1. Adjust the amount of wateringIf the yellowing is caused by too much water, the young leaves will turn yellow, and the water should be controlled immediately. If the yellowing is caused by drought or lack of water, the entire plant will turn yellow, and in severe cases it may even die. Water should be added in time. 2. Reasonable fertilizationIf the yellowing is caused by too much fertilizer or too concentrated fertilizer, it will cause the young leaves to thicken. You should limit the amount of fertilizer in time, carry out inter-cultivation, and control the amount of water. If the yellowing is caused by insufficient fertilizer, too low fertilizer concentration or too long interval between two fertilizations, the young leaves will turn yellow first. Fertilizer should be added in a timely and reasonable manner. However, when adding fertilizer, remember not to add too much fertilizer at one time to avoid burning the roots. 3. Sterilize and spray pesticides in timePests and diseases can also cause the leaves of the plant to turn yellow. When possible infection is discovered, the plant should be inspected in time. When infected plants are found, decisive measures should be taken to wash the diseased plants and use fungicides. If no infected plants are found, the yellowing of leaves may be caused by infection in the roots. You can use appropriate sterilizers for irrigation to eliminate diseases and pests in the root system. |
