Brett, Are you using bought seeds or saving seeds from pumpkins? If you have bought seeds, it might be worth contacting the supplier and telling them about your problem. Otherwise, if you saved seeds, see the answer to Jean's query.

Ray, your pumpkins are falling off early because they are not fertilised. You may need to go around with a paintbrush and transfer pollen from the male flowers to the female. Check the comment from Jaci to identify which is which.

Jean, you may be lucky. If you had an organic pumpkin it will probably produce both male and female flowers but if it was a F1 hybrid then its seeds will produce sterile plants. Check the flowers for possible female ones (see comment from Jaci above).

I also have seeds germinating from my compost and have at times so much produce have taken great joy in giving them away and hearing about the joyous results. I am out most mornings 2 hours after sunrise when the male stamen is all fluffy with pollen and the female has ants crawling around inside. I pollinate myself by gently picking and trimming the male flower because if I leave it to mother nature my crop is very small. I usually use 2 or 3 male flowers on one female just in case. Recent rains have not been helpful for flowers at all but 1 week later flowers are appearing and just this morning I watched a bee laden with pollen flying from flower to flower. It was so laden it had trouble flying. I love mother nature she is the best for people like me.
