I have a zucchini plant that is green and healhy and the vines are thick and sturdy, but for some reason one of the plants will grow fruit 2-3 inches long and then turns yellow and rots. The other side of that same vine will get green zucchini that grows just fine. What is the cause of the rotting yellow fruit, and how do I fix the problem?
