Bonnie Thomas suggests putting dahlia tubers in a warm, moist area for a week to check on health of the sprouting buds. What exactly would constitute a warm, moist area? Warm, damp soil? Warm, damp vermiculite? Thanks for your help... Wendy

In spring you can move the tubers to a dark and warm location.
This should be enough to encourage eyes to develop.
Approx. 15 days before you are going to plant the tubers you can place them in plastic bags and add 1 teaspoon of water retie the bag and continue in the warm location.
