Williamson County — Disease Control
Professional lawn disease & fungus control for Brentwood homeowners, delivered by Middle Tennessee's only UT Certified lawn treatment specialists.
Brentwood homeowners take pride in a pristine appearance, but your mature landscapes and extensive tree canopy create the perfect environment for hidden fungal threats. If you have been struggling with brown patches appearing by mid-summer, you are likely dealing with disease rather than drought, and watering more will only accelerate the damage to your lawn.
In established Brentwood neighborhoods like Governors Club, Taramere, or along the I-65 corridor near the Maryland Farms area, it is not a question of if your lawn will face fungal pressure, but when. Because so many of you rely on legacy irrigation systems and enjoy the cooling shade of large trees, your grass often remains soaked with dew well into the morning hours. When nighttime temperatures climb above seventy-five degrees, you have a perfect breeding ground for disease. Most homeowners I speak with do not realize their lawn is sick until they see large, circular dead spots in July or August. They assume the lawn is just thirsty, so they turn up the water. This is exactly the wrong move. Excess moisture increases spore production and causes infection to spread downhill, turning a localized problem into a total lawn failure. By the time the summer heat peaks, your grass is often fighting a losing battle against mechanical stress, soil heat, and foot traffic. Fungal disease is the final factor that causes these lawns to collapse completely. Many services in Brentwood offer low-tier plans that exclude fungicides. When your grass inevitably turns brown, they will leave a note on your door claiming you have brown patch and asking for double the price of a standard visit to treat it. I consider this approach unethical. The label is the law, and treating preventively is the only way to effectively control disease. This is why I include fungicides in every single one of my plans. I do not believe in tiered systems or surprise bills for rescue treatments. As a UT Certified Horticulturist, I start my preventive program in May, a full month before most companies even think about disease. If you wait until the damage is visible in June or July, you are already playing catch-up. When a plant stops spending its energy fighting off fungus, it becomes dramatically more drought-tolerant and resilient. It can handle the wear and tear of family barbecues and survive the occasional missed watering. My goal is to keep your lawn healthy from the start so that you do not have to watch it wither away every summer.
Middle Tennessee's transition zone climate—characterized by hot, humid summers and heavy overnight dew—creates extreme fungal pressure for cool-season grasses like fescue. Brown patch thrives in these exact conditions. A preventive fungicide program is not a luxury here; it is a necessity for maintaining a thick, healthy fescue lawn through the summer months.

You are likely dealing with fungal disease, which thrives in our high-humidity environment. Watering actually makes the fungus spread faster, so the more you water, the more the disease destroys your lawn.
No, fungicides can be used curatively to stop active outbreaks and save the lawn. However, we must transition to a preventive schedule to prevent resistant strains from developing in your soil.
Preventive treatment is the standard of care directed by the product labels and the only way to stay ahead of the disease. Starting in June or July means you are already reacting to damage that has started to ruin your lawn.
You may have been relying on frequent, expensive reseeding to mask the problem, but that does not address the underlying disease. Removing the fungal stress allows your existing grass to become more drought-tolerant and healthy without needing constant, costly repairs.

I've been using Mr. Lawn (AJ) for over a year. I am new to the state and saw his signs in a few of my neighbors' yards. Their yards looked the best so I called him first. From the first phone call and throughout this…
