The main results are as follows: 1. The preparation of basin soil: the slightly acidic soil with loose night incense, good drainage and rich mechanism. The pot soil is generally made of peat soil or rotten leaf soil with 3 parts of coarse river mud and 2 parts of coarse river mud and a small amount of farm manure. When potted, the bottom is about 1 to 5 deeply filled with broken bricks in shape to facilitate basin drainage, and the upper part is cultivated with mixed basin soil.

2. Suitable environment: potted night incense requires well-ventilated environmental conditions. From the beginning of May to the end of September, it is suitable to put sufficient sunshine in the hospital or maintenance on the balcony. Although it likes sufficient sunshine, it should avoid hot sun exposure at noon in summer.

3. Fertilization management: in the process of its growth, liquid fertilizer should be applied every 10 to 15 days, and thin liquid fertilizer should be applied every half a month since late April, which can ensure continuous flowering from the middle of May. If you can apply high-efficiency humic acid liquid fertilizer such as Chunquan 883 or Huimanfeng, the effect will be better.

4. Water management: the summer is the peak growing season, and the basin soil must be kept moist regularly except for sufficient fertilizer, and water should be watered twice a day if necessary. If it is a seedling, it should be sprayed to the leaves once or twice a day.

After changing the basin, you should keep the soil moist, but there can be no stagnant water in the basin. If you find that the tender leaves droop slightly after changing the basin, you should water them in time.

7. adjust plant shape: scaffolding should be set up in cultivation and management, plants should be topped in time to promote more branches, residual pedicels should be cut off in time after blooming, fertilizer should be added, withered branches and overdense branches should be cut off after flower fade, and the overgrown branches should be truncated.
