The Q&A Archives: pumpkin has lots of flowers but no pumpkins

Question: same as title

Answer: Pumpkins will start out by producing male flowers, then soon will also produce female flowers. (Female flowers have a bulge at the base.) It may be that your vine is still producing only male flowers. If there are female flowers as well, then there is a pollination problem. Using floating row covers will exclude the pollenating insects, or chemical use or rain can interfere for example, or a lack of pollinating insects in general can cause this. You can move the pollen by hand using a soft bristled brush, dab from male to female flowers. Good luck with your pumpkin crop!
