My pumpkin plants are not producing pumpkins.?

Question

My plants have long vines,large leafs, and many flowers,but no pumpkins. The flowers open up and after a few days fall off. I have seen many bees in the flowers and I myself have put the pollen from one flower into another. I know that some flowers are supposed to be male and others female. Based on what I observe, they all seem to be male.

Answer 1

If your plants were pollinated, they may have aborted because of stress factors such as too much heat.

Poor pollination affects fruit set & even too much nitrogen can delay the setting of fruit on the vine. The most common is a mid summer heat wave. High day and night time temperatures will cause plant stress. The tiny pollinated fruit may abort as a result. A heat wave can also deter bees from their job, making hand pollination more important.. which is what you've done. Pollination will be more successful if several male flowers are used to pollinate one female flower. Pollination needs to be made to all segments of the female flower. Do this before 10 a.m. because pollination carried out at the end of the morning during warm weather has very little chance of success because the pollen will have heated up and fermented and will no longer be viable. At the bottom of the blossom of a female is a tiny vegetable or fruit (ovary). If the blossom is male there is nothing there. Here's a picture & instructions:

Make sure you don't water overhead early in the morning so the male flowers can have a chance to pollinate the female flowers.
Male flowers are short lived. They will open up before dawn and will close completely by mid-morning.The male flowers possess both pollen and nectar, the female flowers only nectar. If the plants are watered from overhead early in the day, that may prevent all further pollination for that day. Everything gets washed off of the short-lived male flowers. Replacement flowers do not open then until the following morning.

Too much shade or not enough light is another cause of poor fruit set. Most fruiting vegetables do best in full sun all day --- they need at least 6 to 8 hours of sunlight.
Extreme temperatures during flowering ( below 55 degrees or above 85 degrees), can reduce fruit set.
Good luck! Hope this helps.

This website has photos of male and female pumpkin blooms: http://www.hort.purdue.edu/ext/senior/vegetabl/pumpkin4.htm.

If your pumpkin plants seem to be producing all male flowers, the following may be the cause:
1. Young plants. If the plants are "adolescents", they produce mostly male flowers.
2. High temperature. After the weather cools, you will get female blossoms. Pumpkins do not grow as well in hot, humid weather and this is the vine's way of waiting until the climate is more suitable.
3. Too-fertile soil. Too much nitrogen (fertilizer) can cause mostly-male blooms.

You have seen bees pollinating the flowers, and you have pollinated them yourself. The situation may be one of the above. You may just have to be patient!

Answer 5

The male flowers are on a thiner, longer stalk. The female flower is shorter/closer to the vine and usually has a bulge at the base of the flower which will become the fruit. My guess is that if it is only putting out one kind of flower it is a hybrid issue with the plant.

Answer 7

They both are Perfect for your health. If you eat both, you're better off. But yea, I've choose fruits because they taste better.

Answer 8

It will depend on the fruit or veggie associated with a comparison. If perhaps you compare a farrenheit to a carrot, the carrot is the better of the two nutritional. When you compare an avocado to the carrot, then an avocado is better. The two the apple and avocado, are fruits.

Answer 9

just wait a bit must of the time the vine will put out male flowers way a head of the female flowers. this happens to insure plenty of male flowers are available when the female flowers are ready to bloom.

Answer 10

you can picked the male flowers and remove petels but not stamens and looking the female flowers and
you can pollination the female flowers and waiting get fruit pumpkins
