How to fertilize Kalanchoe, what fertilizer is best

1. Fertilization time

The root system of Kalanchoe is not well developed, so it has poor tolerance to fertilizer. Just apply an appropriate amount of fertilizer on a normal day. When changing the soil, you can use a little base fertilizer. During the normal growth period, you can apply top dressing, and during the flowering period, you need to use additional fertilizer.

2. Fertilizer Types

You can choose a slow-release fertilizer as the base fertilizer, which can take effect slowly. Foliar fertilizer can be used as topdressing during the growth period. In addition, during the flowering period, phosphorus fertilizer should be supplemented, such as potassium dihydrogen phosphate, etc.

3. Fertilization method

1. Slow-release fertilizer can be buried in the soil, so that it will slowly exert its own effects and generally no fertilizer damage will occur. The foliar fertilizer used for top dressing can be sprayed directly on the surface of the leaves to make the leaves appear more shiny and better looking. When using potassium dihydrogen phosphate, you need to pay attention to the concentration, which should be around one thousandth.

2. The frequency of fertilization also needs to be controlled. The soil can be changed about once every two years, at which time a slow-release fertilizer should be applied. Foliar fertilizer can be applied once every two weeks. During the flowering period, potassium dihydrogen phosphate is used once a week until flowering.

IV. Precautions

If the surrounding temperature is not suitable, then do not apply fertilizer. Specifically, if the temperature is above 30 degrees or below 5 degrees, it is not suitable for fertilization.
