I recently planted a garden in my yard for the first time, and something is happening to my black beauty eggplant and a my tomato plants which are a few different varieties. There a green peppers and cucumbers growing also, which seem to be unaffected. I think something is eating the leaves, but all i have are stems left for 3 of my eggplants, and many leaves are gone from the tomato plants. Any advice? I live in NJ.
