The answer to 'landscaping yellowing' is that there are several common causes for yellowing plants and grass in landscaping, including nutrient deficiencies, disease, pests, and environmental stressors. Symptoms can include discoloration, wilting, and stunted growth. Solutions may involve adjusting soil pH, applying fertilizers, treating pests or diseases, or providing better growing conditions.
For minor issues, homeowners may be able to address the problem through DIY methods like testing soil, applying targeted treatments, or improving irrigation and sunlight exposure. However, more serious or persistent yellowing may require the expertise of a professional landscaper to properly diagnose and resolve the underlying cause.
