The answer to 'sod turning brown' is that there are several common causes, including drought, disease, pests, and improper care. Symptoms can include discoloration, wilting, and patchy or uneven growth. Solutions depend on the underlying issue, but may involve adjusting watering, treating disease or pests, and ensuring proper mowing and fertilization.
In many cases, homeowners can address minor sod issues through DIY measures like adjusting watering, aerating, or applying spot treatments. However, for more severe or persistent problems, it's best to consult a professional landscaper who can diagnose the root cause and recommend the appropriate solution.
