I have been having the same problem...glad it isnt just me LOL!

I've had a problem occasionally where the female flowers drop off before they grow large enough to open. It usually happens with the first few, then either when the weather suddenly turns really hot and the plants are water-stressed. Check the growing ends and see if you have female flowers coming on very tiny and follow them. If they are dropping off, check if you plants are getting water stress. Have you grown squas successfully there before?

One year I got my plants in late and didn't get any squash set until September...that was winter squash that didn't get ripe!

Hi! Yes, We have successfully had TONS of squash here previously. We had a VERY wet month in late May to Early June (12" rain) and not quite hot days, then it turned just hotter than hammered hades. I have upped the water a bit and it seems to be helping the plants, and am keeping an eye out for girly flowers. I guess some days we are the dog, some the bone. My tomatoes are doing awesome though, and considering, I have had some nice Japanese eggplant. Green Beans are a bit slow, but picking up. Ah well, there's always next year! Thanks for your comments, and I will keep updating on any progress. Happy Gardening!
