Planting dahlia tubers is easy once you know how. Learn how to plant dahlia tubers, to get your gorgeous dahlias off to a great start.

Planting dahlia tubers the right way will ensure a field or garden full of fabulous dahlia blooms.

It’s very important to plant after the risk of all frost has passed, since dahlias are tender plants, and will not fare well with frost.

A good rule of thumb is to plant your dahlia tubers when the lilacs are blooming.

You can divide tubers in the fall or the spring, whichever is your preference.

Some gardeners start their dahlia tubers early in the spring in pots, to give them a head start on the growing season.

Once the weather has warmed up, and the plants are hardened off, the potted dahlias can be  planted into the garden when the risk of frost has passed.

You can plant dahlia tubers straight into the ground, although it is important that the tubers are planted in an area that has fertile and well drained soil.

There are many different ways to plant dahlia tubers. If planting into the ground you can grow them in rows, or just plant them in a sunny spot in your garden.

Plant in a sunny location in fertile, humus rich soil, which is high in organic matter.

Tubers should be planted at least 4 to 8 inches deep, to help support the heavy dahlia plant as it grows taller.

It’s always a good idea to add compost and bonemeal to the planting hole, as dahlias are heavy feeders.

Space tubers 1.5 to 2.5 feet apart, depending on the size of the dahlia variety. Do not water your dahlias until they are up through the soil and growing well.

If planting dahlias in rows, corralling is a method to hold the dahlias up. You can also stake individual plants within the rows or garden as needed.

Dahlias bloom about two and a half to three months after they are planted. Some of the larger varieties will need a little more time.
