How to Propagate a Ginkgo Tree? A Detailed Guide to Common Propagation Methods
The ginkgo tree is a tall tree of the Ginkgo family. The seeds of the ginkgo tree, commonly known as white nuts, are a green health food, so the ginkgo tree is widely propagated as an economic crop. Today, the editor will introduce the propagation methods of the ginkgo tree.
1. Cuttings
Cuttings means cutting branches from a ginkgo tree that has already grown for many years and inserting them into the soil, so that the branches take root and sprout in the soil to form a new tree. Cuttings are further divided into hardwood cuttings and softwood cuttings. Hardwood cuttings are mostly used to cultivate large batches of trees for various commercial purposes, while softwood cuttings are used for home and personal planting. You can choose according to your own situation. Hardwood cuttings are suitable in spring. Select well-grown branches from a large tree and cut them into cuttings about 20 cm long. After cutting, rinse them clean with water, soak them in rooting powder, and then insert them into the soil. In about a month or so they will take root and sprout, after which normal care and management can be carried out. Softwood cuttings means cutting off softwood branches and inserting them into a container, changing the water every 3 days, until roots grow and then moving them into the soil.
2. Division
Division propagation is generally used for cultivating trees needed for urban greening, because ginkgo trees often produce suckers, especially trees around 15 years old. The method is to clear away the soil around the roots of the tree, use a relatively sharp tool to cut the suckers off the tree, and then plant them elsewhere for cultivation and management. This method generally can bear fruit earlier.
3. Grafting
Grafting is generally used for large-scale production of ginkgo nuts. The grafting time is usually in summer, but note that grafting cannot be done when the temperature is very high, especially at noon, and it also cannot be done on rainy days. The main method is to cut off a leaf from a well-developed branch, leaving only the petiole, and wrap the cut leaf joint with a wet cloth or put it in water. It is best to choose grafted seedlings as the grafting subject. After grafting, seal the joint with plastic wrap or similar film, and then carry out normal care and management. Generally, it will bear fruit in 6-7 years.
4. Sowing
Sowing is mainly used for building greenery and bonsai. Collect seeds in autumn, remove the outer skin of the seeds, dry the seeds in the sun, and sow in winter or spring. When sowing, place the seeds in dug trenches or holes at a depth of 3-4 cm, cover them with soil, and tread the soil firm and thick. After one year, the saplings can grow to about 30 cm, and then transplanting can begin. However, the drainage system of the sowing site must be good, and water must not accumulate, otherwise the saplings will be rotted.
The above are the propagation methods of the ginkgo tree compiled for you by the editor. Generally speaking, these four propagation methods are adopted. Have you learned them?
