Q.No Female Zucchini Blossoms
Our zucchini plants are huge and very healthy with many blossoms, but 95%of them are male blossoms with no fruit forming. We live in NH. It’s a very hot summer, but we water every other day. What causes this problem and how do we treat it so plants will produce squash?
