Hardly ever get to this forum so beg pardon if subject has been published before. I have many year old grafts that were put in ground after Christmas. Deer are snipping off the top buds. I've put cages around them but somehow they still reach them. This week I sprayed a second application of "Liquid Fence" around them. Is there anything short of waiting with a 30/30 to keep the trees safe? Thanks ahead.
