Ginkgo Tree Pollination Information

Ginkgo trees, also known as Ginkgo biloba, are dioecious, meaning there are separate male and female trees. The male trees produce pollen cones, while the female trees produce ovules that can develop into seeds.

Pollination Process

During the spring, male ginkgo trees release pollen into the air. The wind carries the pollen to the female trees where fertilization occurs. Once fertilized, the female trees produce seeds enclosed in a fleshy outer layer known as the sarcotesta.

Role of Insects

While ginkgo trees primarily rely on wind pollination, insects such as beetles and flies may also play a role in pollinating these trees. These insects are attracted to the foul-smelling fruit produced by the female trees and may inadvertently transfer pollen between trees.

Pollination Timing

Ginkgo trees typically bloom in late spring. It is important for male and female trees to be in close proximity for successful pollination to occur. Planting both male and female trees in urban or residential areas can help ensure proper pollination.

Ginkgo trees are unique and beautiful addition to any landscape. Here are some tips on how to plant and care for them:

Planting:

• Choose a sunny location with well-draining soil.

• Place the tree in the hole and backfill with soil, ensuring the tree is at the same level as it was in the container.
• Water the tree thoroughly after planting.

Care:

• Water ginkgo trees regularly, especially during dry periods.
• Apply a layer of mulch around the base of the tree to retain moisture.
