1, soil requirements

Yushu should be planted in loose and fertile soil with good drainage. Peat soil and humus soil contain a lot of organic matter, and peat soil is very breathable, which is very suitable for planting Yushu. It is best to use the same amount of humus soil, peat soil and vermiculite to make Yushu grow more vigorously.

2, watering requirements

In the cultivation methods and precautions of Yushu, water every 3-4 days in the spring and autumn growth period and every 65,438+0-2 days when the temperature is high in summer. It is more suitable in the morning and evening. In the case of low temperature and slow growth of Yushu in winter, it is only necessary to water it once every 65,438+0-2 weeks.

3. Lighting temperature

Yushu likes a warmer growing environment, and the most suitable growing temperature is between 20℃ and 30℃. When it is hot in summer, it should be maintained in the shade, especially when the temperature exceeds 35℃, it must be cooled down. In spring and autumn, it can be maintained in sunny places. In winter, the temperature is low, so you should get as much sunshine as possible to ensure that the temperature is not lower than 10℃.

4, fertilization requirements

Yushu grows rapidly and has a great demand for nutrients, especially in the spring and autumn period. Generally, fertilizer is applied once every two weeks, and decomposed organic fertilizer or cake fertilizer can be used. If it is a compound fertilizer, mainly nitrogen fertilizer can promote Yushu to grow more green leaves, and the leaves are still very lush.

5. Preventive measures

(1) pruning. Yushu pruning can be done according to everyone's hobbies. If the crown is round and plump, the long branches will be cut off when pruning, which will make the crowded branches overlap too much, so that the external crown of the plant is complete and the internal branches are properly spaced. If the tree is long, the old trunk is thick and the crown is not round, it can be trimmed or stump bonsai, and some branches and leaves can be cut off according to the needs of modeling.

(2) change pots. Change pots every spring. When changing pots every year or putting houses in autumn, attention should be paid to shaping and pruning to make the plant shape more elegant.
