Cultivation methods and precautions of Gleditsia sinensis

1. Maintenance methods

1. Soil: There are no requirements for soil quality, and soapberry can be grown in general soil. If you want to plant it yourself, you can choose sandy loam, which is fertile, breathable, and has good drainage, making it very suitable for its growth.

2. Water: Soapberry is very drought-resistant because its roots grow very deep and can store water on their own. Normally, you should water the plants every 30 days or so, and water them thoroughly, but do not allow water to accumulate.

3. Nutrients: Scientific fertilization is very important. During the growth period, it is best to use decomposed and fermented cow and horse manure. The fertilizer should be spread evenly so that the soapberry can fully absorb it.

4. Light: Sophora japonica has a certain degree of shade tolerance and is a light-loving plant. It is suitable for sufficient sunlight, but it does not like strong direct sunlight, which will cause sunburn on its branches and leaves.

2. Breeding techniques

1. Pruning: After planting, pruning should be strengthened to cultivate the growth of the trunk. When pruning, the height of the trunk and the roundness of the crown should be the main focus. Some dead branches and wilted buds should also be pruned off, which can promote the growth of side branches and make the shape of the crown round.

2. Reproduction: Sowing is usually used for propagation. Select old trees between 30 and 80 years old and produce plump seeds. Dry it in the sun, then beat it to remove the peel and soak it in water for two days and two nights. Then take them out and place them in wet sand for germination and storage. When the seeds crack and reveal the white throat in mid-March, they can be planted.

3. Problem diagnosis and treatment

1. Sooty mold disease: If the branches of the tree crown are too dense and there is no ventilation and light inside, it is prone to sooty mold disease. At this time, you should spray the branches and leaves with diluted Horlicks to control the spread of the disease. Spraying once a week, about three times will be enough.

2. Gleditsia sinensis: A common insect pest is Gleditsia sinensis, which is very harmful to it. It can be prevented and controlled by diluting hypertonic fenoxycarb emulsifiable concentrate and spraying it.

IV. Other issues

1. How to survive the winter: Water it once before winter comes, so that it will not be frozen in the cold winter. Wait until early spring to water it with thawing water, which will promote the growth of new branches.

2. Can it be exposed to rain: Yes, it can be exposed to rain, but the water should be drained in time after the rain to avoid affecting its normal growth.
