If you've noticed discolored patches, strange spots on your grass blades, or thinning turf this year, you're not alone. We've seen more fungal activity in lawns than in the past five years combined. The culprit? Blight / Fungus! This season's unique weather pattern of high heat, persistent rain, and saturated soil has created the perfect storm for fungus to thrive.
Fungus isn't something that suddenly appears in your yard; it's always there, waiting for the right conditions to become active. When the weather is right, you might notice discolored patches, distinct patterns like circles or rings, or grass that appears matted or slimy. This happens because fungal pathogens love:
- Prolonged moisture: Soil that stays wet for too long.
- Heat and humidity: Warm temperatures combined with a lot of moisture in the air.
- Poor airflow: Dense turf or compacted soil that traps moisture.
- Improper mowing: Mowing too short or with dull blades that stress the grass.
Your Two-Part Strategy for a Healthy Lawn
Tackling lawn fungus requires a two-pronged approach. The first part is all about simple, foundational habits you can adopt.
1. Cultural Practices: Your Most Powerful Tool
- Mow High (3-4 inches) with Sharp Blades: Taller grass shades the soil, keeping it cool and promoting strong root systems. A sharp blade makes a clean cut that heals quickly, preventing pathogens from entering the plant.
- Water Deeply and Infrequently in the Morning: Watering early gives grass blades the entire day to dry, minimizing the window for fungal growth. Avoid watering at night, as this is the biggest contributor to disease.
2. Professional Care
The second part of the strategy involves professional services that can correct underlying issues and strengthen your lawn.
Core Aeration
This service creates small channels in your soil to relieve compaction and enhance drainage.
Premium Slow-Release Fertilizer
A balanced, slow-release fertilizer provides steady nutrition, avoiding the rapid, weak growth that can make a lawn more susceptible to disease.
Overseeding
Introducing high-quality, disease-resistant grass seed varieties creates a dense, thick lawn that is your best natural defense.
Our Stance on Fungicides
While chemical fungicides are an option, we generally don't recommend them for residential lawns. They're often a costly, temporary fix that can harm the beneficial microbial ecosystem your soil needs to be healthy. A long-term strategy built on proper care is almost always the superior approach for a truly resilient lawn.
