Identify Your Lawn Problem
Florida lawns face unique challenges. Sandy soils, intense sun, heavy rainfall, and warm-season grasses like St. Augustine, Bahia, and Zoysia all behave differently than lawns in other parts of the country.
Use the guide below to find the issue you’re experiencing and learn how to correct it.
What Does Your Lawn Look Like?
Select the issue that best matches your lawn to jump to the solution.
Yellow or Pale Grass
A pale lawn usually points to nutrient loss, poor soil health, or watering issues.
What’s Happening
If your lawn looks pale, yellow, or washed out instead of a deep green, it’s usually a sign that the grass isn’t getting enough nutrients or that the soil is struggling to hold them.
Possible Causes
• Nitrogen deficiency
• Nutrients washing away from sandy soil
• Overwatering or poor drainage
• Compacted soil restricting root growth
• Seasonal stress
How to Fix It
• Apply a balanced, slow-release fertilizer
• Water deeply but less frequently
• Leave grass clippings on the lawn after mowing to recycle nutrients
• Aerate compacted areas if necessary
Florida Lawn Tip
Florida’s sandy soils are especially prone to nutrient loss from rainfall and irrigation, which is why consistent feeding during the growing season is vital for lawn health.
Where FloridaGreen Can Help
Slow-release fertilizers help provide steady nutrients over time, which can reduce the sudden nutrient swings that often cause yellowing.
Patchy Lawn
A patchy lawn is often caused by uneven growth, weak soil, or stress from traffic, shade, or pests.
What’s Happening
Patchy lawns occur when grass grows unevenly, leaving thin areas scattered throughout the yard.
Possible Causes
• Uneven fertilizer application
• Shade stress
• Soil nutrient imbalance
• Heavy foot traffic
• Pest damage
How to Fix It
• Fertilize consistently during the growing season
• Improve soil health over time
• Reduce traffic in weak areas
• Raise mowing height slightly for St. Augustine grass
• Reseed or plug damaged areas
Florida Lawn Tip
Fertilization that improves soil health can help encourage thicker turf that naturally fills patchy areas.
Where FloridaGreen Can Help
Improving soil health and providing consistent nutrients can help encourage thicker growth, allowing your lawn to naturally fill in patchy areas over time.
Brown Spots
Brown spots typically signal stress from drought, disease, pests, or improper lawn care practices.
What’s Happening
Brown spots can appear suddenly and spread quickly if the underlying cause isn’t addressed.
Possible Causes
• Lawn fungus
• Drought stress
• Dog urine
• Fertilizer burn
• Insect damage
How to Fix It
• Identify whether the issue is drought, disease, or pests
• Water deeply but avoid frequent shallow watering
• Avoid excessive fertilizer application
• Improve airflow and drainage
Florida Lawn Tip
Warm, humid conditions in Florida can make lawns more susceptible to fungal diseases.
Where FloridaGreen Can Help
Slow-release fertilizers reduce the risk of fertilizer burn compared to fast-release synthetic fertilizers.
Thin or Weak Grass
Thin grass usually means your lawn isn’t getting what it needs to grow thick, healthy, and resilient.
What’s Happening
A thin lawn allows weeds to invade and struggles to recover from stress.
Possible Causes
• Poor soil health
• Nutrient deficiencies
• Excess shade
• Incorrect mowing height
How to Fix It
• Fertilize consistently during the growing season
• Aerate compacted soil
• Adjust mowing height to the recommended level
• Improve sunlight exposure if possible
Florida Lawn Tip
Warm-season grasses grow best when regularly fed during the active growing season.
Where FloridaGreen Can Help
Organic-based fertilizers contribute nutrients while helping improve soil structure over time.
Weeds Taking Over
When weeds start to take over, it’s usually a sign your lawn is thin, stressed, or lacking nutrients.
What’s Happening
Weeds thrive when grass is weak or when bare soil is exposed.
Possible Causes
• Thin turf
• Poor mowing practices
• Lack of nutrients
• Disturbed soil
How to Fix It
• Maintain proper mowing height
• Fertilize to strengthen grass growth
• Spot treat weeds if necessary
• Overseed or plug bare areas
Florida Lawn Tip
The best defense against weeds is a dense, healthy lawn.
Where FloridaGreen Can Help
Consistent fertilization encourages thicker grass that naturally crowds out weeds.
Bare Spots
Bare spots form when grass dies off or fails to establish due to damage, poor soil, or heavy use.
What’s Happening
Bare spots occur when grass dies or fails to establish.
