CLEARWATER, Fla. – Now through Sept. 30, skip the fertilizer. It is illegal in Pinellas County to fertilize lawns during the rainy season, and it’s also the reason slow-release products are required the rest of the year.

Fertilizers containing nitrogen and/or phosphorus cannot be applied to lawns or landscape plants, according to Pinellas County ordinance. Incorrect use of fertilizer can allow nutrients to leach into the groundwater and wash into storm drains that flow to creeks, lakes, Tampa Bay and the Gulf of Mexico. Excess nutrients can cause harmful algae blooms, which lower oxygen levels and lead to fish kills. The treatment to remove these nutrients costs taxpayers millions of dollars each year.

During the rest of the year, use fertilizers properly. Here’s how:

  • Make fertilizer selections based on need. Decide which nutrients will give you the result that you want for your lawn.
  • Use fertilizers sparingly to reduce nitrate levels. Less is better. Read and follow all instructions on the package.
  • Do not fertilize when storm events are forecast. This will help reduce the level of nutrients washing into water systems during and after the storm.
  • Select slow-release fertilizers. They are kinder to the environment and usually cost less. Look for terms such as “time-release,” “slow-release” or “water insoluble nitrogen” on the fertilizer’s package.
  • Remember to fertilize only when needed. Do not apply more than one pound of nitrogen per 1,000 square feet of grass.

Do your part to preserve Clearwater’s water, coastlines and wildlife – the very things that help make this city bright and beautiful.
