What to do if daffodil leaves turn yellow

1. Supplement nitrogen

(1) Specific reasons: The growth period requires more nutrients. If too little fertilizer is applied for a long time, or the plant has not been repotted for a long time, there will be a serious lack of nutrients and the leaves will easily turn yellow. This mainly refers to the element nitrogen.

(2) Solution: Add some nitrogen-containing fertilizers in time. But don't use too much at one time, and the amount should not be too large.

2. Adjust the room temperature

(1) Specific reasons: It often occurs in winter. If the temperature is too low, the plants will suffer from frost damage, which can easily cause the leaves to turn yellow, and in severe cases, they will wither and die.

(2) Solution: Adjust the room temperature immediately after discovery, or move to a warmer place.

3. Supplement iron

(1) Specific reason: If the water used for watering lacks iron, the leaves will turn yellow.

(2) Solution: Supplement some soluble iron elements, add some alum fertilizer water, etc.

4. Supplemental lighting

(1) Specific reasons: The plant has a greater demand for light, especially in winter. If the plant is shaded for a long time and does not receive enough light, its branches and leaves will turn yellow.

(2) Solution: Add light immediately after yellowing leaves are found. It is necessary to ensure more than six hours of light per day. However, if you encounter light that is too strong, you must block it.

5. Regular pruning

(1) Specific reasons: The tree has not been pruned for a long time, there are too many messy branches and leaves, poor light transmission, and insufficient nutrient supply, which can easily cause the leaves to turn yellow.

(2) Solution: If you find that the branches and leaves are too lush, prune them in time. It is best to prune them regularly. In addition, some fertilizer can be added appropriately.
