I have an old Dahlia tuber from my Grandmother that I've kept alive for the
past 20 years or so and this year the tuber never shot new growth so about a
month ago I gently dug the tuber up and believe it or not it was firm (no
rot noticed) but cannot see an eye for new sprouts. Someone suggested I dip
the one end of the tuber in rooting powder and rebury it. I still see no
growth. I am in the Chicago area and will be digging up the Dahlias in a few
weeks for Winter storage. Any comments/advice on this tuber would be most
welcome via posting here or email at email@example.com.
Thank you very much in advance for any assistance!
