1. Pruning time

2. Pruning method

Ginkgo pruning is generally done in summer and winter, with heavy pruning in winter and light pruning in summer. There are many methods of pruning. First, annual branches need to be shortened to promote the development of new branches. Secondly, the areas that are too dense should be appropriately thinned out, and the long branches and thin branches should be cut off, and the buds should be wiped appropriately. For old branches, they need to be retracted by half or two-thirds to allow them to rejuvenate. In addition, topping and circumcision are required.

1. Pruning time

The pruning time of Ginkgo is generally carried out in summer and winter. In winter, the plant is in a dormant state, so pruning should be heavy, so that the stored nutrients can be concentrated, which will help the growth of the second year. The growth of new shoots. In the Xi family, pruning should be light, and it mainly plays a supporting role to control the growth of the plants. Too much pruning will affect photosynthesis.

2. Pruning method

1 Short pruning: Short pruning is a very common pruning method. It mainly targets annual branches and cuts them shorter to promote the growth of branches and the development of side branches. Usually, the length of pruning is one-third, and 2-3 long branches will sprout at the cutting edge. The new shoots can grow to about 30-50 cm in the same year.

2. Thinning: If the top of the Ginkgo tree is too dense , cross branches and overlapping branches are clustered, which affects the internal ventilation and light transmission, so it needs to be appropriately thinned out. Thinning pruning should cut off leggy branches, as well as thin and drooping branches. When they sprout, wipe out the buds with bad direction, which can also have a preventive effect.

3. Retraction: Retraction is similar to pruning, except that it mainly targets old branches, and the pruning force is stronger. Retraction generally only retains half of the length of the original branch. For some thicker branches, only one-third can be cut. It should be noted that the diameter of the cut should not exceed 5 cm.

4. Topping: For any plant, topping is important It is very necessary, in addition to controlling the height of the plant, it can also promote branch growth. Potted ginkgo needs to be pinched to prevent it from continuing to grow upward, which is very helpful in controlling the shape of the tree. Generally, the terminal buds are removed when the branches reach 15 cm to promote secondary growth of the branches.

5. Ring cutting: Use a knife to cut off the cortex of the ginkgo tree branches to a depth that reaches the xylem, which can promote its flowering and fruiting. However, it is generally only used for branches that grow vigorously and are strong and strong. Although girdling weak branches can also promote growth, due to limited nutrients, the results are often not as good as thick branches.
