Hi everyone! A friend of mine is growing the plants listed below on about 2.5 acres and he wants help making the trees more productive and more pest resistant. I suggested doing some support plants around, but I'm not sure what kinds of things would grow well. He's 74 years old and it'll have to be stuff that would be easy to maintain, minimize weevils and other parasitic insects and be safe for the grandkids runnin around. Thanks in advance!
