4. Other reproduction

Ginkgo branches do not have high time requirements, but they are generally chosen in spring. Since only trees that are more than 15 years old will sprout, for new trees, rooting can be promoted by girdling the root tillers before planting. After girdling, you need to cultivate the soil. New roots will usually grow in about a month. Separate the plant with root tillers from the parent plant and plant it in a place with good air circulation and sufficient light. Water it once after planting.

1. Time for division

There is no fixed requirement for the time for division of ginkgo. This plant has strong adaptability and can grow healthily after division at all stages. Under normal circumstances, it is mostly done in spring, when the temperature is warmer, which allows the child plants to develop better.

2. Promote new tillers

Usually only trees that are about 15 years old will sprout tillers. For some trees that have not sprouted tillers, certain methods can be used to encourage them to grow new tillers. First, girdle the roots and stems. The girdling time is usually from July to August. Then, earth is added to cover the girdling wounds. Generally, it only takes 1 month for the girdling areas to grow. New roots have emerged.

3. Planting by divisions

For plants that have grown root tillers, they need to be cut and separated from the parent plant before planting. Choose a place with good air circulation, sufficient light, and high ground to help the plant grow. After planting, water appropriately, but don’t water too much. It will take some time for the plant to adapt to the new environment, and its ability to absorb water is not strong enough. Watering too much can easily affect root respiration.

IV. Other reproduction

Ginkgo There are many ways to propagate trees. In addition to division, there are three methods that can be used: sowing, cuttings, and grafting. Sowing is mostly done in spring and needs to be germinated first and then planted into the soil. Cuttings are divided into hard branch cuttings and twig cuttings. The bottoms are dipped in rooting powder and then inserted into the seedbed. After the roots grow, they are transplanted. Grafting propagation is more common, and can be cleft grafting, cut grafting, skin grafting or bud grafting.
