Planting dahlias is not very difficult. as they are either grown from seed or tubers. Dahlias come in a variety of colors and sizes, and are quite versatile in the garden. Nothing makes your summer garden stand out more than these colorful blooms. Keep reading to learn more about how to plant dahlia flowers.
How to Plant Dahlias
First time dahlia growers often wonder when to plant dahlias. Planting dahlia tubers can be done in the spring.
If you start planting dahlias from seed, you should start them indoors or directly in the garden once the temperatures are warm enough. Dahlias will typically germinate in five to seven days. Once they germinate, you will want to keep an eye on them and make sure that they are watered enough, but don’t soak the soil.
You can also purchase tubers or divide existing dahlia plants and use them for planting dahlia tubers – dig up the root ball of the dahlia and separate the tubers so you can transplant them. Make sure each of the tubers has one eye. Place them about an inch (2.5 cm.) into the soil.
Make sure you are planting dahlias where there is enough sunlight but also some shade. They like five to six hours of sunlight each day, but that’s about it. You should see life from the tuber you planted within a week.
When it comes to fertilizing dahlias, you can use a 5-10-15 or 5-10-10 fertilizer when planting at a rate of about 2 pounds per 100 square feet.
You should plant larger dahlias about 3 feet (91 cm.) apart. Smaller ones require less space and can be planted closer.
Caring for Growing Dahlia Flowers
You will want to keep the area as weed free as possible. Mulch can help with this regard.
Some dahlias will grow quite large. When they reach about a foot (30 cm.) tall, you can tie them up to a stake for support. As they get taller, you can add ties. Further, when the plants are about 15 inches (38 cm.) tall, you will want to start pinching off suckers. If you leave the suckers on the dahlias, it may rob the plant of nutrients and result a weaker plant.
So, as you can see, dahlia planting can be done pretty easily. They are somewhat pest free, and as long as dahlias are cared for adequately, you should have no trouble enjoying their colorful blooms throughout the summer season.
