FAQ: How To Pollinate Tomatoes In A Greenhouse?

How do you pollinate in a greenhouse?

If you have a small greenhouse, manually pollinating plants is cost-effective and takes little time. Gently shaking plants or tapping flowers releases pollen from male flower parts to female structures. Some plants, such as squash, have separate male and female flowers so pollen must be transferred between blossoms.

Do greenhouse tomatoes need pollinating?

Tomatoes can be fully pollinated by self- or cross-pollen, and cross-pollination does not appear to improve quality. In addition, honey bees are not capable of buzz pollination. The commercial bumble bee industry is now fully established in Ontario, especially for pollination of greenhouse tomatoes.

Are tomatoes self-pollinating?

Tomatoes are self-fertile, which means each flower can pollinate itself. Nevertheless, the presence of bees and/or wind dramatically improves pollination by nudging the flowers just enough to help dislodge the pollen from the stamens.

How do you pollinate tomatoes indoors?

Because tomatoes are self-pollinating, they do not require assistance from insects or gardeners, but you can help the pollination process along by gently shaking the stems every day or by placing a small oscillating fan in the area to mimic the wind.

Removing some of the leaves will help the sun reach the tomatoes, and they will ripen faster. The plant will focus more energy on growing the tomatoes if you remove some of the leaves too.