Possible Causes
• Pet damage
• Heavy foot traffic
• Soil compaction
• Disease or insects
How to Fix It
• Loosen soil in the affected area
• Add organic matter
• Reseed or plug grass
• Protect the area until grass establishes
Florida Lawn Tip
Bare soil can quickly invite weeds if new grass is not established quickly.
Where FloridaGreen Can Help
Adding nutrients during new growth helps newly planted grass establish faster.
Hard or Sandy Soil
Florida’s sandy or compacted soils can struggle to hold nutrients and water, making it harder for grass to thrive.
What’s Happening
Florida lawns often grow in sandy soils that drain quickly and struggle to retain nutrients.
Possible Causes
• Low organic matter
• Heavy rainfall washing nutrients away
• Soil compaction
How to Fix It
• Add organic matter over time
• Aerate compacted areas
• Apply slow-release fertilizers
Florida Lawn Tip
Improving soil health gradually leads to stronger, deeper root systems.
Where FloridaGreen Can Help
Products containing organic material can help improve soil structure while feeding the lawn.
Grass Not Growing
If your lawn isn’t growing, it’s often due to poor soil conditions, lack of nutrients, or environmental stress.
What’s Happening
If your lawn seems stuck and doesn’t grow despite watering and mowing, the soil may be lacking nutrients.
Possible Causes
• Nutrient deficiency
• Compacted soil
• Excess shade
• Poor irrigation practices
How to Fix It
• Apply fertilizer during the growing season
• Aerate compacted soil
• Adjust irrigation schedule
• Reduce shade where possible
Florida Lawn Tip
Warm-season grasses grow most actively in late spring and summer.
Where FloridaGreen Can Help
When grass isn’t actively growing, it’s often lacking nutrients or struggling in poor soil. A steady, slow-release feeding approach can help support consistent growth during the active season.
Too Much Thatch
Excess thatch can block water and nutrients from reaching the soil, preventing healthy growth.
What’s Happening
Thatch is a layer of dead grass and organic debris between the soil and grass blades.
Possible Causes
• Overfertilization
• Poor microbial activity in soil
• Lack of aeration
How to Fix It
• Dethatch if the layer becomes excessive
• Aerate the lawn
• Improve soil health
Florida Lawn Tip
Healthy soil microbes naturally break down thatch over time.
Where FloridaGreen Can Help
Organic-based fertilizers can support microbial activity in the soil, which helps break down excess thatch naturally over time.
Fungus or Disease
Fungal issues are common in Florida and often show up as discoloration, patches, or thinning grass.
What’s Happening
Florida’s warm and humid climate can create ideal conditions for lawn diseases.
Possible Causes
• Brown patch
• Dollar spot
• Take-all root rot
How to Fix It
• Water early in the morning
• Improve drainage
• Avoid excessive nitrogen spikes
• Reduce humidity around grass blades
Florida Lawn Tip
Water early in the morning so the grass has time to dry throughout the day. Avoid watering at night, as prolonged moisture creates ideal conditions for fungal growth.
Poor Drainage
Poor drainage can lead to waterlogged soil, suffocating roots and weakening your lawn.
What’s Happening
Standing water or soggy soil can suffocate grass roots.
Possible Causes
• Compacted soil
• Heavy clay pockets
• Poor grading
How to Fix It
• Aerate compacted soil
• Improve yard grading
• Install drainage if necessary
Florida Lawn Tip
After heavy Florida rains, watch for areas where water sits longer than a few hours. These spots often need aeration, grading, or drainage solutions to prevent long-term damage.
Insect Damage
Insect damage can quickly destroy healthy grass by feeding on roots or blades.
What’s Happening
Certain insects feed on grass roots or blades and can quickly damage a healthy lawn.
Signs of Insect Damage
• Grass pulling up easily
• Irregular brown patches
• Visible insects in turf
Common Florida Lawn Pests
• Chinch bugs
• Grubs
• Armyworms
• Mole crickets
How to Fix It
• Identify the pest correctly
• Apply targeted treatments if necessary
• Maintain strong turf health
Florida Lawn Tip
Check your lawn regularly during warmer months by pulling lightly on the grass. If it lifts easily or you notice increased bird activity, insects may be present.
Best Lawn Practices for Florida
- Mow Properly – Never remove more than 1/3 of grass blade.
- Water Correctly – Water deeply 1–2 times per week.
- Fertilize Consistently – Florida lawns benefit from slow steady feeding.
- Build Soil Health – Healthy soil grows healthier grass.
Recommended Fertilization Schedule
"If You're Mowing, You Should Be Throwing."
During the active growing season, fertilize every 8–10 weeks to maintain consistent nutrient availability and support healthy turf growth.
