|The Zucchini plants appear to be very healthy, the flowers are beauriful. The squash will form and when, in most cases, it reaches a length of about three (3) inches, the vegetable will start rotting on the flower end and eventually die. Is this from overwatering or some sort of an infestation or what?
|Overwatering can cause rotting fruit, but the likely cause is incomplete pollination. Female squash blossoms have an immature fruit already forming behind the flower. The fruit will begin to develop and then abort if it's not completely pollinated. Remove the malformed and rotting squash so the plant can put its energy into developing new fruit.
