Hi! Zucchini flower question...my zucchini plants had 1-2 weeks of male flowers about 1-2 weeks ago. And since then there have been no flowers at all. I know the males arrive first, and the females start. I know the males need to pollinate the females and I know you need bees for that. (Last year I had lotsa flowers and not enough bees so not alot of fruit). I can see a couple tiny fruits attached to flower buds, but the flowers have not opened, they are small and tightly closed. This is my second year attempting these zucchini, needless to say I don't really know what I am doing...Any suggestions would be appreciated. Thanks
