Lawn Disease Prevention Tips for a Healthier Lawn All Year | TLC

A healthy, lush lawn doesn’t just happen—especially in climates where moisture, humidity, and seasonal changes can wreak havoc on your grass. One of the biggest threats to a beautiful yard? Lawn disease. From brown patch to powdery mildew, common turf diseases can quickly damage even well-maintained lawns if you’re not proactive.

Here are TLC’s top tips for year-round lawn disease prevention that’ll help you stay ahead of issues before they start.

Know the Signs of Common Lawn Diseases

Prevention starts with awareness. Catching turf disease early means you can treat small areas before they spread and compromise your lawn’s health.

Here are a few signs to look out for:

• Circular brown patches
• Gray, powdery residue (mildew)
• Wilting or thinning grass in shaded areas
• Orange rust-colored dust on grass blades
  
  

Different grass diseases thrive in different conditions. Brown patch and dollar spot often appear during warm, wet months, while snow mold shows up after long winters.  

If you're unsure what you're seeing, contact TLC and they can help identify the issues with the lawn. 

5 Steps to Prevent Lawn Disease Year-Round

The best way to deal with disease is to stop it before it starts. These simple but effective lawn care tips will help you build stronger, more resilient turf:

1. Mow with care
   Never cut more than one-third of your grass blade at a time. A stressed lawn is more vulnerable to fungus and disease. Keep mower blades sharp for a clean cut.
2. Water wisely
   Water deeply but infrequently—about 1 inch per week. Shallow, frequent watering promotes disease. Mornings are best to avoid lingering moisture that encourages fungal growth.  Best to avoid watering at night as much as possible.  If you are not sure how much to water, use an empty tuna can which is 1 inch deep, when full you have watered enough.
3. Use disease-resistant grass types
   Choose turf varieties that are well-suited to your region and less prone to disease. TLC can advise you on the best grass types for your lawn.
4. Fertilize at the right time
   Over-fertilizing can promote rapid, weak growth that's more susceptible to disease. Use a balanced fertilizer appropriate for the season. Spring and fall are ideal times to strengthen your lawn.
5. Apply fungicide if needed
   If you’ve had recurring problems, a preventative fungicide application in early spring or late summer can help. Choose a treatment based on the specific fungus or disease threat. Most fungi can be grown out and mowed off, try to use fungicide as a last resort.
