Dahlias and Winter - Knowledgebase Question

Question by nicole_silve

Will my dahlias come up again next year, since they are bulbs, or do I have to dig them up and bring them in for the winter (as my mom believes)? If I do have to bring them in, what exactly does that entail?

Your mother is right. Dahlias must be dug each fall in cold weather climates. After frost has nipped the
foliage and stems of your Dahlias, cut the foliage down to
the ground. Then carefully dig the tubers and lay them in the
sun for a few hours to dry. Then shake off excess soil. You
can store them in sawdust, dry sand, peat moss or
vermiculite in a cool (40F - 45F), dark place. In the spring
the tubers can be divided before they are planted. Each
swollen tuber that has a bud forming at the stem end can be
cut away from the others and planted. Cut with a sharp
knife, taking part of the original stem with each division.
