enhance its rounded growth, which can reach 2 to 3 feet (0.5-1 m.) tall and wide.
• Aimee Yashioka - Commonly called Cape Jasmine or Cape Jessamine, these are old-time gardenias. Varieties are known for their intense fragrance and their gorgeous, ivory-white, double blooms that can reach 4 to 5 inches (10-13 cm.) across. These are the specimens that gave the species its reputation. This is a fast growing cultivar that can reach 12 feet (4 m.) or more and as a bonus, blooms twice during the growing season.
• Radicans - Another garden favorite among the smaller gardenia types. It is slow growing and only reaches 24 to 36 inches (61-91 cm.) in height. The foliage is smaller than many other gardenia varieties and sports 2 to 3 inch (5-8 cm.), single petaled flowers that are creamy white. Like its larger cousins, Radicans is deliciously fragrant and blooms later in the season, which makes it a great partner for some of the earlier blooming cultivars.
• Mystery - This medium-sized shrub is also known to be hardy to zone 8. As with most types of gardenia, this one has dark glossy foliage and a heady fragrance. What makes Mystery different among gardenia varieties is that it produces its double, white blossoms from spring until fall. Fully grown, it reaches about 5 feet (1.5 m.) tall and 3 feet (1 m.) wide, making it suitable for areas where larger varieties would overwhelm. This is a lovely addition to add privacy and fragrance to a small patio.
• First Love - Who could resist such a name? It may very well be your first love among the many varieties of gardenia. It's a compact grower that reaches 5 feet (1.5 m.) high and 3 feet (1 m.) wide and is one of the earliest blooming gardenias in the spring. The double blooms are some of the largest to be found and the showy flowers are wonderful for cutting as well as enjoyment outdoors.

These are just a few of the varieties of gardenias that are available through catalogs and local nursery centers. More cultivars await your discovery. If you live in southern climes, one of these beauties is a must for your garden. With all the varieties available, there's sure to be one that fits your needs.

Gardenias are grown for their large, sweetly fragrant flowers and glossy evergreen foliage. They are meant for warm climates and sustain substantial damage when exposed to temperatures below 15 degrees F. (-9 C.). Most cultivars are hardy only in USDA plant hardiness zones 8 and warmer, but there are some cultivars, labeled as cold-hardy, that can withstand winters in zones 6b and 7.

How to Winterize Gardenia Outside

Be ready for unexpected cold snaps by keeping supplies on hand to protect your plant. On the fringes of the recommended climate zones, you can protect gardenias in winter by covering them with a blanket or cardboard box during brief cold snaps. A cardboard box large enough to cover the shrub without bending the branches is a must when temperatures drop. Gardenia winter care in areas that experience snow includes protecting the branches from the weight of heavy snow accumulation. Cover the plant with a cardboard box to prevent the weight of the snow from breaking the branches. Have old blankets or straw available to insulate the shrub under the box for an extra layer of protection. Outdoor container grown plants can be overwintered in a sheltered location and insulated with bubble wrap in areas just outside their growing zone, or one zone lower. For colder areas, however, these should be brought inside (see care below). Despite your best efforts, the tips of the branches may die and turn black from frost or cold damage. When this happens, prune the branches a couple of inches (5 cm.) below the damage with sharp pruning shears. If possible, wait until after it blooms.

Indoor Winter Care for Gardenias

In colder areas, plant gardenias in containers and provide winter care for gardenias indoors. Clean the plant with a strong spray from a water hose and thoroughly examine the foliage for insect pests before bringing it indoors. When wintering over gardenia plants indoors, keep in mind that these are evergreen shrubs that don't go dormant in winter, so you will need to continue to provide optimal growing conditions. A gardenia kept indoors over winter needs a location near a sunny window where it can receive at least four hours of direct sunlight each day. Indoor air is dry in winter, so you will have to provide extra humidity for the plant during the winter months. Place the plant on top of a tray of pebbles and water or run a small humidifier nearby. Although you should mist the plant occasionally, misting alone doesn't provide enough humidity for good health. Gardenias overwintered indoors need cool night temperatures of around 60 degrees F. (16 C.). The shrub will survive warmer night temperatures but it may not flower well when you take it back outdoors. Keep the soil lightly moist and use a slow-release azalea fertilizer according to the package instructions.

