What’s Infecting Your Lawn? Common Causes and How to Stop Them
If infections occur, a healthy lawn can quickly become a patchy, discolored mess. What causes these issues, and how can you prevent them?
Fungal Diseases
Fungi are one of the top causes of lawn infections. They thrive in warm, humid conditions and can spread fast.
Brown Patch: Circular brown spots, especially in hot, wet weather
Dollar Spot: Small, straw-colored patches that can merge into larger areas
Fairy Rings: Circular patterns of dark green or dead grass, sometimes with mushrooms
TIP: Avoid overwatering, mow at the right height, and don’t over-fertilize with nitrogen.

Pests That Damage Roots
Insects like grubs and sod webworms can weaken your lawn, making it more vulnerable to disease.
Grubs: Feed on grass roots, causing dead patches that peel up like carpet
Sod Webworms: Larvae that chew grass blades, leaving behind brown patches
TIP: Watch for signs like birds digging or moths flying low at dusk. Early treatment is key.
Poor Lawn Practices
Overwatering or watering at night
Mowing too short
Compacted soil that prevents drainage
Excess thatch buildup
TIP: Aerate your lawn, water early in the morning, and mow at the recommended height for your grass type.
Weather Conditions
Extreme weather, especially prolonged humidity or sudden temperature shifts, can create the perfect storm for spreading infections.
Lawn infections can be frustrating, but they're manageable with the proper knowledge and care. Keep an eye out for early signs, adjust your lawn care habits, and don’t hesitate to call us if things get out of hands.
