1、 Fertilization time

Rhododendron is a kind of plant that likes fertilizer, so its maintenance requires high fertilization. Its fertilization can be divided into two categories. One is base fertilizer, which is used when planting; One is topdressing, which is used when it grows faster

2、 Fertilization type

The base fertilizer used can use some solid fertilizer, such as animal manure. In addition to the liquid fertilizer usually used for topdressing, some foliar fertilizer can also be used appropriately

3、 Fertilization method

1. The application of base fertilizer is relatively simple. After the planting soil is prepared, it can be directly mixed, and it needs to be mixed evenly. For liquid fertilizer and foliar fertilizer, their application is relatively troublesome. They need to be diluted and reused. The concentration cannot be too high

2. The other is the frequency of fertilization, which can be judged according to the volume of the plant. If it is in the seedling stage, the requirement for fertilizer is not too high. It can be applied once a month or so. If the plant is adult and large, the frequency can be controlled once every two weeks

4、 Precautions

We should also pay attention to the specific time of fertilization. It is not suitable for fertilization when the temperature is very high and the sun is very strong. It is best to carry out fertilization in the morning or evening