Propagating and pruning gardenias goes hand in hand. If you plan to prune your gardenia, there is no reason why you should not also be starting gardenias from the cuttings so that you can use it in other spots in your yard or to share with friends. Keep reading to learn how to start a gardenia from a cutting.

How to Start a Gardenia from a Cutting

Propagating gardenias from cuttings starts with getting the gardenia cuttings. The cutting should be at least 5 inches (12.5 cm.) long and taken from the tip of the branch. 

Ideally, they will be softwood (green wood). The next step in starting gardenias from cuttings involves removing the lower leaves. Take all the leaves off the cutting except for the top two sets. After this, prepare a pot to root the gardenia cutting in. Fill the pot with equal parts of peat or potting soil and sand. 

Dampen the peat/sand mixture. Dip the cut end of the gardenia cutting into a rooting hormone. Stick your finger in the peat/sand mix to create a hole. Place the gardenia cutting in the hole and then backfill the hole. Place the gardenia cutting in bright but indirect light and keep the temperature around it at about 75 F. (24 C.). Make sure that the peat/sand mixture stays damp but not soaked. 

An important part of propagating gardenias successfully is ensuring that the gardenia cuttings stay in high humidity until they root. There are several ways to do this. One way is to cover the pot with a milk jug with the bottom cut off.

Another way is to cover the pot with a clear plastic bag. Whatever method you use to increase the humidity, do not allow the cover to touch the gardenia cutting. When starting gardenias from cuttings using this method, you can expect that the plant will be rooted in four to eight weeks.

Propagating gardenias from cuttings can make good use of leftover trimmings from pruning. Now that you know how to start a gardenia from a cutting, you will have more than enough gardenia plants for all your friends and family.

Gardenias are beautiful flowers that a lot of people put in their gardens because of their beauty and ability to withstand many soil and temperature differences. They last through the season and will beautify any area around the home. However, they are susceptible to a few gardenia insects and related diseases. Let's take a look at some common gardenia pests and their related problems with gardenias.

Common Gardenia Insects

One of the biggest gardenia leaf pests is the aphid. These can be quite challenging to deal with. These pesky gardenia bugs have soft little bodies and are tear-shaped. They cluster usually below leaves and around new growth on the gardenia plant. The aphids actually suck the fluid from the plant, which is why they like the new growth because it tends to be more lush and moist. Since they are a sucker, these garden insects can spread viruses as well. As far as gardenia insects go, these particular gardenia bugs are quite hard to control. It is best to keep weeds down to a minimum in your flower garden and if you see ladybugs, don't kill them. Ladybugs will eat the aphids. There are some pesticides that will work to control aphids, but you want to be sure not to kill the good bugs with the aphids. Neem oil is a good choice. Another of the gardenia pests is the mealybug. Mealybugs are the most common gardenia leaf pests you will see. They are white and found in masses along the leaves of the gardenia. They tend to hide along protected areas of the plant.

Common Insect Related Gardenia Diseases

Other than gardenia bugs, there are a few other gardenia diseases to consider. One of the worst gardenia diseases is sooty mold. Sooty mold is a foliage disease that turns the leaves of the gardenia black. It doesn't injure the plant, but it does prevent sunlight from getting to the plant via the leaves, so the plant doesn't perform as much photosynthesis. This is bad for the plant and can inhibit growth. Sooty mold thrives on the honeydew created by gardenia bugs like aphids. If you control the aphids, you will also be able to control sooty mold. Keeping these problems with gardenias in check requires constant diligence. Be sure to check your plants frequently and deal with any gardenia pests quickly to reduce the damage they cause.

Flower gardeners have long been lured by the charms of the gardenia plant. The shrubs are most commonly grown in the South in planting beds near homes, patios, or along paths. This allows for passersby to better enjoy their incredible scent, which is usually most prominent late in the evening or at night. Though their flowering period extends throughout spring, it's not uncommon for the plant to bloom sporadically during warmer months as well.

Known for its beautiful foliage and intoxicating fragrance, it's easy to understand why so many are tempted to add this stunning specimen to the home landscape. However, these popular evergreen shrubs are known for their finicky needs. In fact, in some areas, gardenias require considerable maintenance.

Planting gardenias successfully requires careful research in order to ensure that the plant’s specific needs are met.

Outdoor Gardenia Care

There are several factors to consider before planting gardenias. The selection of an ideal planting site is key. Getting the light right is important, as is the soil. And, of course, there's the weather to think about.

