Dahlia Tubers

Dahlia Tubers

Dahlias are one of the highlights of the late summer garden, offering full-on colour and an almost endless variety of shapes and sizes. Grown from tubers (the roots of mature plants), they’re a brilliant way to create vivid, dramatic borders with little effort – and they make fantastic cut flowers, too!

From classic pompons to delicate single blooms and dramatic cactus dahlias, Fothergill’s range of dahlia tubers has something for everyone. Starting your dahlia tubers in pots in early spring helps them establish faster and encourages earlier flowering.

Discover our dahlia tubers below, or browse our full collection of flower bulbs and tubers to plan your next display. You can also explore our dahlia seeds if you want to try your hand at growing your own plants from scratch.

When to Plant Dahlia Tubers

Dahlia tubers are spring-planting flower bulbs, so start them in spring for a spectacular summer display. Plant your dahlia tubers outdoors once the risk of frost has passed, typically from late May through June. If you want a head start, begin them in pots from March onwards. Keep them in a bright, frost-free spot, such as a sunny windowsill or greenhouse, until it's warm enough to move them outside. The earlier you start, the sooner they’ll flower. 

How to Grow Dahlias from Tubers


Choose a sunny, sheltered spot with well-drained soil. Plant each dahlia tuber around 10-15cm (4-6in) deep with the growing point facing up, spacing them about 45cm (18in) apart. Water well after planting and continue to water regularly through dry spells. As shoots appear, generally around 2-4 weeks from planting, pinch out the growing tips to encourage bushier plants. Taller dahlia plants benefit from staking early to support their heavy blooms later in the season.
