Overwintering Dahlias IN GROUND
Anyone ever try overwintering Dahlias in the ground? I am in Southern WI/Zone 5.
Not this winter but the last, when one of my Dahlias frosted and wilted,the hubby piled leaves on it and never went back to clean the leaf pile up. In the spring when I cleaned the pile up I didnt think much of it but later, the plant came up! I was shocked. Did I just get unbelievably lucky or is there something to doing this (instead of digging them up)?
I actually dug the tubers up this past fall because I was afraid I *just got lucky* but has anyone experimented with doing something like this? I know I have PLENTY of leaves that I could pile on if it could work.
