What fertilizer is best for kalanchoe? A detailed guide to the latest fertilizing methods

1. Fertilizing time

The root system of kalanchoe is not very developed, so its tolerance for fertilizer is poor; usually, applying a moderate amount of fertilizer is enough. When changing the soil, a small amount of base fertilizer can be applied. During the normal growing period, topdressing can be used, and during the flowering period some extra fertilizer is also needed.

2. Types of fertilizer

For base fertilizer, a slow-release fertilizer can be chosen, as it can take effect gradually. For topdressing during the growing period, foliar fertilizer can be used. In addition, during the flowering period, mainly phosphorus fertilizer is supplemented, such as potassium dihydrogen phosphate and so on.

3. Fertilizing methods

1. Slow-release fertilizer can be buried in the soil, so that it will gradually exert its own effect, and fertilizer burn generally will not occur. The foliar fertilizer used for topdressing can be sprayed directly on the surface of the leaves, making the leaves appear more glossy and better looking. When using potassium dihydrogen phosphate, attention needs to be paid to the concentration; it can be around one part per thousand.

2. The frequency of fertilizing also needs to be controlled. Soil can be changed about once every two years, and at this time slow-release fertilizer is applied. Foliar fertilizer can be used about once every two weeks. The potassium dihydrogen phosphate used during the flowering period is applied once a week until flowering.

4. Precautions

If the surrounding temperature is unsuitable, then do not fertilize. Specifically, when the temperature is higher than 30 degrees or lower than 5 degrees, it is not suitable to fertilize.
