Q.Pumpkins
I had a pumpkin vine start voluntarily from a pumpkin we put in the backyard last fall. It has grown quite large and has had numerous blossoms. But none of the blossoms have produced pumpkin fruit. What should I do to get pumpkins on my vine?
You may be just getting male blossoms early on. It is the female blossoms that are the ones that will turn into fruit. This article will help you determine the male from the female:

If you are seeing female blossoms falling off, you may have a pollination problem and it would be best to hand pollinate. This article will help you with that:
