1、 Breeding environment

1. Soil: loose and fertile soil is needed. In addition, the requirement for pH is slightly acidic, which is conducive to root development. It can be prepared with rotten leaf soil and garden soil in a ratio of two to one, and then mixed with some base fertilizer

2. Light: plant trees like light, but fear strong light. It is usually placed in a place with scattered light, and can receive more light from September. In October, it can be fully illuminated to promote the development of flower buds

3. Temperature: usually about 15 degrees. In winter, it is better to be around 10 ℃ and not lower than 0 ℃. Not higher than 30 ℃ in summer

4. Watering: the amount of watering should be appropriate and no ponding is allowed. In summer, water can be sprayed once in the morning and once in the evening. It should be reduced appropriately from the end of autumn. But it can't stop in winter. This is its flowering time

5. Fertilization: autumn and later is its growth period and flowering period. Liquid fertilizer needs to be added every week and ten days. Nitrogen fertilizer is mainly used in the early stage, and phosphorus fertilizer is added in the later stage

2、 Pest control

Seedlings are prone to "sudden onset disease", which can be treated with dixone. Pests also occur from time to time and should be prevented and controlled in time

3、 Regular pruning

In addition to cutting off messy, diseased and dead branches at ordinary times, the flowering period is more important. If you want to collect seeds, cut off some of the flower branches during flowering. Cut off the dead flowers in time after flowering

4、 Change basin regularly

Generally, it is changed once a year. If the soil is good, it can be changed once every two years. After pruning and then changing, a small part of the old soil can be retained
