Question About Dahlia Tubers ?
I have a question, I hope I am not in the wrong forum. Last year I had some beautiful dwarf dahlias, bought as small plants in cells. Twenty four of them. I planted them in the garden and in large pots, and about ten survived all snail, slug and earwig attacks and grew big and flowered marvelously. Fall came, and I read about storing the tubers. I cut the plants just before the first frost ( they weren't killed) and let the short stems with tubers in the ground for few days ( I read for liquids to store in the tubers) I did out the tubers ( they were whitish and looking like bunches of small potatoes) and put them in the basement on top of my laundry machine ( not in use) for dirt and everything to dry out. Within a few days this tubers shrank and shrank as if they were made of only water and skin. Within a week they were like raisins, nothing but some wrinkled skin. So I assumed that's not good, and I threw them away.
This year I want to buy some dahlia again ( I received a catalog with amazing flowers, some "dinner plates" and others.
My zone is cold, so I want to store the tubers properly. I can't afford dahlia as annuals, they're too expensive.
What went wrong with my tubers? Were they bad, or I handled them bad? how can I avoid killing tubers again?
