The answer to 'grass yellowing' is that there are several common causes, including nutrient deficiencies, disease, pests, or environmental stress. Symptoms may include patches of yellow or discolored grass, thinning or bare spots, and an overall unhealthy appearance. The good news is that many grass yellowing issues can be resolved through proper lawn care and maintenance.
If the yellowing is widespread or persists, it's best to have a professional lawn care technician diagnose and treat the problem. They can identify the underlying cause and recommend the appropriate solutions, whether that's adjusting your mowing, watering, or fertilization routine, treating for pests or disease, or addressing soil imbalances.
