A Detailed Guide to Four Propagation Methods for Ginkgo Trees
Ginkgo is a green plant now commonly seen in cities. Its growth cycle is especially slow. The editor has a ginkgo tree at the door of their home that has already grown for 20 years, and its trunk can still be held with two hands. Today, what the editor brings to everyone is the propagation methods for ginkgo.
1. Cuttings
Cuttings means cutting branches from a ginkgo tree that has grown for many years and inserting them into 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 quantities of trees for various commercial uses, while softwood cuttings are used for home and individual planting. Hardwood cuttings are suitable in spring. Select relatively well-grown branches from a large tree and cut them into cuttings about 20 cm long. After cutting, rinse them clean with water and then soak them in ABT rooting powder. Then insert them into the soil, and in about a month or so they will take root and sprout. Then carry out normal care and management. Softwood cuttings means cutting off soft branches and inserting them into a container, changing the water every 3 days, until roots grow and then moving them into soil.
2. Division
Division propagation is generally used to cultivate what is needed for urban greening, because ginkgo trees often produce suckers, especially trees around 15 years old. The method is to scrape the soil around the tree roots clean, use a relatively sharp tool to cut the sucker shoots down from the tree, and then plant them in other places for cultivation and management. This method can generally bring fruiting 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 is also not suitable 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 cutting seedlings as the grafting target. After grafting, seal the joint with plastic wrap or other film cloth, and then carry out normal care and management. It generally bears fruit in 6-7 years.
4. Sowing ⟧11⟧Sowing is mainly used for building greenery and bonsai. Collect seeds in autumn, remove the outer seed coat, dry the seeds in the sun, and sow in winter or spring. When sowing, put the seeds into dug furrows or holes at a depth of 3-4 cm, cover them with soil, and press 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 propagation methods for ginkgo are roughly the above four. As for which method is better, it still depends on your planting direction. If you want to sell trees, then use the cutting method, and it should be hardwood cuttings. If the main purpose is to produce fruit, then use the grafting method. The four methods vary from person to person. I hope these can help you.
