The Q&A Archives: Digging Dahlia Tubers Early

Question: We are moving and we want to take our family heirloom dahlias with us. What is the absolute earliest that we can dig these dahlias up without damaging them?

Answer: Typically, dahlia tubers are lifted from the ground after the first frost. This allows the maximum time for foliage to supply the tuber with nutrients for the following year. So the longer you wait, the better. However, since they have been in the ground for most of the growing season you should be able to cut back the foliage and dig them now without them losing too much of their strength.
