How do I pollinate my cucumbers?
This well-pollinated cucumber plant is growing a new cucumber. The fruit comes from the female flower, pollinated by pollen transferred from a male flower, like the bright yellow one above. Ideally, pollen is transferred by bees, but if not, hand-pollination is an option.
Hand pollination, also known as mechanical pollination is a technique that can be used to pollinate plants when natural or open pollination is either undesirable or insufficient. This method of pollination is done by manually transferring pollen from the stamen of one plant to the pistil of another.
- Cucumber plants require insects, like bees, for pollination. The plant grows both male and female flowers on the same plant. While both flowers are the same color and similar in appearance, there some differences that you can look for to help identify which flowers are male and which are female.
- When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants.
- Some veggie plants, like tomatoes and peppers, are self-pollinating, but others such as zucchini, pumpkins, and other vine crops produce both male and female flowers on the same plant. During these stressful times, you may need to hand pollinate your pepper plants.
Fruit set is much higher with human pollinators – every flower is fully pollinated and can become fruit. A person can pollinate 5–10 trees a day, depending on the size of the trees. In 2010, farmers paid their human pollinators US $12–19/person/day, if they pay them at all.

- All pollinators, both insects and vertebrates, visit flowers to get something out of them for themselves. This may be nectar, pollen or both. During this visit pollen lands on the body, after which it may accidentally land on the stigma of either the same flower or another flower. This is also true for the bumble bee.
- Strawberries are self-fertile. Strawberry plants will pollinate themselves, but they usually need the assistance of wind or pollinators, such as bees, to do the work of transferring the pollen from the stamens, the male parts of the flowers, to the stigma, the female part of the flower.
Artificial pollination is the process of humans pollinating crops instead of bees. Almond crops in California are often pollinated through pollen dusting, but the process is inefficient and costly. Hand pollination uses humans as honeybees, directly applying pollen from one flower to another.
- Because potatoes and tomatoes have similar flowers and pollination, potatoes are self-pollinated, which means they have the male and female flowers on one plant. Pollination can occur from wind and from insects. However, for potatoes, this pollination does not have to take place to form the underground tubers.
- Use the brush or swab to gently swirl around the stamen of the male flower. Carefully swirl the pollen collected on the brush onto the stigma of the female flower. Touch all surfaces around the middle of the female flower. Collect pollen from multiple male flowers for each female flower on the plant.
- Pollination is the process by which pollen is transferred to the female reproductive organs of a plant, thereby enabling fertilization to take place. Like all living organisms, seed plants have a single major goal: to pass their genetic information on to the next generation.
