1. Soil: Potted red fruits can be made by mixing 5 parts of humus soil, 3 parts of garden soil and 2 parts of sandy soil, and adding a small amount of phosphorus and potassium fertilizers such as calcium superphosphate and bone meal.

2. Fertilization: Red fruits like fertilizer, but they don't like thick fertilizer. Thin fertilizer should be applied frequently, and the decomposed thin liquid fertilizer of 1 times can be applied every 10 ~ 15 days. Nitrogen fertilizer is the main fertilizer in the young tree stage or bamboo shoot drawing stage, and phosphorus and potassium fertilizer are applied in other stages.

3. Lighting: Red fruits should be placed in a sunny and well-ventilated place outdoors during the growing season, and should be properly protected from light in summer.

4. Water: During the growing period, always water the red fruits, don't dry the pot soil, and often spray water on the plants and the surrounding environment to increase the air humidity.

5. Pruning: Red fruits are resistant to pruning and can be pruned and reshaped according to different tree types. During the growth period, useless buds can be erased at any time, and the buds can be picked at the right time to keep the plant shape perfect.
