Bell Pepper Info And Planting – How To Start Growing Peppers

There may be no more visibly diverse vegetable to be found in the garden than the bell pepper. This warm-season vegetable in the Nightshade family (as are tomatoes and eggplant) is prized for it’s snappy texture, sweet flavor and variety of vibrant colors in greens, purples, reds, yellows and oranges. Native to Central and northern South America, bell peppers have become a staple in home gardens and kitchens worldwide. Eat them raw, stuffed, sautéed, grilled or roasted not just for the flavor and texture but for their plentiful nutrition, especially vitamin C.

Growing bell peppers is simple given the right conditions. These plants thrive in full sun, warm temperatures and well-drained, nutrient-rich soil, ideally with consistent moisture throughout the growing season. Given their origin, they are sensitive to cold, they are typically grown as annuals in most regions, performing best when daytime temperatures stay above about 70–75°F (21–24°C).

Bell peppers can be grown in USDA Zones 3–10 (or higher with protection), though they favor longer, warmer growing seasons. If you are starting a vegetable garden or even want to have a few pots of peppers on your patio, read on to learn how to care for your crop for a bumper harvest.

Quick Bell Pepper Facts

What is a Bell Pepper?

Botanically a fruit, bell peppers are a type of sweet pepper distinguished by their blocky, cow bell shape. Unlike peppers that are in the hot pepper category, bell peppers contain no capsaicin, the compound that creates a spicy or burning sensation in one’s mouth, thereby allowing their sweetness to come through.

Types of Bell Peppers

Bell peppers can by categorized mainly by color and size.

Color

Green peppers are the least ripe and have a less sweet taste than bell peppers of other colors. These are the ones you see most frequently at the market, which speaks to their culinary use.

Left to mature on the vine, green peppers will turn from green to yellow to orange. These have a slightly sweeter flavor than green. Some varieties such as the yellow Golden Giant II and the orange Orange Bell are bred specifically to become these colors.

Red peppers are the fully ripe version of the green pepper. These are the sweetest and most nutrient dense with loads of vitamins A and C. Some popular garden varieties include Candy Apple and Great Stuff.

Bell peppers also come in purple, chocolate and even white colors. Purple Beauty are purple in color from their beginning but do turn red at full maturity. Chocolate Beauty ripens to a brownish maroon And while rare, white pepper varieties such as White Cloud do exist, although they do eventually ripen to a reddish orange.

Size

The standard size of bell peppers most commonly seen stacked by color in your local market are about 3-4.5 in. (7.6-11.4 cm) long and in diameter and weigh about 4-6 oz (120-175 g).

Mini bell peppers are about 2–4 inches (5–10 cm) long and roughly 1–2 inches (2.5–5 cm) wide. They have a more elongated and slightly tapered shape and a noticeably sweeter taste. These mini peppers are often eaten raw, making them popular for lunchboxes, salads and quick snacks.

Planting Bell Peppers

Growing bell peppers is straightforward when you give them what they love: warmth, sunshine and consistently moist, well-drained soil. Planting a crop of bell peppers starts long before putting the plant in the ground or your patio container. Because it is a warm-weather crop, you’ll begin your pepper growing journey by start seeds indoors, then transplanting sturdy seedlings after your last frost. Or skip the seed-starting entirely and purchase baby pepper plants where you purchase your plants locally. With a little patience and heat, they’ll reward you with a steady harvest of crisp and delicious fruit.

When to Plant Bell Peppers

When to plant bell peppers depends on whether you plan to start your bell pepper seeds indoors or plant baby plants from a plant swap or garden store.

Starting seeds indoors gives bell pepper plants the long and warm head start they need for a productive season. You will sow seeds indoors about 8–10 weeks before your last expected frost date. Your seedlings are ready to go into the garden once they have grown several sets of leaves and reach about 4-6 in. tall (10-15 cm). Be sure the nighttime temperatures are consistently 55F (13C) and all danger of frost has passed, and gradually acclimate your seedlings to outdoor light and temperature conditions over the course of a few days.

If purchasing baby plants, you’ll stick to the same guidelines regarding temperature as you would had you grown them from seed. These purchased plants have gotten their start in a warm and cozy greenhouse and may not be completely acclimated to the outdoor conditions.

Best Soil for Bell Peppers

Bell peppers grow best in loose, well-drained soil that has lots of organic matter. This is the best soil for supporting both strong root development and consistent moisture levels. A fertile loamy soil that is amended with compost or aged manure is ideal, as it provides the nutrients peppers need without becoming waterlogged.

