I had the same problem. I picked the male flower and poked it in the female flower to pollinate it. It worked I ended up with lovely big pumpkins.

Hi. My pumpkin vine is producing plenty of flowers - but all males! What can I do to encourage some female flowers? It's May, is this the wrong time of year? The vine just popped up out of the compost. Really appreciate any assistance. Thanks for your time.
