How to fertilize azalea, what fertilizer is best

1. Fertilization time

Rhododendron is a plant that likes fertilizer, so its maintenance requires relatively high fertilization requirements. Fertilization can be divided into two categories: one is base fertilizer, which is used when planting; the other is top dressing, which is used when it grows faster.

2. Types of Fertilization

The base fertilizer used can be some solid fertilizer, such as animal manure. In addition to the liquid fertilizers usually used, you can also use some foliar fertilizers as top dressing.

3. Fertilization method

1. The application of base fertilizer is relatively simple. After the soil for planting is prepared, you can directly mix it in. It needs to be mixed evenly. As for liquid fertilizer and foliar fertilizer, their application is relatively troublesome. They need to be diluted before use, and the concentration cannot be too high.

2. Another thing is the frequency of fertilization, which can be determined based on the volume of the plant. If it is in the seedling stage, then the fertilizer requirements are not too high and it can be fertilized once a month or so. If the plant is already mature and relatively large, the frequency can be controlled to once every two weeks.

IV. Precautions

The specific time of fertilization also needs to be paid attention to. It is not suitable to fertilize when the temperature is very high and the sunlight is very strong. It is best to do it in the morning or evening.
