Pinellas County's rainy season fertilizer restrictions will run from Monday, June 1, through Sept. 30.
The County's Fertilizer Ordinance prohibits the sale or application of lawn and landscape fertilizers containing nitrogen and/or phosphorus during that timeframe. Phosphorus cannot be used at any time of the year unless a soil test confirms it is needed. Also, fertilizer can never be applied within 10 feet of the top of a slope leading to a seawall, wetland, or waterbody.
The County regulates landscape maintenance practices all year, both for property owners who take care of their own lawns and for professionals. We can all use best management practices to have healthy lawns and protect our local waterbodies from receiving excess nutrients. Pinellas County offers a quarterly free Landscape Best Management Practices course, registration information here.
The purpose of the restrictions is to prevent fertilizer runoff and yard waste from harming lakes, ponds, rivers, Tampa Bay and the Gulf of America and from leaching into groundwater. Excess nitrogen and phosphorus can cause harmful algae blooms that lower oxygen levels and lead to fish kills.
Pinellas County recommends using summer-safe lawn care products and landscaping best management practices to keep a healthy landscape during the summer:
Pinellas County is one of more than 90 Florida communities that have summertime fertilizer restrictions.
