Re: [nafex] Care of D. kaki seedlings

Jerry,

You are correct in that I did not mulch above the soil surface, or only to
an 1" or so depth. It sounds like heaping it up will help. I was mostly
trying to point out that in my experience, many species will survive in
pots above ground with minimal care (serviceberry, elderberry, apple, plum,
etc.) but paw paw and persimmon will not in my climate, and it sounds like
not in yours either!
