Causes
Brown Patch is fueled by a combination of factors, and understanding these causes is essential for effective prevention and management. The primary contributors in Houston’s climate include:
- Humidity: Houston's high humidity levels provide an ideal environment for the development of Brown Patch. The fungus thrives in moist conditions, making lawns susceptible after periods of rain or heavy watering.
- Temperature Fluctuations: Warm temperatures during the day and cooler nights, typical of Houston's climate, create an environment conducive to Brown Patch development.
- Overwatering: Excessive watering can lead to waterlogged soil, creating a breeding ground for the fungus. In Houston, where irrigation is often necessary, proper watering practices are crucial.
Symptoms
Identifying Brown Patch is crucial for timely intervention. Common symptoms include:
- Circular Patches: Brown Patch typically manifests as circular or irregularly shaped brown patches in the lawn.
- Distinctive Borders: The affected areas often have a dark border, giving the patches a "smoke ring" appearance.
- Wilting and Discoloration: Grass within the patches will exhibit wilting and a change in color from green to brown.
