Fertilizing rhododendrons can be divided into two categories: base fertilizer and top dressing. Base fertilizer is used during planting, and top dressing is used during the growth period. Some solid fertilizers can be used as base fertilizer, and liquid fertilizers and foliar fertilizers can be used as top dressing. Base fertilizer is mixed directly into the soil, and both liquid fertilizer and foliar fertilizer are best diluted before use; the frequency of fertilization can be determined according to the volume of the rhododendron, and the frequency of fertilization for seedlings can be less. It should be noted that the best time to fertilize is in the morning or afternoon. Fertilization at noon is not suitable.

1. Fertilization time

Rhododendron is a plant that prefers fertilizer, so its maintenance requires relatively high fertilization. Fertilizing it 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. Fertilizer types

Use Some solid fertilizers can be used as base fertilizer, such as animal manure. In addition to the usual liquid fertilizer, some foliar fertilizers can also be used for top dressing.

3. Fertilization method

1 The application of basal fertilizer is relatively simple. After preparing the planting soil, it can be mixed directly. It needs to be mixed evenly. For liquid fertilizers and foliar fertilizers, their application is relatively troublesome. They need to be diluted before use, and the concentration cannot 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, its requirements for fertilizer are not too high and can be fertilized once a month or so. If the plant is mature and relatively large, the frequency can be controlled at about once every two weeks.

IV. Precautions

You also need to pay attention to the specific time of fertilization. Fertilization is not suitable when the temperature is very high and the sun is very strong. It is best to do it in the morning or evening. .
