Female Pumpkin Flowers Not Opening
I planted Memorial Day and had females in early July. the first one opened and pollinated and died in a few days, and at the same time, several others died before opening. I looked here and saw that it may be due to high heat. The weather became milder, and plants kept growing wildly, looking very healthy, with males opening daily, and females continuing to die, some very small and some at size when I would expect them to open. It is still happening -- the flowers look very healthy but just do not turn yellow like I expect the day before opening. Can I manually open and pollenate when they are at full size? Is it just too late to get pumpkins?
