Lawn Diseases That Can Strike in Florida Winter

Lawn Diseases That Can Strike in Florida Winter
 

Even though Florida winters are milder than in many states, your lawn isn’t completely safe from problems during the cooler months. Winter weather can create conditions that encourage certain lawn diseases, and homeowners often don’t realize a problem is developing until damage is visible. Here’s what you need to know to protect your lawn this season.

Common Winter Lawn Diseases in Florida

1. Brown Patch

   • Brown patch is caused by a fungus that thrives in cool, wet conditions—exactly what Florida winters sometimes provide.

   • Signs: Circular brown patches in your grass, often with yellow halos.

   • Prevention: Avoid overwatering and improve air circulation in dense lawns.

2. Gray Leaf Spot

   • Most common on St. Augustine and Bermuda grass. The fungus shows up when nights are cool and damp.

   • Signs: Small gray or tan spots with dark borders on the grass blades.

   • Prevention: Proper mowing, removing thatch buildup, and treating with fungicides if needed.

3. Pythium Blight

   • Though more common in humid summers, mild winters with occasional rain can trigger outbreaks.

   • Signs: Greasy-looking patches of grass that appear water-soaked and can spread quickly.

   • Prevention: Avoid excessive irrigation and treat promptly if you notice signs.

4. Leaf Rust

   • Caused by fungi that produce orange to reddish powder on grass blades.

   • Signs: Orange or rust-colored spots on grass leaves; may thin out lawns over time.

   • Prevention: Regular mowing and fertilization help strengthen grass defenses.
