Hi, I am a beginner gardener and I have two bell pepper plants and a zucchini plant growing in pots currently. They seem to be growing great so far, just have a couple problems with the leaves. On the bell pepper plant there pretty large holes in a couple of the leaves that I'm guessing is something eating them. Does anyone know what it could be from the picture? I haven't seen any bugs on the plant. For the zucchini plant, some of the leaves have gotten brown drying rings around the edges. I don't know what this is from and was curious if anyone could tell me. I have also just found a ton of gnat-looking bugs covering my zucchini plant and would like to know some home remedies to keep them away? I do not want to use any unnatural pesticides on my plants.
Thanks everyone!
