Well, that is certainly an illuminating idea!
Yes, I have to admit that autumn olive seems to have some advantage on poor
sites. Untended fields in this area are prone to growing a lot of
broomsedge, which indicates low pH, low N and low P. If autumn
olive were to move in, I don't think anything would stop it till a
forest grew up through it and shaded it out. Which I have no doubt would
happen, given the apparent availability of the N fixed to surrounding
plants. Donna
