Rhododendron is a kind of plant that likes fertilizer, so its maintenance requires higher 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.
The base fertilizer used can be some solid fertilizer, such as animal manure.In addition to the usual liquid fertilizer, some foliar fertilizer can also be used appropriately.
1. The application of base fertilizer is relatively simple. After the soil for planting is prepared, it can be directly mixed, and it needs to be evenly mixed.For liquid fertilizer and foliar fertilizer, their application is relatively troublesome, need to be diluted before use, the concentration can not be too high.
2. In addition, the frequency of fertilization can be judged according to the volume of the plant.If it is in the seedling stage, then the requirement for fertilizer is not too high, you can fertilize once a month or so.If the plant is adult and large, the frequency can be controlled at about once every two weeks.
The specific time of fertilization also needs to be paid attention to, when the temperature is very high and the sunshine is very strong, it is not suitable for fertilization, it is best to choose in the morning or evening.
