1、 Fertilization time

First, when planting gardenia, using some fertilizer is conducive to its growth. In addition, fertilization is needed at the growth stage, and additional fertilization is needed at the flowering stage

2、 Fertilizer type

The base fertilizer used in planting is generally some solid fertilizer, and some slow-release fertilizer can also be used. Organic liquid fertilizer can be used for topdressing in growth period, which can be purchased directly in flower shops. In addition, the additional fertilizer used during flowering is mainly phosphate fertilizer, such as potassium dihydrogen phosphate

3、 Fertilization method

1. Organic liquid fertilizer and potassium dihydrogen phosphate must be added with water, diluted and reused. Concentrated fertilizer cannot be used. When the base fertilizer is used, it needs to be mixed with the soil and then stirred evenly; If it is slow-release fertilizer, you can buy it directly in the soil

2. Fertilization during growth period can be applied once a month. Potassium dihydrogen phosphate used before flowering needs to be used once a week until flowering. It can be used once after flowering, which is conducive to later growth

4、 Precautions

1. It is best to loosen the soil one day before fertilization, so that it can be better absorbed after fertilization the next day

2. Specifically, it is suitable for fertilization in the morning or evening, but not at noon
