Hello. I have started my dahlias inside and now have 50 plants inside my house . . .
All the guides that I read say that dahlias tubers only really get going when soil temperatures reach the mid-60s. Here that's mid June. Do I have to wait that long for transplant my dahlias, or can I do it sooner, especially since the dahlias that I plant in spring keep going right up to the first frost in the fall.
Thank you for the feedback!
