Dahlia Tubers
Dahlias are the showstoppers of the late summer garden, delivering spectacular colour just as many other plants begin to fade. Grown from tubers, which are the fleshy roots of established plants, they're an easy, rewarding way to fill borders with bold displays that last right through to the first frosts. And with blooms this beautiful, they're practically made for cutting!
When you buy dahlia tubers from us, you'll receive healthy, garden-ready stock selected for both colour and performance. The tubers need to be planted around 10–15cm deep. How deep to plant dahlia tubers matters more than you'd think, protecting them from cold snaps while encouraging strong growth. Knowing when to plant dahlia tubers is equally important; wait until after the last frost, typically late April to May in the UK.
After the season, you can store your dahlia tubers over winter and try dividing dahlia tubers in spring to multiply your stock for free.
Plant your spring planting bulbs and tubers this season and enjoy a vibrant, long-lasting show that brings beauty and joy to your garden year after year.

Dahlia tubers are the most reliable way to fill your garden with colour. Buy dahlia tubers from us, and you'll receive healthy, established roots ready to get going the moment they're in the ground, delivering stunning flowers from midsummer right through to the first frosts.
Knowing when to plant dahlia tubers is simple; once the threat of frost has passed, typically late April to May is the ideal time. Choose a sunny, well-drained spot and pay attention to how deep to plant dahlia tubers; around 10–15cm gives roots the best start and protects against any late cold snaps.
Once the first frost blackens the foliage, it's time to lift and store. Knowing how to store dahlia tubers correctly is crucial. Dry them off thoroughly, remove any damaged roots, and keep them in a cool, frost-free place in barely damp compost or sand over winter. Come spring, dividing dahlia tubers is straightforward; simply separate the clump so each section has at least one healthy shoot, and you'll multiply your display for free year after year.
