Maintenance method of Sophora japonica

1, substrate selection: when raising Sophora japonica, it is best to choose deep soil with good drainage. Generally, calcareous, neutral and acidic soils can grow. If the soil is too dry, it will easily lead to poor growth, even on barren land.

2. Lighting management: the growth is best when the lighting is sufficient, and the lack of lighting will affect the growth. When the light is strong, it is easy to get sunburned. Plants can grow in dark environment, but they should be placed outdoors regularly for easy recovery and appreciation.

3. Temperature management: the suitable temperature for its growth is between 15 and 30 degrees Celsius. When it is hot in summer, it will enter a semi-dormant state, and the plants should be transplanted to a cool and ventilated place. It likes dry and cold climate, and can also adapt to high temperature and high humidity environment.

4. Water management: the principle of "wet and dry" should be followed when watering. During the growing period, the soil in the basin should be kept moist, but there should be no water in the basin, otherwise it will die easily. Keep watering twice a day in summer, control watering in winter or rainy days in late autumn, and less watering in winter is good for winter.

5. Preventive measures: water less in winter to avoid frostbite. Sow in sunny, fertile and loose places with good drainage, dig deep into the soil and add base fertilizer. It can be propagated by sowing or by tillering.
