Great looking pumpkin vine/only one pumpkin.

Question

My pumpkin vine has beautiful blossoms and leaves but only one, white pumpkin. The blooms are falling off before a pumpkin sets. The plant appears healthy, no apparent infestation or fungus, rich soil among coneflowers, black-eyed susans and morning glories. Ordinarily it gets at least 6 hrs. of sun. We did get several inches of rain a couple weeks ago. Could that be the issue or is there something else I am missing?

Answer 1

There are many reasons for a healthy vine but no pumpkins. This article should help. You may need to try hand pollinating.
