Ok, Sharon here in Upstate SC. I am relatively new to dahlia growing - at least the digging up and storing part. previously they have overwintered in the ground just fine for me.
This year however, I dug up ~ 15 plants as I want to rework the bed, since I now have a tiller.
I let them air dry on a covered porch, then carefully put each type in an open plastic bag with label and took them to the basement.
When I checked on them after a couple of weeks, several had a fuzzy white mold. I moved those to open shelving on my outside porch and sprayed each with a bleach solution. Now even more of those left in the basement have the fuzz.
We are in the start of our rainy season here. It is probably only going to get worse in terms of dampness.
Is all lost? Do I toss them all, or are there desperate measures to be taken?
If they can be treated, I have an unheated room they would probably do better in than my basement. They did however, do just fince there last winter.
