Lifting Dahlia Tubers

dahlia neck dusted with Decided to lift all dahlias and put them into store over winter. Recent rains has left soil in ideal condition for lifting - not too wet, yet not too dry.

It is important to use a fork or spade deep enough to reach the bottom of the tubers, if damage it to be avoided. I use a fork.
  • Insert fork to full depth about 25 - 30 cm (10 - 12 inches) away from stems and pull handle backwards with one hand whilst pulling foliage with other hand. Take care not to pull foliage too hard, to avoid tearing.
  • Cut down stems to within 5 cm (2 inches) of tubers, then label.
  • Dust neck of tuber with "Derris" dust. This is where wireworms seem to attack in storage.
  • Invert tuber to drain moisture out of stems.
  • Leave inverted for a few weeks to cure (tubers go soft and rubbery, and are able to withstand more frost).
