Dahlias are a beautiful, bright flower that blooms from mid-summer to late autumn when many other plants are beyond their prime. Late in the spring, the tubers are put in the ground. If you want to grow them as perennials in colder climates, you’ll need to dig up and store the tubers in the fall (or, treat them as annuals).

Dahlia is a genus of tuberous plants of the Asteraceae family, with sunflower, daisy, chrysanthemum, and zinnia as close relatives. They are made up of little tubers that are planted in the spring. Choosing a favorite dahlia is akin to sorting through a package of buttons.

Dahlias have fragile tubers that will not withstand a freeze. Early in the spring, you need to start them undercover, and then transplant them outside once the frosts have passed in late May or June.

Is it true that dahlias return year after year?

The tubers can be dug up in the fall, stored over the winter, and planted again in the spring. Dahlias are not considered biennial flowers. They re-sprout from their underground tubers to blossom each year in their natural warm environment.

In my garden, where should I grow dahlias?

Dahlias perform best when planted in full sun with healthy, well-drained soil. Dahlias for borders can be spaced 15 inches apart from center to center, whereas regular types are usually placed around 18 inches apart. Loosen the soil to 12 inches depth.

Is it necessary to soak dahlia tubers before planting them?

Soak tubers in a bucket of lukewarm water for an hour before planting to properly rehydrate them. Starting your dahlia tubers in pots will stimulate them to develop more quickly, which means they’ll be ready to flower sooner.

Dahlias should be planted how deep?

Dahlia tubers should be planted outdoors in the spring once the frost has passed, 10cm deep in healthy, well-drained soil. They prefer to be in a sunny position with 45cm spacing between them. Dahlias should be dug up and stored in a cool place for the winter in areas where it is extremely cold.

Can you plant dahlias in pots/containers?
