If you plant pumpkins in mid-May or early June, you will probably start blooming to see in July. But for the beginner gardener pumpkin, these first flowers bear disappointment. Pumpkin vines have separate male and female flowers, and the fruitless male flowers appear first. You have two options when your flowers start to appear: Let pollination of bees or the do-it-yourself approach.
The first flowers on a pumpkin vine appear, are the male flowers. They show one or two weeks prior to start female flowers attracts pollinators such as bees. Male flowers are large and extend from the vine on thin stems. Their centers contain pollen-bearing stamens. The stamens are seen usually large and easy. They have a yellow pollen ball rests on the top of a white filament.
Female flowers are easy to spot. They are close to the vine on short stalks. Between the vines and the flower, you will see a small round ball. This is the ovary, and when the flower pollinated, Wilts, and she dies and the ovary grows into a pumpkin. The vine produces more male flowers than female, because this increases the chance of pollination.
Bees usually carry out natural pollination of squash blossoms. Male flowers produce nectar with pollen, to attract them. Women make up the double nectar of bees men so be sure to visit them also. If your pumpkins are not fertilized, you may not have the bees in your area. Or could you or someone else be in the neighborhood of pesticides in your garden. Pesticides are used to kill aphids and other common garden pests also kill bees, limiting the possibility of pollination.
If do not nature, is the task that you have to pollinate by hand. Pumpkin flower clock in the morning and close at noon. It is best early in the morning to pollinate as possible, just as soon as your flowers open. Once they are closed, they are not open, so you have to be ready. Carefully choose the male flower and pull the petals. Brush the stamens to the center of the female flower, which got out to make sure all parts of pollen on the stigma of the female flower. Then wait and see. If pollination is unsuccessful, the ovary will shrink and die in a few days. If so, your little pumpkin will start to grow.
