When do ginkgo leaves generally turn yellow and fall in the north and south?

The ginkgo tree is a tree with ornamental and economic value, and it also has certain medicinal value. When the ginkgo leaves turn yellow, is it not a lovely thing to invite a few friends to enjoy the scenery and catch up on old times? Here we will tell you when ginkgo leaves generally turn yellow in the north and south of China, and in which month they wither and fall?

1. When do ginkgo leaves generally turn yellow in the north and south of China?

According to data from the gymnosperm division, ginkgo tree leaves generally all turn yellow around the end of October to early November, and the most suitable viewing period is around November 10.

2. In which month do ginkgo leaves wither and fall?

Ginkgo leaves begin to wither and fall in late November. So friends who want to enjoy the leaves should seize the time.

1. In October, the edges of ginkgo leaves have already begun to turn yellow, and gradually the leaves will turn golden yellow, looking especially beautiful.

2. If there is no strong wind during this period, the golden color will continue until mid-to-early November,

3. Then the northwest wind blows in the north, and the leaves begin to drift down one after another, leaving the ground covered in gold as well.

4. After passing through the cold winter, it is generally not until around May of the following year that tender green buds begin to sprout.

3. What ecological functions does ginkgo have?

1. Ginkgo is resistant to pests and diseases and is widely recognized as a pollution-free tree species, making it the most ideal tree species for ornamental greening. The greening effect of ginkgo trees is very good, but the effect is slow to show. Small trees need to be planted for 2 years before they can have a good effect. After large trees are planted, they need 3-5 years of recovery time before they can display their beautiful function.

2. Ginkgo can purify the air and has functions such as resistance to pollution, smoke and dust. It can naturally purify the air, reduce the content of suspended particles in the atmosphere, and improve air quality. Ginkgo has effects such as conserving water sources, preventing wind and fixing sand, and maintaining soil and water. In areas where forests have been cut down, soil erosion has occurred, and wind-sand erosion is present, ginkgo shelter forest areas, shelter belts, roadside protection forests, bank protection forests, beach protection forests, and sand-fixation forests are planted to maintain soil and water and improve the ecological environment.

3. Ginkgo has the function of killing crop pests and diseases, and is especially effective against cotton pests, spider mites, peach aphids, and striped stem borers. Planting ginkgo around agricultural areas serves as a natural enemy of crop pests to protect crops.

4. Ginkgo trees have the special function of being warm in winter and cool in summer. In midsummer, when the palm touches the ginkgo trunk, it feels ice-cold, while touching other tree trunks (willow) makes the palm feel hot. Creating ginkgo forest areas and ginkgo forest belts on a large scale forms a local microclimate, which has a good effect on regulating temperature and improving the microclimate for farmland and residential areas.