Can you leave gardenia outside in winter?

Gardenias won't be killed by frost, but they are cold-sensitive and may die during severe winters. Growth and flowering will slow if night temperatures start to fall below 60 F (15 C). Most gardenias can withstand temperatures down to 20 F (-7 C), though dwarf varieties tend to be less cold hardy.

If your gardenia is killed by frost, don't give up. It can sometimes grow back from the roots in the spring.

Because of their minimal cold hardiness, gardenias are typically grown outdoors in climates with mild winters, or grown in pots and moved indoors for winter. Fall or spring is the most suitable time for planting outdoors.

Sun

Though it's possible to grow gardenias in full sun, most will perform best in partial shade -- that is, locations which receive early morning sun but are shaded from direct sun during the hottest parts of the day.

Soil

Gardenias prefer moist, but well-drained, rich, acidic soil with plenty of organic matter. Amend your soil with compost and manure and, in the case of alkaline soils, blood meal or acidulating fertilizer.

Watering

Though the shrubs require soil that drains well, consistent moisture throughout the growing season is much needed. This means that routine watering will be an essential aspect of their continued care, specifically during prolonged periods of drought and/or extreme heat. The use of mulch may be especially helpful to better maintain consistent moisture levels within beds.

Fertilizer

Seasonal application of a slow-release fertilizer will help to promote new growth and increase bloom. A fertilizer that is specifically formulated for acid-loving plants, such as those used with azaleas or camellias, is generally the best option. Be careful not to over-fertilize gardenia plants. Too much fertilizer can lead to salt accumulation, which can damage the shrub.

The ideal time to begin feeding gardenia bushes is in the spring, just after all chances of frost have passed. After flowering, the frequency of feeding should be reduced, and then cease as fall approaches. Do not fertilize gardenias in the fall, because it can stimulate growth. This tender, new growth will quickly die when exposed to cold winter temperatures.

Pruning

Many growers may find it necessary to prune gardenia plants in order to maintain their desired size and shape. This is best done in late spring or early summer, after the plants have stopped blooming. At this time, dead or damaged branches may be removed from the plant, as well as any faded flowers.

Problems

Though gardenias are considered to be resistant to deer and other browsing animals, they may encounter issues with insects. Common pests that feed on gardenias include whiteflies, aphids, mealybugs, and spider mites. Fortunately, most infestations are fairly easy to treat. Common gardenia diseases include chlorosis, powdery mildew, mold, and root rot.

Symptoms affecting the plant’s waxy foliage, such as wilted or yellow leaves, are often the first signs that the plants may be stressed.

Indoor Gardenia Care

The gardenia plant can also be successfully grown in containers and treated like houseplants indoors. However, when growing a gardenia bush indoors, you must keep in mind that it requires bright light and high humidity.

The dry, short days of winter will likely be the most troublesome. The ideal temperature for gardenias is between 70 and 75 F (21-24 C) during the day and 60 to 62 (15-17 C) at night. Keep your plant away from doors and drafty areas to protect it from cold air. Moving it to a southern-facing sunny window and/or supplementing with grow lights are good ways to get as much direct sunlight as possible during winter.

High humidity is essential to indoor gardenia care. Dry air will quickly cause the flowers to begin dropping from the plant. There are several ways to increase humidity in the home, including the use of a humidifier or grouping plants together on trays of wet pebbles. Misting the gardenia plant is not recommended, as this may cause problems with fungal leaf spots.

The soil, which should be loose and organic, should be kept moist, but take care not to overwater. Monitor the soil frequently for moisture and water thoroughly as the top inch (2.5 cm) of soil dries.

Taking care of gardenia plants requires a lot of work, as they are quite finicky when their growing requirements are not met. This includes fertilizing gardenias, which provides them with necessary nutrients for healthy growth and vigorous blooming. With the help of a good fertilizer, gardenias can be spectacular.

Taking Care of Gardenia & Growing Gardenia Plants

Gardenias require bright, indirect light. They also need moist, well-drained, acidic soil for optimal growth. Gardenias also thrive in humid conditions, so when growing gardenia plants, use pebble trays or humidifiers to add moisture to the air. Gardenias prefer warmer days and cooler nights as well.