Aim for a slightly acidic to neutral pH of 6.0–6.8. Avoid heavy clay soils unless you can improve them with organic material to help with drainage and aeration. Consistent soil quality goes a long way toward producing healthy plants.

Light Requirements

Bell peppers will thrive when given at least 6–8 hours of direct sunlight per day. If possible, more than 8 hours of light is ideal for the best growth and fruit production. Strong light such as from a southerly exposure encourages sturdy plants, lots of flowers, and the development of thick-walled, flavorful peppers.

How to Plant Bell Peppers Step by Step

Growing bell peppers successfully comes down to timing, warmth and consistency. Here’s a straightforward path from seed to harvest:

• 1. Start seeds indoors. Sow seeds 8–10 weeks before your last expected frost, planting them about ¼ inch (0.6 cm) deep in a sterile seed-starting mix. Keep soil temperatures warm at around 75–85°F (24–29°C). A heat mat can greatly speed up and improve the uniformity of germination, which typically takes 7-14 days. Maintain even moisture and provide bright light immediately after germination.
• 2. Provide strong early growth. Once seedlings emerge, place them under grow lights for 12–16 hours daily or in a very sunny window. Keep lights close to prevent legginess. Once the first true leaves appear, begin a light feeding with a balanced fertilizer.
• 3. Thinning. If you sowed seeds in bunches in a single pot or tray cell, thinning ensures each plant has enough space and resources to thrive. Once seedlings develop a couple of true leaves, snip the weaker ones at the soil line, leaving the strongest plant to grow on.
• 4. Pot up if needed. If roots outgrow their containers before transplant time, move seedlings into larger pots to prevent stress and encourage continued growth.
• 5. Harden off seedlings. About 7–10 days before planting outdoors, gradually expose plants to outdoor conditions—starting in shade and working up to full sun and wind. This helps prevent sunburn and acclimates them to fluctuations in temperatures.
• 6. Transplant after frost. Wait until all danger of frost has passed and nighttime temperatures stay above 55°F (13°C). Plant in full sun, spacing plants 18–24 inches (45–60 cm) apart in fertile and well-draining soil.
• 7. Encourage strong growth. Water thoroughly after transplanting and keep soil consistently moist. Adding mulch helps regulate temperature and moisture.

Bell Pepper Care

A pepper crop awaits at the end of a long stretch of warm days. Here’s what to do to ensure that pepper crop is perfect.

Watering

Bell peppers need consistent moisture to avoid stress and resulting issues such as blossom end rot. Try to provide about 1–2 inches (2.5–5 cm) of water per week, adjusting for rainfall and heat. Water your peppers at the base of the plant rather than overhead to keep foliage dry and reduce disease risk. Provide water so soaks deeply into the soil. Avoid letting the soil completely dry out between waterings.

Fertilizing

Bell peppers benefit from steady, balanced nutrition. Knowing when to fertilize peppers is key. Prior to planting peppers in the garden, mix in compost or a balanced fertilizer into the soil. Once flowering begins, switch to a fertilizer slightly lower in nitrogen and higher in phosphorus and potassium to support fruit development. Feed every 2–3 weeks, but avoid over-fertilizing, which can lead to lush foliage with fewer fruits.

Mulching

Apply a 2–3 inch (5–7.5 cm) layer of organic mulch such as straw or shredded leaves around plants after the soil becomes warm. Mulch helps retain soil moisture, regulate temperature and keep down weeds. It also prevents soil from splashing onto leaves, reducing the chance of the plants picking up soil-borne diseases.

Pruning

Bell peppers need minimal pruning. There are two times you can prune bell peppers. Pruning early in its growth by removing some branches can improve airflow and plant structure. Look to remove any leaves touching the soil and consider pinching early flowers to encourage stronger root and leaf development before the plant produces fruit. Removing a few inner smaller branches later as the fruits are developing can help sunlight reach developing peppers and reduce disease pressure.

Staking

Staking pepper plants may or may not be necessary, but it’s a good idea. A plant with strong branches can be quite sturdy, but sometimes the plants can become top-heavy as fruits develop. Use stakes, cages, or small supports to keep plants upright and prevent stems from breaking. It’s a good idea to install these supports at planting time—even though you may not need them—to avoid damaging roots later on. Loosely tie stems to these supports as the plants grow to keep them stable throughout the growing season. I’ve had success using square tomato cages such as the FlexGrow 11.5” cage available from Vego Garden.

Hand Pollination

Pepper plants produce self-pollinating flowers, meaning each flower contains both male and female parts. Peppers rely on some movement within each flower to move the pollen from the anther to the stigma in order to produce fruit. Most often this movement is created by bees, other pollinators and even wind.

