1、 Fertilization time

The fertilization time of happy tree is usually in spring and autumn. In these two seasons, the climate is relatively mild, the plant growth rate is relatively fast, and the demand for fertilizer is also strong. In summer and winter, the plant will enter a dormant state. If fertilized, the fertilizer will often accumulate and damage the roots in the long run, so it is usually not fertilized in summer and winter

2、 Fertilizer selection

Happy tree has a high demand for nitrogen and potassium. If you don't want it to bloom, you can apply less phosphorus fertilizer and more nitrogen fertilizer. Rotten and compound fertilizers are usually applied during planting. During the growth period of the plant, it is necessary to supplement quick acting liquid fertilizer, such as cake fertilizer and water. In addition, urea and potassium dihydrogen phosphate can also be applied to promote the stout stem of the plant

3、 Fertilization method

Different fertilizers are used differently. The base fertilizer is usually buried at the bottom of the pot when planting or potting, so as to continuously provide nutrients for the plant. Some granular fertilizer can be directly buried in the soil, but it is usually far away from the root to avoid damage to it. Liquid fertilizer can be directly irrigated to the root, but if it is foliar fertilizer, it needs to be sprayed on the leaves

4、 Precautions

Pay attention to the amount of fertilizer applied to the happy tree. If you apply too much fertilizer or the fertilizer is not fully diluted, it is easy to cause fertilizer damage and burn the roots of the plant. At this time, it is necessary to take out the plants from the flower pot in time, cut off the rotten roots with scissors, and spray carbendazim to prevent wound infection. When it is dry, it can be replanted
