Why in the same campus, some ginkgo leaves turn yellow, and some are still green?

Ginkgo biloba leaves can't see the leeward side of the sun is yellow, so some invisible leaves are yellow in late autumn and some are green. Ginkgo biloba turns yellow at 10- 1 1. By June 65438+ 10, its leaf edge will turn yellow, and then the whole leaf will appear very beautiful golden yellow, but it won't last long, and it will start to wither in the late period of June 1 1.

Growth habit

Ginkgo tree has a long initial growth time and strong germination. Ginkgo trees are divided into male plants and female plants. Male plants do not bear fruit, and female plants generally begin to bear fruit after 20 years.

Ginkgo trees generally begin to sprout and spread leaves in March-April, bloom in April-May, mature in September-65438+ 10, and begin to shed leaves after 65438+10. Seedlings, transplanted seedlings or tillers are often grafted in the cultivation area, which can blossom and bear fruit 8- 10 years in advance (seedlings usually start to bear seeds after 20 years). Ginkgo biloba cultivated everywhere is hundreds or thousands of years old.
