I have quite a lot of pumkins growing on my allotment and all have started to produce female flowers. Over the last couple of weeks these have been swelling and now some are the size of tennis balls. The thing is I haven't had any male flowers open for pollination. How long will a pumpkin continue to grow before it fails due to lack of pollination?
Obviously my pumpkins could be pollinated by pumpkins growing elsewhere but I'd doubt they've been pollinated by my plants!
