What are the taboos of fertilizing flowers?

Fertilizing taboos for flowers:

1. Do not fertilize newly planted plants. Newly planted plants have many wounds; if stimulated by the outside, they cannot heal and will cause root rot.

2. Do not fertilize during the flowering period. Fertilizing during the flowering period will cause buds and flowers to drop.

3. Do not fertilize during the dormant period. Flowers stop or slow their growth during the dormant period, their metabolism is slow, and photosynthesis is poor. If fertilizer is applied, it will quickly break the dormancy and cause the plant to continue growing, which will consume more nutrients and affect the flowering of the coming year.

4. Do not fertilize directly under the root crown. As flowers and plants grow continuously, their root systems also gradually expand accordingly. If fertilizer is applied under the root crown, it is instead not conducive to full absorption and utilization. Therefore, according to the plant's growth, fertilizer should be applied in holes at an appropriate distance from the roots or at the edge of the pot, so as to facilitate root absorption.

5. Do not apply concentrated fertilizer. When fertilizing potted flowers, the concentration must not be too high or the amount too much, otherwise it will cause them to wither and die. Generally, the principle of "apply thin fertilizer frequently" should be followed, and three parts fertilizer to seven parts water is the most appropriate.

6. Do not apply raw fertilizer. If undecomposed fertilizer is applied, it will not only easily breed insects and maggots, often give off a foul odor and pollute the environment, but also ferment when it encounters water and damage the plant's root system.

7. Do not apply nitrogen fertilizer alone. When fertilizing flowers, nitrogen, phosphorus, and potassium should be used together. If nitrogen fertilizer is applied alone, it is easy to cause the branches and leaves to prolong their growth period, delay flowering or prevent flowering, or produce small and pale flowers.

8. Do not fertilize diseased and weak plants. The branches of diseased and weak plants are thin and weak, photosynthesis is poor, and metabolism is slow. They "cannot be tonified when weak." If fertilizer is applied casually, it is easy to cause fertilizer damage.
