If you have yellow patches appearing on your lawn, this may be due to a lack of nitrogen in the soil or an overabundance of nitrogen. To address this issue, you can consider the following options:
Adjust fertilization: Adjust the ratio of fertilization to ensure adequate nitrogen levels in the soil.
Increase watering: Adequately increasing watering helps to improve oxygen levels in the soil, improving the growing environment for the roots.
Appropriate fertilization: Appropriately apply appropriate fertilizer to help restore lawn growth.
Timely weed removal: Remove weeds in yellow areas promptly, which will help the lawn return to normal growth.
If the situation is serious, please consult a professional horticulturist.
