Early season i had to hand pollinate early in the morning (they close up again by early afternoon) to get them going. And you gotta be diligent cause i find the female flowers tend to only open for a day or two. Is yours at least producing female flowers with a baby squash at the base of the flower?...

I got 3 small ones last season. From 3 plants, it was a hot windy dry summer, everything got cooked.
