Zucchini- no female flowers
Hello! I had 6 zucchini plants this year, 3 I started from seed and 3 bought as seedlings from a box store, and in total, my 6 plants produced about 2 female flowers (which I tried, unsuccessfully to pollinate by hand from the available male flowers). I've been growing zucchini successfully now for the past 15 years and have never had this problem before (although I am at a new location before and this is my first garden in my new boxes). Does anyone know what can cause this to happen?
