I planted my zucchini this year with high hopes of having enough zucchini to make squash pickles this year. The plant itself is hardy and robust with huge green leaves. The problem is that the blossoms are falling off once they've bloomed instead of producing anything. I've never seen anything like it. Has anyone else had this problem? And what do I do about it??? I water almost every day to every other day. I'm afraid I won't have any zucchini this year at all.
