What It Is, Why It Matters, and How to Stay Compliant
Did you know there’s a Florida law that limits fertilizer use during the summer? If you live in the Sunshine State or work in lawn care or pest control, you need to be aware of the seasonal fertilizer ban on those containing nitrogen and phosphorus, in effect from June 1 through September 30.
It’s not just about grass—it’s about clean water, healthy wildlife, and preventing environmental disasters like algae blooms.
What the Ordinance Says
From June 1 to September 30, homeowners, pest control professionals, landscapers, and lawn care professionals cannot apply fertilizers that contain nitrogen or phosphorus to turfgrass or landscapes.
These rules are part of local and state efforts to reduce pollution during Florida’s rainy season, when fertilizers are more likely to wash into storm drains, canals, and eventually into rivers, bays, and the Gulf.
Why This Matters: Stopping Algae at the Source
When nitrogen and phosphorus enter our waterways, they fuel the growth of harmful algae blooms. These blooms:
Smother aquatic ecosystems
Kill fish and marine life by depleting oxygen
Release toxins that can harm people, pets, and wildlife
Damage local economies that depend on clean water and healthy coasts
By avoiding certain fertilizers during the rainy season, we’re all doing our part to protect Florida’s water resources.
Homeowners: What You Should Do
Even if you’re just maintaining your own yard, this ban applies to you. Here’s how to stay in the clear:
Check your labels. Don’t use any fertilizer with nitrogen or phosphorus between June 1 and September 30. Look for alternatives that are labeled “summer-safe” or only contain potassium.
Water wisely. Over-watering can cause runoff—even if you’re not using restricted fertilizers.
Use compost or organic mulch. These can improve soil quality naturally without contributing to runoff pollution.
Don’t fertilize before a storm. If rain is in the forecast, skip the fertilizer completely to avoid washing it straight into nearby waterways.
Pros & Pest Control Companies: What You Need to Know
If you’re a lawn care provider, pest control technician, or landscape professional, following the ordinance isn’t just good practice—it’s required by law.
Use compliant products. Make sure none of your summer blends contain nitrogen or phosphorus.
Train your team. Everyone on staff should understand the ban and how to talk to clients about it.
Keep records. Many counties require documentation of what’s applied and when.
Educate your clients. Let them know skipping fertilizer during summer protects their property—and Florida’s environment.
A Greener Future Starts at Home
Florida’s natural beauty is one of its biggest assets, and protecting it starts with small decisions in our own backyards. By following the fertilizer ban, we can help prevent algae blooms, safeguard marine life, and preserve our waterways for fishing, swimming, boating, and drinking.
Whether you’re a homeowner trying to keep your lawn green or a business owner servicing multiple properties, you have a role to play.
Let’s work together to keep Florida beautiful—from the ground up.
