Are cucumbers self pollinating?

Cucumbers are self-pollinating. Self-pollinating doesn't mean that they pollinate themselves, but it does mean that a single plant produces both male and female flowers.

Do all cucumbers need to be pollinated?

Most cucumber varieties, including all open-pollinated varieties require pollination. In Europe and North America thousands of bee hives are annually carried to cucumber fields just before flowering for this purpose. The flowers of these 'open field' varieties must be pollinated by bees to set fruits.

Why are my cucumbers blooming but no fruit?

The female flower cannot produce the pollen needed to cause the fruit to develop and is dependent upon insect (or human) pollinators to transport the pollen from the male flower. The male flowers begin forming before the female flowers form. So, it is possible to have cucumbers blooming, but not producing fruit.

Do cucumbers need 2 plants to pollinate?

Monoecious Cucumber Pollination

Such cucumber plants do not need another cultivar cucumber plant for pollination. They require bees, other insects or wind, however, to spread their pollen from their male flowers to their female flowers. In the absence of these aids, gardeners can turn to hand pollination.

Can I plant just one cucumber plant?

Monoecious cucumbers do not need more than one plant, since they produce both male and female flowers. Gynoecious cucumbers only have female flowers, so they need another plant with male flowers to produce fruit. Parthenocarpic cucumbers do not need more than one plant, since they produce fruit without pollination.

Can you manually pollinate cucumbers?

To hand-pollinate a cucumber, dip a paintbrush into the center of a male flower. Some gardeners use a cotton swab instead of a paintbrush. The pollen sticks to the bristles on the paintbrush just as it would stick to the hairs on a bee's body.
