The garden where these tomatoes are trying to grow is fully surrounded by a 7' fence which is closed up tight when I am not in it. No deer have been able to get in. The bites are too big to be squirrel or chipmunk. To my knowledge, I do not have small children or trolls sneaking in to nibble my veggies while I'm sleeping.
We did see a skunk (my first up-close one!) on our back deck about a week ago...could he be the culprit?
