Summer Fertilizer Ban Lifts October 1

You can start applying fertilizers with nitrogen (N) and phosphorus (P) again starting October 1st. Remember that to apply P you must have a soil or tissue test documenting a deficiency of this nutrient.

Use a tissue test to document a P deficiency. Soil tests done on alkaline soils nearly always show plenty of P even though it may not be available to the plant because it is tied up in the soil. Tissue testing form.

Remember NOT to apply N or P if the National Weather Service has issued a severe thunderstorm warning or watch, flood warning or watch, tropical storm warning or watch, hurricane warning or watch, or if rain greater than or equal to 2 inches in a 24 hour period is forcast for any portion of Pinellas County.

No N applied to newly established turf or new landscape plants for the first 30 days.

No fertilizer on any impervious surfaces, and spreader deflector shields are required on any broadcast or rotary fertilizer spreaders.

Fertilizer cannot be applied within 10 feet from the top of the bank of any surface water, landward edge of top of a seawall, designated wetland or wetland as defined by the FDEP.

For all questions about the fertilizer ordinance please call the Pinellas County Watershed Division at 464-4425 option 6, email:, or visit their website