During times of stress, such as very hot weather or low wind while pepper flowers are blooming, these pepper plants may need a little help in making that pollen transfer. You have two options. One is to take a few moments to move your hands across the pepper plant to gently shake the pollen, filling in for a gust of wind. Or, you can fill in for a pollinator and attempt hand pollination. Using a small artist’s paintbrush, you can transfer pollen from the flower’s anther to the ovary, jump-starting fertilization.

Protecting from Animals

Like many plants in your garden, bell pepper plants are a potential food source for hungry deer, rabbits and ground hogs. It’s easy to protect your pepper plants from these animals with a few tools. Row covers can protect smaller just-planted peppers. Deterrent sprays such as Bonide’s Repels-All Animal Repellent Spray found at Ace Hardware are also an affordable option. Fencing the entire garden, while more expensive, is also an option to protect all of your crops from the damage these animals can cause.

Harvesting Bell Peppers

It’s easy to determine when your peppers are ready to harvest. Begin to pick the peppers once they are 3 to 4 inches (7.6 to 10 cm.) long and the fruit is firm and green. If they feel somewhat thin, the peppers aren’t ripe. If they feel soggy, it means they’ve been left on the plant too long. After you harvest the first crop of peppers, feel free to fertilize the plants to give them the energy they need to form another crop.

Remember that a green bell pepper will continue to thicken its walls and become sweeter if allowed to remain on the plant. Depending on the variety, it will change color from green to yellow, orange, to red.

When harvesting, take care not to rip it from the branch, as this may cause the branch to break. Use hand pruners or a sharp knife for best removal. I quite like using the Harvest Company’s 6-in. Straight Blade Stainless Stell Bypass Hand Pruner available at Lowe’s for all my vegetable harvesting tasks.

Storing Bell Peppers

Once harvested, store your bell peppers in the refrigerator. They’ll keep well for about 10 days before they show signs of shriveling skin. If you can’t use them within that timeframe, you can wash them then cut into pieces and placed in the freezer.

Propagating Bell Peppers

Peppers can be propagated from seeds as described above, taking care to start seeds indoors and gradually moving them outdoors once temperatures are consistently above 55F (13C) and all danger of frost has passed.

Bell peppers can also be propagated from cuttings. This procedure will create an exact clone of your plant. You’ll select a 3 to 5 in. (7.5 to 12.5 cm.) length of stem from a healthy and well-growing plant. Choose a stem with several small branches coming off it, and using a sharp knife make a 45-degree angle cut directly beneath one of the small nodes where the leaves emerge. You’ll use rooting hormone and a light growing media to encourage new roots to form. Keeping this growing medium consistently moist, you’ll eventually have small roots emerging in about two weeks. From there you’ll transplant this young plant into a larger pot and voila, another pepper plant!

Saving Seeds

Have a pepper plant that produced some amazingly taste fruit? Not sure if you saved the seed packet or tag and will be able to grow the same variety next year? If it’s a variety that is open-pollinated rather than a hybrid, there’s a good chance you can save the seeds and grow them next year.

Choose a healthy pepper that is so ripe it’s starting to wrinkle, one that has been left on the plant for a while. Cut it open and remove the seeds. Spread the seeds out in a single layer and let them dry in a cool, shaded area until they become hard and brittle. Once completely dry, store them in a sealed container in a cool, dark place. For best results, save seeds from open-pollinated plants rather than hybrids, as these will grow true to the parent plant.

Protecting Bell Peppers from Cold Weather

Bell peppers are a warm-season crop and will be one of the first plants to succumb to cooler weather. Even before a frost, prolonged exposure to temperatures in the 40s°F (4–9°C) can cause leaves to drop, poor fruit development, and pitting on pepper skin.

If your pepper plants still have fruits that are ripening yet the weather calls for temperatures in the 40s°F (4–9°C), cover plants with row covers, frost cloth or even lightweight sheets in the evening to trap heat and protect tender leaves. Remove covers during the day if temperatures rise to prevent overheating.

Bell Pepper Problems

There are a number of pest, disease and nutrition issues that can affect your bell pepper plants. Being aware of what those pepper plant problems are goes a long way in knowing how to remedy the issue.

