When I bought my house last summer I put in two ash trees. I added two more this spring. The yard was devoid of shade--a precious commodity in a town like Tucson. Since my trees have been attacked by mule deer, who seem to like tender young tree leaves. They damned near killed one of my trees. So far, all trees remain alive. I put out some deer repellent yesterday. I have o idea if it'll work. I'm not really allowed a fence under current HOA rules for our community.
It's amazing when you take up some form of gardening, how defensive you get. I wasn't particularly interested in mule deer until they started attacking my trees. Now I am obsessed with them. I now understand the hatred of the gopher in Caddyshack. I would suddenly be the juror who would acquit the gardener who set of a case of dynamite and blew up the neighborhood to get some rabbit. yes, it changes your outlook considerably. The war goes on.
