Dahlia Tubers

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.
