Pumpin pollenation? My neighbor discovered that he has two pumkin plants in his garden....

My neighbor discovered that he has two pumkin plants in his garden. He be told that it would not make pumpkins unless he rubbed the flowers from one to the other. Is this true? or what does he have to do for it to build pumpkins.
thanks
not true -the pollen is transferred via loop, bugs, and birds. each flower generally turns into a pumpkin. bees and other bugs pollinate. not rubbing flowers together
There are male flowers and female flowers. At first you will solitary get male flowers, as the vine get longer the females will start. The female flowers have a green bubble under the flower, whereas the male stem is straight. Watch your feminine flower, you will know it is going to open because the flower tip will start to colour. First morning it opens pinch a male flower, take it past its sell-by date the vine, strip the petals and carefuly rub the stamen (the orange thing inside the flower) onto the stamen (not sure if i.e. the correct term) of the female flower (its more bulbous looking). You can use a bunch of male flowers to manufacture sure but be careful not to damage the feminine. You can also use a paint brush or a q tip. After a few days the bulb under the female should start to correct colour and grow, if it's shriveling up the pollination didn't work. Don't worry you can get the subsequent one. By the spelling of neighbor I guess you are in the USA. Here in UK we enjoy not had much good weather so the insects, such as bees, enjoy not been so active and that`s why plants have not been instinctively pollinated which inevitably means you must pollinate the plant as described by the first two contributors to your question.

Make sure that you nurture and water your plants regularly as pumpkins need pretty a lot of water.
Answers:    Pumpkins have mannish and female flowers, so just impulsively rubbing flowers together won't always work. Female flowers will have for a while ball, almost like a mini pumpkin wannabe at the bottom, manly flowers don't. Sort of like people, the girl flowers enjoy "hips". You need to exchange pollen between the girls and boys. It's usually done by insects like bees, but you can do it if you resembling. It's hard to tell the difference between sundry squash vines as well- so it's entirely possible what you end up with may not be pumpkins. But righteous luck playing bee anyway.
Sometimes you do have to hand pollinate; especially sine the paucity of bees has occurred lately. You only just brush the pollen of the male flower onto the female one, the one beside the small swollen stem base; then tolerate nature take its course. I grow pumpkins every year I own not had to do anything they pollenate on there own and do simply fine. I have never of anything like that.
Don't you enjoy flies, and bees, and other flying things? Even earwigs can pollenate pumpkins. You shouldn't need to do anything. Let them grow. The insects will do their thing and you will bring back pumpkins.

Unless he's a pestacide freak. But don't be using pesticides.
no you dont i've growed pumpins be for you solely need one plant that is a honourable question but sorry i dont know
