We are going to use movable pvc net fencing to enclose about 1/3-1/2 acre of our yard. I would like to plant a few trees in there. Right now there is NOTHING there now but grass and broadleaf weeds. Oh, and one butterfly bush, which I wonder, should I move it? I'd love to plant hydrangea or snowball bushes (which I would prune up from the bottom so the girls could hide underneath). I don't want to encourage them to fly up to roost in the trees, but they're heavies (buff orps, black australorps, ee's, NH reds and barred rocks), so maybe I won't have to worry about that. But I do plant anything, it'll be small--I'm not spending hundreds of dollars on 8' trees. Any suggestions on how to provide some shade trees/hiding cover for the girls such that they wouldn't be tempted destroy it?
