1、 Fertilization time

The root system of Changshou flower is not very developed, so its tolerance to fertilizer is not good. It can be fertilized appropriately at ordinary times. When changing soil, you can use an appropriate amount of base fertilizer. In normal growth period, topdressing can be used, and some additional fertilizer must be used in flowering period

2、 Fertilizer type

Slow release fertilizer can be selected as base fertilizer, which can play a role slowly. Foliar fertilizer can be used for topdressing in the growth period. In addition, phosphorus fertilizer, such as potassium dihydrogen phosphate, is mainly supplemented during the flowering period

3、 Fertilization method

1. Slow release fertilizer can be buried in the soil, so that it will slowly play its own effect, and generally there will be no fertilizer damage. The foliar fertilizer used in topdressing can be directly sprayed on the surface of the leaves to make the leaves look more shiny and better. When using potassium dihydrogen phosphate, pay attention to the concentration, which can be about one thousandth

2. The frequency of fertilization also needs to be controlled. The soil can be changed once every two years, and slow-release fertilizer can be applied at this time. Foliar fertilizer can be used once every two weeks. Potassium dihydrogen phosphate used in flowering period is once a week until flowering

4、 Precautions

If the surrounding temperature is not suitable, do not apply fertilizer. Specifically, if the temperature is higher than 30 degrees or lower than 5 degrees, it is not suitable for fertilization
