Q.Squash Plant Blooms Mostly Female Blooms And Very Few Males
I am growing zucchini squash plants in pots in a greenhouse. I did this last year with no problems. I am getting lots of female blossoms but very few males and not at the same time. I am attempting to save pollen. The varieties I am growing are Grey, Cocozelle and Dirani. They get fertilized once a week. What can be done to balance the types of blooms
