This photo is pretty indicative of what I'm seeing. It is by far worst on the zuchs, although there is some damage on the yellow squash and cukes. These poor little plants were just getting started. Of four little plants started, one has been mowed down completely, and the other three look like this. The seed leaves have been pretty well chewed, and the first true leaves that were just getting started are completely gone. I don't have a lot of hope they'll recover, so I'll probably be putting in some replacements. Anyway, whaddya think is doing this? I see no critters at all. I've has issues with slugs in the past, but I feel like I have that pretty well under control and haven't seen any slugs there, even after dark when it was rainy and damp. Thoughts?
