Skip the Fertilizer Now Through Sept. 30

Published on May 29, 2026

CLEARWATER, Fla. – Beginning June 1 through Sept. 30, Pinellas County's seasonal fertilizer restrictions are in effect. During the rainy season, it is prohibited to apply lawn or landscape fertilizers containing nitrogen and/or phosphorus. These restrictions help protect local waterways from nutrient pollution caused by stormwater runoff.

In addition, phosphorus fertilizers may not be used at any time of the year unless a soil test confirms they are needed. Fertilizer should also never be applied within 10 feet of a seawall, wetland, pond, lake, creek or other water body.

When fertilizers are applied incorrectly, nutrients can wash into storm drains and eventually reach local creeks, lakes, Tampa Bay and the Gulf. Excess nitrogen and phosphorus contribute to harmful algae blooms, which lower oxygen levels in the water and can lead to fish kills. Removing these pollutants from waterways costs taxpayers millions of dollars each year.

To maintain a healthy lawn during the summer months while protecting the environment, consider these Florida-friendly landscaping practices:

• Look for products labeled "0-0" as the first two numbers on the fertilizer label.

• Apply iron products to help keep grass green without increasing growth.

• Use compost to improve soil health naturally.

• Mow St. Augustine and Bahia grass at a height of 3.5 to 4 inches to encourage deeper, healthier roots.

• Water efficiently and follow local watering restrictions.

• Ensure irrigation rain sensors are functioning properly and turn off irrigation when rainfall is sufficient.

• Choose Florida-friendly plants that are adapted to local conditions and require less water and maintenance.

• Be mindful that reclaimed water contains nutrients and should be used responsibly, especially near water bodies.

When fertilizer applications resume Oct. 1, remember to:

• Select slow-release fertilizer products.

• Apply fertilizer only when needed.

• Follow all package instructions carefully.

• Avoid fertilizing when rain or storms are forecast.

• Apply no more than one pound of nitrogen per 1,000 square feet of lawn.

By following these simple practices, residents can help protect Clearwater's waterways, wildlife and natural beauty for generations to come.
