how to pollinate a grapevine

Grape vine leaves need sunlight to transfer the sugar content to the grapes, but the fruits do not need sunlight to grow. If the female caps are off the flowers and the male flowers are blooming at the same time, you can clip off a male bloom and tap it on the female flowers to cross-pollinate the two.

How are grape vines pollinated?

Pollination is by wind and insects, such as small flies. Most cultivated grapes have “perfect flowers,” with a normal ovary and pistil and fully developed, upright anthers. ... Each flower in a cluster of a perfect-flowered or a female-flowered variety can “set” and become a single grape.

Do you need two grape vines to pollinate?

Most grapes are self-fruitful, so cross pollination is seldom necessary. Brighton is an exception, and one of the few common varieties that is not self-pollinating, so it needs a partner to bear fruit. Nursery catalogs will usually state when a pollinator is needed for any cultivar.

How do you get a grape vine to produce fruit?

Are grape vines pollinated by bees?

Bees aren't needed to pollinate grapes (the vines are wind-pollinated), but Carolyn Brown, beekeeper at Frey Vineyards, says that many of the cover crops like mustard and clover that are planted between the vines require bee pollination. These cover crops make excellent forage for the bees and yield tasty honey.
