The answer to 'sod brown patches' is that there are several common causes, including drought stress, disease, pests, and improper mowing or watering. Symptoms include discolored, thinning, or dead patches in the lawn. Solutions can range from adjusting watering and mowing practices to treating fungal diseases or pest infestations.
For smaller, isolated brown patches, homeowners may be able to reseed or resod the affected areas. However, for more widespread or persistent issues, it's best to consult a professional landscaper who can diagnose the underlying cause and recommend the appropriate treatment.
