When to cut off the stalks and leaves of a potted EE.
I have 5 very large EE's potted on my deck. I've been told to cut the plant to soil level, get them out of the pots, and store the bulbs in peat moss, in a bin in my cool basement. This is what I do with my dahlias every year. My question is when do I do this? Should I wait until the frost burns the leaves? Or can I just do it now...?
