1、 The newly planted plants will not be fertilized

Newly planted plants have many wounds. If stimulated by the outside world, they will not heal and cause rotten roots.

2、 No fertilizer at flowering stage

Fertilization during flowering will cause bud, flower and fruit falling.

3、 No application during dormancy

Flowers stop or slow down their growth during the dormancy period, with slow metabolism and poor photosynthesis. If fertilizer is applied, the dormancy will soon be broken and the plant will continue to grow. In this way, more nutrients will be consumed and the flowering of the next year will be affected.

4、 Not under the root stump

With the continuous growth of flowers and plants, its root system also expands gradually. If fertilization is applied under the root stump, it is not conducive to full absorption and utilization. Therefore, depending on the growth of the plant, acupoint application should be applied at the appropriate place away from the root or the edge of the basin to facilitate the absorption of the root.

5、 Concentrated fertilizer cannot be applied

When fertilizing potted flowers, the concentration should not be too large or the dosage should not be too much, otherwise it will die. Generally, the principle of "thin fertilizer and frequent application" should be mastered, and the most appropriate one is three parts of fertilizer and seven parts of water.

6、 No raw fertilizer can be applied

If you apply non rotten fertilizer, it is not only easy to produce insects and maggots, but also often emit odor and pollute the environment. In addition, it will ferment in the presence of water and damage the root system of the plant.

7、 Not only nitrogen fertilizer

When fertilizing flowers, nitrogen, phosphorus and potassium should be used together. It is best to use cake fertilizer, stables fertilizer, compost, chicken, duck and pigeon manure, bone meal, leaves, plant ash and other farm manure. If nitrogen fertilizer is applied only, it is easy to prolong the growth period of branches and leaves, delay flowering or no flowering, or the flowers are small and light in color.

8、 No application for sick and weak plants

The branches of sick and weak plants are thin, the photosynthesis is poor, the metabolism is slow, "deficiency is not supplemented". If you apply fertilizer casually, it is easy to cause fertilizer damage.
