The method of distinguishing male and female ginkgo trees is as follows:

1. Tree size.

The easiest way to identify a male or female ginkgo tree is to judge from the crown of the tree. Generally, the male ginkgo tree will be taller and straighter, and the branches will grow outward to a smaller extent and mostly grow straight upward. , in the shape of a triangle. The female ginkgo tree will be relatively short, with a larger opening angle of the branches, fewer branches, and a wider horizontal crown.

2. Bark color.

In addition to judging the male and female ginkgo trees from the size of the tree, you can also easily judge from the color of the tree. The bark of male ginkgo trees is darker, has deeper cracks, and is drier. The bark of the female ginkgo tree is lighter in color, the cracks are also shallow, and it is gray-white.

3. Leaves.

It is also easy to identify the male and female ginkgo trees from the ginkgo leaves. Generally, the color of the male ginkgo leaves is darker, and the crack in the middle is also deeper. The depth is generally two-thirds of the leaf, and vice versa. The female ginkgo leaves are shallower, and the crack in the middle is also very shallow, only a quarter of the leaf.

In addition, the male and female ginkgo trees can also be judged from the time when the leaves fall. The female ginkgo leaves turn yellow in autumn and fall earlier, while the male's invisible leaves turn yellow in autumn. It turns yellow later and leaves fall later.

4. Results.

Although male ginkgo trees also bloom, they bloom to pollinate female ginkgo trees. Because the growth of ginkgo trees is extremely slow, it usually takes more than 20 years after planting to bear fruit. Therefore, many people do not know whether the ginkgo trees they have planted for many years are male or female. This is because the ginkgo trees bear fruit too late.