Fertilizing Gardenias

An important part of taking care of gardenia plants is to give them fertilizer. Gardenias should be fertilized in spring and summer. Fertilizing gardenias in fall or during winter dormancy should be avoided. In order to prevent over fertilization from occurring, you should apply fertilizer about once a month. 

Mix fertilizer directly into the soil or add to water and apply to the soil. Using less than the recommended amount will also help minimize the likelihood of burning plants by over fertilizing. 

Whether using powder, pellet, or liquid fertilizer, gardenias require a type specifically designed for acid-loving plants. Those with additional iron or copper, which enhances leaf and flower development on growing gardenia plants, are good choices as well.

Homemade Gardenia Fertilizer

As an alternative to using pricey commercial type fertilizer, gardenias benefit from homemade fertilizer as well. These are just as effective. In addition to amending the soil with compost or aged manure, these acid-loving plants will appreciate coffee grounds, tea bags, wood ashes, or Epsom salts mixed into the soil as well. 

Since they are rich in nitrogen, magnesium, and potassium, coffee grounds are oftentimes a more favorable homemade gardenia fertilizer. Coffee grounds are also very acidic in nature. 

Of course, watering the soil around plants with a white vinegar and water solution (1 tablespoon of white vinegar to 1 gallon of water) can also increase soil acidity.

While their fragrant, creamy white flowers, tucked amid glossy evergreen foliage make gardenia plants (Gardenia augusta syn. G. jasminoides) a popular addition in or around the home, these stunning beauties are not the easiest plants to grow. Often gardeners have issues with gardenia buds falling off the plant or when gardenia buds won't bloom. Let's look at some of the issues that can cause this.

Dropping of Buds on Gardenia Bushes

A commonly seen problem is gardenia buds falling off plants. This can be caused by a variety of things. Probably the most common reason for gardenia buds falling off plants is a change in location. Gardenias do not like to be disturbed. They are extremely sensitive to being moved or even touched. Try to keep gardenia flower plants in one location, moving as little as possible. Dropping of buds on gardenia bushes can also be due to improper watering. Gardenias like to be kept moist. If they are allowed to dry out too much, they will respond by dropping their buds. Insufficient watering, as well as overly dry air, causes the buds to rot. Keep the soil evenly moist and increase humidity levels.

Gardenia Buds Won't Bloom

Even under the best of circumstances, problems with gardenia flower buds happen. For instance, one common problem is when gardenia buds won't bloom. Not enough humidity is oftentimes the reason for this, therefore, you should increase the humidity levels in the home using a humidifier or placing a tray of pebbles with water beneath the pot. Seasonal changes can also inhibit blooms, as gardenia flowers come in and out of bloom with the seasons.

Prevent Gardenia Buds Falling Off Plant

Proper care of gardenia flowers will help prevent gardenia buds from falling off. Sometimes when gardenia buds won't bloom or fall off, it is due to improper care. Gardenia flowers require lots of light, however, you should avoid direct sunlight. These plants also prefer to be kept moist, not wet, but do require slightly drier conditions during non-flowering intervals. Use peat-based potting soil, if possible. While gardenia flower plants will tolerate a range of temperatures, they prefer cool nights, between 60 and 65 degrees F. (16-18 C.), and warmer days, about ten degrees higher. Gardenia flowers thrive in humid conditions, therefore, the use of humidifiers or pebble trays is important, especially during winter. Gardenias benefit from a monthly dose of fertilizer and, although not a requirement, gardenias can be pruned for shape after flowering has ceased.

Other Problems with Gardenias

In addition to non-blooming buds and the dropping of buds on gardenia bushes, other problems may be seen, such as the yellowing or dropping of leaves. Exposure to extreme temperatures, especially cold, can lead to all of these problems. Make sure that gardenia plants are kept away from drafts. Improper watering due to overwatering can cause problems as well. Check to see if the plant is too wet. Also, use distilled water whenever possible, as gardenias are sensitive to large amounts of lime found in regular tap water. Leaf or bud drop is common when gardenia plants are too dry, either from lack of moisture in the soil or air. Once again, increasing humidity levels can help. Poor light conditions are another possible reason. Keep gardenias in well-lit areas. Growing gardenia flowers doesn't have to be a chore. Provide the best optimal care and these magnificent plants will reward you with beautiful, fragrant blooms.

Though gardenia plants are very beautiful, they are notoriously tricky to take care of. Growing gardenias is hard enough, so it's no wonder that many gardeners shudder at the thought of transplanting gardenia plants.

