Q.Vegetable garden pests
I have a potted garden. In it are cherry tomatoes, peas, 2 zucchini plants, a yellow squash plant, and a spaghetti squash pant, as well as some radishes. My tomato plant was sick first. Its leaves were stuck together with this white sticky stuff. Inside it were teeny tiny yellowish green bugs. I cut them off and killed them. My squash plants are starting to get holes in them. Some leaves are turning brown and curling. Some leaves are puckering. At the base of a zucchini plant is a yellow discoloration. Some leaves are drooping. My peas were doing great, then all of a sudden went limp and fell over but there still green. What is making my plants sick? How do I get rid of it? All of my plants are relatively healthy looking, so I think I caught this early.
