Quick off subject question: RE: zucchini and yellow summer squash. I am beginning to have cute little squash ONLY they develop a little and wither, or develop a little more 3" and the end begins to rot. Am I watering too much? Not enough heat? Weather has been in the 50's, now is in the 70's. My tomatoes and chiles seem happy enough, but they'd like some more hot sun I know. HELP! Mary-Anne
