Ok well my pumpkin plants are doing great exept for one thing. The female flowers are not developing to even open they are falling off premature about 2 days before flowering. I havent seen one yet that bloomed. Plently of male flowers but not one female flower. From growing pumpkins a couple years i got down how to pollinate it myself and i never had this problem. I have them sprayed to keep the leaf fungal infections down. I can see whats the problem.The vines are spread all over the yard.
