I have a shade garden in a back yard.shaded by a dying box elder tree the neighbors are going to cut down. because of the danger it poses and because its dying. my question is is there a devise you can get that shades things for you if there are no large trees to shade your property. I was thinking of growing lab reared lady slippers in the full shade under it by the house but am holding off until i know if such a thing exists. why spend that kind of money if they die from the hot sun.
