1, reason for dimming: Fu Guizhu exposed to strong light for too long, yellow spots will grow on the leaves, and the whole leaves will look yellow and dull.

Solution: move Fu Guizhu to a place where light is scattered indoors and slowly maintain it.

2. Reasons for brightening: Fu Guizhu has been in the shade for a long time, and there is not enough sunlight for photosynthesis, so the leaves cannot synthesize nutrients and turn yellow.

Solution: move it to a sunny but not strong place for maintenance.

3. Reasons for replanting by cutting roots: Too much watering or fertilization will affect the roots of Fu Guizhu. Light will lead to root blackening, while heavy will lead to root rot. After the root system is damaged, it will directly affect the efficiency of nutrient absorption, leading to insufficient nutrition and yellowing of leaves.

Solution: Take the rich bamboo out of the water or soil, observe the roots, and cut off the black and rotten roots with sterilized scissors. Then spray some medicine on the wound to sterilize it, and then put it in the shade to dry. Wait until the medicine is dry, and then use a new medium for culture.

4. Pour more water. Reason: Water is the raw material of the photosynthesis reaction of Fu Guizhu. Once water is lacking, the leaves will not be able to produce photosynthetic nutrients, and then turn yellow.

Solution: Water Fu Guizhu more to ensure adequate water supply.

5. Reasons for fertilizing: If Fu Guizhu is not fertilized for a long time, the nutrients that the plant can extract will be insufficient, and the leaves will turn yellow without nutrients.

Solution: Apply some fertilizer to Fu Guizhu, but not too much, and apply it thinly and diligently.
