I had what I thought was a marvelous idea. In the spring I tilled and planted wild flowers, Sudan grass and alfalfa under and around my 65+- fruit tree orchard. Apples, Cherries, Peaches, Nectarines, Plums, Pears etc. It all grew thru the summer and near mid August I had grasses and flowers a yard high throughout the orchard. And then low and behold, I had massive ant armies in the trees, by the tens of thousands, as well as innumerable insects climbing up the grasses and flowers into the trees. I had to mow it all back.