Care of a Gardenia Bush Prior to Transplanting

Proper care of a gardenia bush prior to transplanting is crucial to the success of transplanting. Make sure that your gardenia is in the best shape possible, free of fungus and pests. If your gardenia is ailing from any problems, do not attempt to transplant it until you have addressed its current issues.

Best Time for Transplanting Gardenia Bushes

The best time to transplant gardenia plants is in the fall, after the plant has finished blooming. Gardenia plants transplant best when the weather is cool and the plant is slowing down. About a week before transplanting gardenia bushes, prune the branches back by one-quarter or one-third. This will reduce the overall size of the growing gardenias and allow them to focus more on their root system.

Best Location for Gardenias

Gardenia plants need rich soil with light shade. They also need soils that have a pH balance between 5.0 and 6.0. Choose a location that has organic, rich soil or amend the soil prior to transplanting gardenia bushes.

Transplanting Gardenia

Once you are ready to transplant your gardenia, prepare the hole where the gardenia will be moved. The less time growing gardenias spend out of the soil, the better the chances that they will survive. When digging up your gardenia plants, dig as big a rootball as possible around the plant. The more soil and roots around the gardenia that go with the gardenia to the new location, the better chance your plant has to survive. Once you get the gardenia to its new location, backfill to fill any gaps and tamp the rootball down firmly to ensure good contact with the soil around the hole. Water thoroughly, then water every other day for one week following. Transplanting gardenia plants can be easy if it is done carefully.

Gardenia Leaves Turning Yellow: Common Causes & Easy Fixes

If you’re concerned about yellowing leaves on a gardenia, you’ve come to the right place. A staple of the southern landscape, heavily fragrant gardenias remain among the most beloved plants for the ornamental garden. With their prolonged flowering period and attractive evergreen foliage, it’s easy to understand why gardenias are a perennial favorite.

Most gardeners consider gardenias easy to grow, but it’s crucial to monitor beds and borders for potential problems. Yellowing leaves, also known as chlorosis, is quite common in gardenia plants. Determining the exact reason why gardenia leaves are turning yellow requires some careful diagnosis.

Why Are My Gardenia Leaves Turning Yellow?

Yellow gardenia leaves can be caused by a variety of factors. Sudden changes in cultural conditions are usually the culprits. These changes can include fluctuations in temperature, soil moisture levels, and even the availability of nutrients. In gardenia plants, yellowing may also indicate disease or insect pressure.

Common Causes for Yellowing Leaves on a Gardenia

Rapid changes in weather are most often the cause of yellowing leaves. Cooler nighttime temperatures or brief periods of cool weather are likely to trigger minor yellowing.

Over or underwatering can also lead to a change in the appearance of a gardenia’s foliage. Also, check your garden soil for incorrect pH levels or deficiencies in iron and magnesium. These issues can be resolved quickly.

Yellowing gardenia leaves is a common sign of disease. Fungal disease, rot, and other issues that affect the plant may first manifest as a change in appearance. Nuisance insects may also cause gardenia leaves to turn yellow. Aphids, whiteflies, and spider mites are of particular interest, though these seldom cause severe damage to established gardenia plants.

How to Fix a Gardenia With Yellow Leaves

Solving soil issues will remedy most problems with gardenias. These include routine irrigation, using a high-quality fertilizer, and monitoring of pH levels in the soil.

Most successful gardenia growers recommend an inch of water per week. Soil should be kept moist but not soggy, so be sure to use well-draining soil.

Gardenias are happy with 5.0 to 6.5 pH values, so after testing your soil, you may find you need to make amendments. They love acidic soil and may enjoy a bit of coffee now and then.

While several diseases that affect gardenias are only minor, some more severe infections may lead to the loss of plants.

How to Prevent Gardenia Leaves Turning Yellow

The best way to prevent yellowing of gardenia leaves is to establish a consistent care routine. This will help to ensure that their ideal conditions for growth have been met.

Gardenias need soil that drains well, sufficient light, and ample space between each plant for adequate airflow. Using proper irrigation techniques will further help to prevent the occurrence and spread of disease within the garden. Talk to your local extension service agent or garden center expert for recommendations before applying chemicals to your gardenia.

Frequently Asked Questions

Should You Remove Yellow Leaves From a Gardenia?

