How to Store Dahlia Tubers – A Beginners Guide

Understanding when and how to store Dahlia tubers can be tricky for those who are new to gardening. Dahlias are incredible summer flowering plants that bring joy to those who grow them. Growing from a tuber (a dry clump formation of roots, rather than a bulb or plug), Dahlias are perfect perennials that flower throughout the whole season.

However, once the summer season is over, there’s a process you should follow to protect the root and ensure that the plant doesn’t rot. If this is your first time storing dahlias, then this handy guide can help you go from A to B without any fuss or confusion.

Step 1 – Lift the Root

Lift your tubers before the first frost of the autumn season to avoid root rot. To lift the root, you need to dig gently around the base. Be careful not to damage any of the root as you dig. Shake off the soil and cut the dahlia stems down and dispose of the leaves.

Step 2 – Rinse & Dry

Rinse gently with water until most of the soil has washed off. Leave in a warm area, with the tuber placed upside down, to dry.

Step 3 – Pot and Cover

Once the tuber has dried, place in a pot and cover with dry compost. Store in a dry, cool area until the weather warms once again and repeat the cycle.

Gardening Tip 💡 : If you know that your dahlias are in a warm, safe spot in your borders and aren’t at risk of rotting throughout the winter, cover the area with a thick layer of mulch for an added padding of insulation.

How to plant Dahlia tubers

  • Plant dahlias on free-draining, lighter soils, where they are more likely to survive the winter.
  • Plant in a sunny or partially shaded location for best growth.
  •  Space about 60cm (2ft) apart and 10-15cm (4-6in) deep.
  •  As dahlias are tender, you’re best starting the tubers into growth in the greenhouse, then plant them in their flowering site after the frosty days are passed.
