This is what I found when I checked my garden this morning. Two of my cukes just laying on the ground. The first one in this picture has about 1" of the stem sticking up out of the ground. I have never had this happen in all my years of gardening. My first thought was a cutworm. How can I prevent this?
My first thought would be there was a raccoon, woodchuck, squirrel, rabbit, deer, person, dog, cat, or other largish critter tromping through the garden and broke them off. The cardboard tubes would help with that sort of thing too.
My garden is well fenced and there were no animals in there. If by some very slim chance one had got in there would have been visible tracks and there were none. We live in the middle of the woods and it's just about as secure as Fort Knox! It's even got electric fence around the bottom, middle and top. My husband said maybe a grasshopper did it. Is that possible?
