The humid, sweltering summers of East Tennessee provide the perfect backdrop for backyard barbecues, but for your turf, these conditions can be a recipe for disaster. Homeowners in Kingsport, Johnson City, and Bristol often wake up to find unsightly, circular patches of tan grass marring their otherwise vibrant yards. This isn't just a sign of a thirsty lawn; it is likely the result of Brown Patch, a persistent fungal disease that thrives in our specific regional climate. Achieving a resilient landscape requires a proactive lawn care approach that balances hydration with soil health.
At Promier Landscapes, we have spent over twenty years helping local properties navigate these seasonal stressors to maintain a manicured, professional look.
Identifying the Signs of Fungal Stress
Brown Patch, caused by the fungus Rhizoctonia solani, typically appears when nighttime temperatures exceed 65°F and daytime humidity remains high. Identifying it early is the best way to prevent widespread damage across your property.
Keep an eye out for these specific symptoms:
Circular Discoloration: Yellowish-brown patches ranging from a few inches to several feet in diameter.
Smoke Rings: Dark, grayish-black borders around the edges of the patch, most visible during damp mornings.
Healthy Centers: Sometimes green grass will persist in the middle of the patch, creating a "doughnut" appearance.
Leaf Lesions: Small, tan spots with dark brown borders on individual grass blades.
Because our local soil often contains heavy clay, drainage issues can trap moisture at the root level, which further encourages these fungal spores to spread rapidly.
Cultural Practices to Combat Brown Patch
Managing this disease involves more than just a quick fix; it requires adjusting your daily maintenance routine to favor the grass over the fungus. By making a few simple changes, you can significantly reduce the risk of infection.
Adjust Your Watering Schedule: Avoid watering in the late evening. Aim for early morning between 6:00 AM and 9:00 AM so the sun can dry the grass blades quickly.
Mow at the Right Height: Set your mower blades higher during the summer. Taller grass shades the soil and reduces stress on the plant’s crown.
Improve Airflow: Thin out overhanging tree limbs to allow more sunlight and wind to reach the turf, which helps moisture evaporate.
Clean Your Equipment: Fungus can hitch a ride on mower blades. Rinse your deck after mowing an infected area to avoid spreading it to healthy sections.
