When do female squash flowers open?
I am considering hand pollination for the first time this year, because I am losing a lot of fruit due to under-pollination by natural pollinators, a first for me. I'm going to have to plant a more pollinator friendly garden next year. Meanwhile for this year, I've been going out at midday on the weekends, early in the mornings, late in the evening, and I've yet to see the female flowers open on any of my breeds of summer squash. This year I'm growing tromboncino, crookneck, and grey zucchini, and I haven't seen the female flower open on any of them. Males I've seen open, but not females. I do have female flowers, I just haven't seen them opened up. So when do these elusive ladies open?
