Florida Lawn Problems Guide
Identify, diagnose, and treat 33 common lawn issues affecting Florida homeowners. From fungal diseases to stubborn weeds, find expert solutions for your grass type.
Lawn Diseases
Fungal and bacterial infections that cause brown patches, spots, and lawn decline in Florida's humid climate.
Brown Patch
Brown Patch is Florida's most common lawn fungus, creating circular patches of dead grass during warm, humid conditions. Learn how to identify and eliminate this destructive disease.
Gray Leaf Spot
Gray Leaf Spot is the most damaging disease for St. Augustine grass in Florida, causing rapid decline during hot, humid summer months. Early detection is crucial for saving your lawn.
Dollar Spot
Dollar Spot creates distinctive silver-dollar sized dead patches in Florida lawns, particularly Bermuda and Zoysia grass. This fungal disease thrives when lawns are nitrogen-deficient and drought-stressed.
Take-All Root Rot
Take-All Root Rot is one of Florida's most challenging lawn diseases, silently destroying St. Augustine grass roots before visible symptoms appear. Early detection and proper treatment are essential.
Fairy Ring
Fairy Ring creates mysterious circular patterns in Florida lawns - from rings of dark green grass to dead zones with mushrooms. Understanding the type you have is key to effective treatment.
Pythium Disease
Pythium is a water mold that can devastate Florida lawns seemingly overnight during hot, humid conditions. The greasy, water-soaked patches spread rapidly and require immediate treatment.
Anthracnose
Anthracnose affects stressed Florida lawns during summer heat, causing yellowing and thinning. This fungal disease targets weakened grass and can be controlled with proper treatment.
Helminthosporium Leaf Spot
Helminthosporium leaf spot begins as small spots but can progress to devastating 'melting out' of entire turf areas. Understanding both disease phases is critical for Florida lawn care.
Rust Disease
Rust disease creates a distinctive orange or reddish-brown powder on grass blades that rubs off on shoes and mowers. While alarming in appearance, Rust is one of the easier lawn diseases to control.
Slime Mold
Slime Mold appears as strange crusty masses on grass blades after rainy weather. While alarming in appearance, these organisms are harmless to your lawn and easy to manage.
Pest Damage
Insects and grubs that feed on grass roots, stems, and blades, causing visible damage patterns.
Chinch Bug Damage
Chinch Bugs are the #1 pest threat to St. Augustine grass in Florida, causing yellow patches that rapidly turn brown and die. Fast identification and treatment are essential to save your lawn.
White Grub Damage
White Grubs feed on grass roots underground, causing sections of lawn to die and roll up like carpet. These beetle larvae are a hidden threat that requires proactive treatment in Florida.
Billbug Damage
Billbugs are weevils whose larvae bore into grass stems, causing irregular brown patches in Florida Zoysia and Bermuda lawns. This often-misdiagnosed pest requires targeted treatment.
Mole Cricket Damage
Mole Crickets tunnel through Florida lawns, destroying grass roots and leaving spongy, dying turf in their wake. These destructive pests require strategic timing for effective control.
Spittlebug Damage
Spittlebugs create distinctive frothy masses in Florida lawns while their feeding causes purple-striped damage. This common pest is easily controlled once properly identified.
Caterpillar Damage
Armyworms, sod webworms, and other caterpillars can devastate Florida lawns seemingly overnight, chewing grass blades down to the crown. Quick identification and treatment are essential.
Common Weeds
Invasive plants that compete with your lawn grass for water, nutrients, and sunlight.
Crabgrass
Crabgrass is a persistent warm-season weed that spreads aggressively through Florida lawns. Understanding its life cycle is key to effective control and prevention.
Dandelion
Dandelions are recognizable broadleaf weeds with bright yellow flowers and fluffy seed heads. While less common in Florida than northern states, they still invade lawns during cooler months.
Clover
Clover invades Florida lawns, especially those with low nitrogen fertility. While some homeowners embrace clover's benefits, others want a pure grass lawn.
Dollarweed
Dollarweed thrives in Florida's wet conditions, spreading aggressively through over-watered lawns. Understanding its moisture dependency is key to long-term control.
Doveweed
Doveweed is a warm-season weed that spreads through Florida lawns during summer, forming dense mats in moist areas. Early identification and treatment are essential.
Torpedo Grass
Torpedo Grass is one of Florida's most invasive and difficult-to-control lawn weeds. Its aggressive rhizome system makes eradication extremely challenging.
Sedge (Nutsedge)
Nutsedge looks like grass but grows faster and taller, creating an uneven lawn appearance. This persistent weed reproduces through underground tubers that make it difficult to control.
Spurge
Spurge is a low-growing summer weed that forms dense mats in thin, stressed Florida lawns. Its milky sap and rapid spreading make it a persistent nuisance.
Environmental Stress
Non-living factors like drought, overwatering, and nutrient deficiencies that affect lawn health.
Drought Stress
Drought stress is common in Florida lawns during dry periods, causing wilting, discoloration, and potential death. Early recognition and proper watering can save your lawn.
Overwatering
Overwatering is just as damaging as drought in Florida lawns, causing shallow roots, yellow grass, fungal diseases, and weed invasions. Finding the right balance is essential.
Iron Chlorosis
Iron chlorosis causes yellow grass with green veins, common in Florida's alkaline soils. This nutrient deficiency is easily corrected with iron supplements for quick green-up.
Herbicide Damage
Herbicide damage can devastate Florida lawns when the wrong product is used, rates are exceeded, or drift occurs. Understanding symptoms helps distinguish it from other problems.
Nematode Damage
Plant-parasitic nematodes are microscopic worms that attack grass roots, causing chronic decline in Florida lawns. No cure exists, but management strategies can help.
Healthy Grass Types
Learn what healthy Florida grass looks like so you can identify when something is wrong.
Healthy St. Augustine Grass
St. Augustine is Florida's most popular lawn grass. Knowing what a healthy lawn looks like helps you spot problems early and maintain your turf properly.
Healthy Bermuda Grass
Bermuda grass is prized for its durability and drought tolerance in Florida. Knowing what a healthy Bermuda lawn looks like helps you maintain it properly.
Healthy Zoysia Grass
Zoysia grass offers a premium, low-maintenance lawn option for Florida. Understanding healthy Zoysia helps you maintain its dense, carpet-like appearance.
