Florida Lawns Are Especially Vulnerable to Grey Leaf Spot

If you have St. Augustine grass on your property, you’re likely familiar with gray leaf spot. This damaging turf disease is particularly common in Pinellas County, Florida, where prolonged rainfall and high humidity create the perfect breeding ground for lawn fungus.

In fact, from late spring to early fall, especially during Florida’s rainy season, lawns across the Tampa Bay area are regularly affected. At Eagle Lawn and Pest Control, we know how quickly Grey Leaf Spot can transform healthy grass into dry, patchy, burned-looking turf—and we’re here to stop it before it spreads.

What Is Grey Leaf Spot, and Why Does It Matter?

Grey leaf spot is a fungal lawn disease that infects the blades of turfgrass—especially warm-season varieties like St. Augustine. It doesn’t usually kill an entire lawn, but it causes serious cosmetic damage, weakens turf health, and invites additional disease or insect activity if left untreated.

What Triggers Grey Leaf Spot in Florida Lawns?

  • High humidity and frequent rainstorms
  • Warm temperatures (spring through fall)
  • Overwatering or poor drainage
  • Excess nitrogen or fertilization
  • Lawn stress from mowing too low or poor airflow

How to Recognize Grey Leaf Spot on Your Lawn

Identifying Grey Leaf Spotting early is critical to preventing widespread damage. Here's what to look for:

Common Signs of Grey Leaf Spot

  • Small olive green or brown pinhead-sized spots on grass blades
  • Spots may have gray, tan, or purple centers that grow larger over time.
  • During high humidity, the fungus produces spores in the center of the spots.
  • Lawns may look dry, burned, or mold-covered—even if recently watered.
  • Infected areas often appear thin, brittle, or dead.

The disease often starts small but spreads quickly—especially in humid areas with thick shade or poor airflow. Once it becomes visible across your lawn, it can be difficult to contain.

How Grey Leaf Spot Spreads

This fungus moves fast. It can travel through:

  • Wind and rain splash
  • Irrigation runoff
  • Pets walking across infected zones
  • Even lawn equipment used in multiple areas

If left untreated, gray leaf spot can spread from your lawn to your neighbors’, impacting an entire block.