Pests

• Aphids: Small, soft-bodied insects that cluster on new growth and undersides of leaves, causing curling and sticky residue.
• Spider mites: Tiny pests that create fine webbing and cause speckled, yellowing leaves, especially in hot and dry conditions.
• Pepper maggots: My personal nemesis, these are larvae that tunnel inside fruits, causing soft spots and internal decay.
• Cutworms: Soil-dwelling caterpillars that chew through young stems at the base, often toppling seedlings overnight.
• Hornworms: Large green caterpillars that rapidly defoliate plants and may chew on developing fruit.

Diseases

• Blossom end rot: A dark, sunken spot on the bottom of fruits caused by calcium imbalance, often linked to inconsistent watering.
• Bacterial leaf spot: Small, water-soaked spots on leaves and fruit that turn brown and can lead to leaf drop.
• Powdery mildew: White, powdery coating on leaves that reduces plant vigor, common in humid conditions with poor airflow.
• Phytophthora blight: A soil-borne disease that causes sudden wilting, stem rot and plant collapse in wet conditions.
• Anthracnose: Sunken, dark lesions on ripening fruit often with concentric rings.

Nutrient Issues

• Nitrogen deficiency: Pale green or yellowing older leaves and stunted growth.
• Calcium deficiency: Leads to blossom end rot and poor fruit quality.
• Magnesium deficiency: Yellowing between leaf veins, typically on older leaves.
• Excess nitrogen: Lush leafy growth with few flowers or fruits.

Many of the above issues can be avoided with using good cultural practices, such as planting in the appropriate soil, maintaining consistent watering, proper nutrition and spacing, removing damaged and discolored leaves, mulching, hand-removing pests and using organic pest controls when a problem occurs.

Growing in Containers

Growing peppers in containers is an excellent option for gardeners with limited space, and in many cases, plants can perform just as well as those grown in the ground. The key factors are sunlight and water: peppers need at least 6 hours (ideally more ) of direct sun daily (more is better) and consistent watering, since container plants rely entirely on you for moisture. Place pots somewhere convenient so you can water frequently—often once a day, and even twice daily during hot weather. The best thing about planting in containers is that you can move them around to catch the best sun exposure.

Use a rich, well-draining potting mix rather than garden soil, which can compact and restrict root growth in containers. Choose a container large enough to support root development and ensure it has drainage holes. Feeding is also important, as nutrients leach out of containers more quickly; applying compost tea or a slow-release fertilizer monthly helps maintain steady growth. Grown in container, you can extend your growing season by moving them to protect them from cold or wind.

Is your patio already chockablock with containers? Grow your pepper plants in a hanging container upside down! Yes, it is indeed possible, and with the plant lifted off the ground, those rascally rabbits and groundhogs are no longer an issue.

Growing Bell Peppers Indoors

Growing bell peppers indoors allows you to extend the season and even grow year-round by recreating the warm, sunny conditions they naturally prefer. Choose a container with good drainage and use a light, well-draining potting mix. Either start seeds separately as described above, or sow them in the final container. Keep the soil consistently moist until germination, which may take 14–28 days. Bright light is essential in this process, so place plants in a south- or west-facing window or use supplemental grow lights to provide adequate intensity and duration. The Feit Electric 24-in. 19-Watt White LED Linkable Plant Grow Light Fixture available at Home Depot provides full spectrum light and is expandable if your indoor gardening space expands.

Temperature and consistency are key to indoor pepper growing success. Maintain indoor daytime temperatures around 80°F (27°C) and slightly cooler nights. Keep the plants away from drafty windows and frequently opening doors to the outside to prevent temperature fluctuations. Water when the top of the soil feels dry, and feed regularly with a balanced fertilizer to support growth and fruiting. While indoor-grown peppers may be smaller than outdoor ones, they can still produce flavorful fruit with the right care and attention.

It is also possible to overwinter your bell pepper plants by bringing them inside for the winter. Given the right conditions as described above, you’ll have a full-sized pepper plant in spring that will start producing fruit that much fast.

Companion Planting

Plant bell pepper plants with other plants that aid in their growth can help in growing healthy, productive bell peppers. Companion planting means pairing one crop with other plants that deter pests, improve soil conditions, or maximize space. Many herbs make excellent companions—basil helps repel insects like thrips and flies, while parsley attracts beneficial insects that prey on pests. Other herbs such as oregano, rosemary, and dill can also support overall plant health and garden biodiversity.

Vegetables and flowers can be just as beneficial. Crops like lettuce, spinach and chard act as living mulch, helping retain soil moisture and suppress weeds, while beans and peas add nitrogen to the soil, supporting pepper growth. Root crops like carrots and beets help loosen soil and improve root development. However, avoid planting peppers near brassicas or fennel, which can inhibit growth and compete for resources.
