Why are the flowers fall off?

Hello, I will not even try to pronounce your name; I will call you Tom. Where are you located, Tom?

Pumpkins have male flowers and female flowers.
At the base of the female flower you will see a tiny bulge that will become the fruit/pumpkin.
Male flowers last only a few days...the female flower will stay open only for a day or two.
It is up the the pollinators such as bees to transfer the pollen from one flower to the other at the optimum time.

Sometimes there are lots of male flowers and hardly any female flowers; this is normal.

If you have planted enough seeds you can hope to have successful pollination. You can hand pollinate to increase you chance of having fruit.

Thank you, Ithink i'm in trouble a friend gave me one plant, it must be a male.However,I am. Female please call me. T and also e mail is [email protected] thanks! T

Welcome to All Things Plants, T @Tomcikustoniomcikus !

I agree with what Greene said, but fortunately the plants aren't either male or female... they have both types of flowers on the same plant. Usually the male flowers will open first, then some female ones will start -- which can be identified by the small pumpkin/squash/zucchini just below the flower.

Here's a photo of an interesting double golden zucchini that I had last year, showing the unopened flowers on the end...

Oops, guess I will call you "T" and not Tom.
It's not a good idea to include your email address in a public post; please consider using the 'edit' in the lower right corner.

One plant has both male and female flowers; having more than one plant just increases the odds of getting fruit. If a neighbor has a similar plant the bees will find it and your plant can get pollinated.
