I am new to GA gardening, however, I have been a gardener for a long time. Something is eating the WHOLE leaf and many of them from my grape vines, bush beans--and leaving the beans alone, carrots and some sunflowers. What could this be? We have a four foot chain link fence surrounding the garden and poles with string stretched to keep the deer out. My herbs, flowers and beets at this point are untouched. What would this be? "They" are eating up to about two feet. ?????????