Most yellow leaves on gardenias will fall from the plant on their own. However, removing affected foliage can help to maintain a more attractive appearance. Yellow leaves that are believed to have been caused by disease should be removed immediately. Infected leaves and other debris should then be removed from the growing space.

What Does an Overwatered Gardenia Look Like?

Gardenias that have been overwatered will often begin to yellow. Should waterlogged conditions persist, growers can expect the leaves to wilt and begin to drop from the plant prematurely. In severe cases this will lead to the development of root rot, various fungal diseases, and the complete demise of plants.

A gardenia flower is truly a beauty to behold and the scent is just as wonderful to experience. Unfortunately for many gardenia bush owners, gardenias are notoriously tricky to coax into bloom, but it can be done. Care and feeding gardenia is key to getting a gardenia bush to bloom.

Care of a Gardenia Bush

In order to get a gardenia to bloom, there are four things to remember about proper gardenia care. These are:

• Humidity
• Sunlight
• Temperature
• Fertilizer

Humidity - Care of a gardenia bush means providing lots of humidity. If your gardenia is in a container, setting the container on a dish filled with pebbles and water will help to increase the surrounding humidity. Whether your gardenia bush is planted in the ground or in a container, daily misting with a spray bottle will increase the humidity around the plant. Sunlight - Taking care of a gardenia bush also involves making sure that the plant gets proper sunlight. An outdoor gardenia should be planted in a sunny location that is shaded somewhat during the hottest part of the day. For indoor gardenia bushes, place the gardenia in a bright light location but not in direct light. Temperature - Gardenias bloom best when the daytime temperatures are warm but not hot and the nighttime temperatures are cool. Ideally, for the day, you want the temperatures to be between 65 and 75 degrees F. (18-24 C.) during the day and between 55 and 60 degrees F. (13-16 C.) at night. For proper gardenia care, make sure that your plant is in an area where the temperatures will match this pattern. Fertilizer - A gardenia bush is a heavy feeder. Proper care and feeding gardenia means that you should be fertilizing your gardenia every two weeks with a regular water soluble fertilizer solution. Once every three to four months, fertilize your gardenia with an acid based fertilizer. Gardenia care can be time consuming, but the gardenia blooms are certainly worth the effort. Taking care of a gardenia properly will reward you with the lovely and heavenly scented flowers that make gardenias so special. Proper care and feeding gardenia bushes is all it takes.

Gardenia bushes are the apple of the eye of more than a few warm-weather gardeners. And with good reason. With rich, dark green leaves and snowy, soft blossoms, the gardenia impresses on its looks alone, but it's not its looks that make the gardenia such a coveted garden addition. Gardenias have won the hearts of their gardeners because of the flower's exquisite scent.

How to Prune a Gardenia

For as beautiful as gardenias are, however, they are a shrub and like many shrubs, gardenias can benefit from being pruned occasionally. While it is not absolutely necessary to the health of the plant that you prune your gardenia shrub, pruning helps to keep your gardenia shrub shapely and the correct size for its location in your garden. 

Because pruning is not essential to the health of your gardenia, it does not have to be done every year. Pruning a gardenia every other year or so will be enough to keep its size manageable. You only need to prune enough to help your gardenia keep its appropriate size and shape. Make sure that you use sharp shears when pruning your gardenia, like the Felco F6 Pruning Shears from Amazon, as this will help to prevent jagged cuts which can lead to disease in your gardenia shrub. 

There are many different theories about what kind of wood on a gardenia should be pruned, but for the most part, experts agree that it is okay to prune both green and brown wood on most varieties of gardenia. Most varieties of gardenia set buds on both the green and brown wood and, therefore, will set blooms regardless of where you prune the bush.

When to Prune a Gardenia

It is best to prune your gardenia shrub right after the blooms have faded in the summer. Gardenias will set their flower buds for the next year in the fall, so pruning in the summer will allow you to cut back some of the older wood without risking cutting away newly set buds. 

Most varieties of gardenia only bloom once a year, though breeders have developed a few varieties that can bloom more than once a year. Before pruning your gardenia, make sure to check that the variety that you own only blooms once or has completed its blooming cycle if it does bloom more than once. 

While it may be difficult for you to think about cutting away a little bit of such a luscious plant, the fact of the matter is that your gardenia will be much less likely to turn into an unruly beast if you give it a regular pruning.
