Cultivation methods and precautions of Sophora japonica

1. Maintenance methods

1. Soil: Thick, fertile, and water-conserving soil is very suitable for the growth of Sophora japonica. Before planting, it should be disinfected with pesticides or exposed to sunlight.

2. Water: It likes an environment with sufficient water. When watering, you should water it thoroughly to ensure that it has sufficient water.

3. Nutrients: You can use chicken, duck, pig manure, or human feces. Spread the manure flat and let it dry, then spread it evenly on the soil. But don't get too close to the roots of the tree, as this may cause root burns.

4. Light: Sophora japonica likes light. It likes gentle sunlight. Sufficient light will make its branches and leaves green, thick and beautiful. However, it does not like too strong direct sunlight, which will cause damage to its branches and leaves, so appropriate shade is also necessary.

2. Breeding techniques

1. Pruning: It is easy for dead branches and rotten leaves to occur during the growth period. They should be pruned in time to prevent the dead branches and rotten leaves from containing pathogens and infecting other healthy branches. Therefore, pruning is also very important.

2. Reproduction: The cutting method is often used for reproduction. Cut a small piece of strong branches and soak it in water to absorb more water. Then plant the cuttings in the nursery bed, and you will see small sprouts growing in about a week. At this time, it is necessary to fertilize, sterilize and protect it, and then transplant it into the soil when it grows a little bigger.

3. Problem diagnosis and treatment

1. Skin rot: The disease of Sophora japonica is skin rot, and the symptom is the occurrence of spots. Then small black spots of pathogens begin to appear, which are very harmful to the Sophora japonica. Some carbendazim should be diluted and sprayed to solve the problem.

2. Sophora japonica scale: This pest has a serious impact on its growth. It will suck the sap from the branches, which will cause the plant to become weak and withered in the long run. To kill insects, you can dilute avermectin and spray it twice a week.

IV. Other issues

1. How to spend the winter: Water it once in winter to ensure its water supply throughout the winter and prevent frostbite in cold weather.

2. Can it be exposed to rain: Sophora japonica can be exposed to rain. When it rains, the rain will wash its branches and leaves, making it look green and colorful, and very ornamental.
