With the arrival of the summer rainy season, property owners and professional landscapers across unincorporated Lee County—including Captiva Island—are reminded that the annual summer fertilizer blackout period is officially active. Running from June 1 through September 30, the strict seasonal restriction aims to protect Southwest Florida’s delicate aquatic ecosystems during the months of heaviest rainfall.
At the LeAneSuarezGroup, we know that clean water is the absolute lifeblood of our local real estate market, tourism economy, and island lifestyle. Simple, mindful adjustments to your property maintenance routine this summer play a critical role in preserving the pristine bays, estuaries, and shorelines that make our barrier islands paradise.
“The summer months is when we get most of our rain… Personal actions really go a long way because we’re all in this together.” — Lisa Kreiger, Lee County Natural Resources Department Operations Manager
The Science Behind the Summer Fertilizer Restrictions
First enacted by Lee County in 2008, the environmental ordinance targets a major contributor to water quality degradation: stormwater runoff.
When torrential summer downpours hit over-fertilized lawns, the excess nutrients meant to feed grass are washed directly into local drainage systems, ditches, and eventually, open waterways. These surplus loads of nitrogen and phosphorus act as fuel for Harmful Algal Blooms (HABs), such as red tide and blue-green algae, which deplete oxygen levels in the watershed and threaten local fish and marine wildlife.
Strict Ordinance Mandates & Regulations
To keep local watersheds healthy, property owners must adhere to the following county mandates throughout the summer season:
-
The Nutrient Blackout: Homeowners and commercial lawn services are completely prohibited from applying any fertilizer containing nitrogen or phosphorus to turf or landscapes between June 1 and September 30.
-
Water Body Buffers: No fertilizer of any kind may be applied within 10 feet of any water body, seawall, or wetland boundary.
-
Keep Impervious Surfaces Clear: Fertilizer application is strictly banned on impervious surfaces, including neighborhood roads, residential driveways, and sidewalks.
-
Mandatory Deflector Shields: All mechanical spreaders must be equipped with functional deflector shields to precisely control application directions and prevent granules from drifting into protected water buffers or onto pavement.
-
Manage Yard Waste Responsibly: Grass clippings, leaves, and vegetative trimmings must never be swept, blown, or washed into storm drains, ditches, canals, or onto roads.
YEAR-ROUND FERTILIZER BEST PRACTICES
[ CHECK THE FORECAST ] ──► Never fertilize lawns if rain or heavy storms are predicted.
[ DRY CLEAN ONLY ] ──► Sweep up spilled granules immediately; never hose them away.
[ BUFFER ZONES ] ──► Build a 6-foot native planting zone to naturally filter runoff.
[ PET WASTE ] ──► Always pick up after pets to keep extra nutrients out of storm drains.
Alternative Tips for a Lush, Green Summer Lawn
Skipping chemical applications doesn’t mean sacrificing your property’s curb appeal. County officials recommend several eco-friendly alternatives to keep your landscape thriving naturally:
Practice Smart Mowing
Instead of bagging and discarding grass clippings after you mow, let them remain on the lawn to break down naturally. As they decompose, they cycle clean, organic nutrients right back into the soil. Additionally, ensuring your mower blades are set to the correct, healthy height for your specific grass type keeps turf strong and naturally vibrant during the rainy season.
Embrace Native and Florida-Friendly Plantings
Homeowners can drastically minimize or completely eliminate their dependence on yard chemicals by trading needy turf grass for native Florida vegetation. Native flora and certified “Florida-Friendly” plants are naturally adapted to thrive in local soil profiles. They require minimal supplemental watering and can maintain beautiful, lush growth without heavy chemical interventions.
Join the Campaign
To keep community awareness high, the county is continuing its signature educational push, the “Stop Fertilizing Gnome Matter What” campaign, featuring the local mascot Lee the Gnome across regional billboards, television spots, and social feeds.
