1. When planting orange trees, sandy loam or sandy soil with high humus content can be selected, and a certain amount of decomposed organic fertilizer can be added to improve its fertility and maintain its normal growth. In addition, in order to better stretch the roots of citrus, it is necessary to choose a large-diameter sand bowl or clay pot.

When watering orange trees, we should control them well. You can't water too much at a time, depending on the soil conditions, once a day in summer, once a day in spring and autumn, once every three to four days in winter, and the water can't be too much and too dry.

3. Fertilization should adhere to the principle of "diligent application and thin application", and the decomposed liquid fertilizer should be applied once before the orange tree blooms, and then every 7~ 10 days, mainly to increase the yield. In the early stage of orange tree growth, in order to increase soil fertility, some cake fertilizer must be applied to the basin soil. After entering autumn, we should gradually reduce the amount of fertilization and strictly control the amount of fertilization.
