We have a small organic community garden plot in
Berkeley, California. Lately we have been experiencing ever-increasing numbers
of aphids which are doing considerable damage to our winter greens. We've tried
spraying them off with a high-pressure nozzle, hand-picking them, and just
recently, applying a mild soap solution. Can anyone recommend any other
successful strategies for dealing with these critters, or ways of maintaining
our plot that will make it less desirable for them to inhabit?
