Fertilizer Ordinance

Stormwater runoff is a major source of pollution flowing into our natural waterbodies. The Seminole County Fertilizer Ordinance regulates fertilizers containing nitrogen and/or phosphorus and provides specific management guidelines for fertilizer application to minimize negative impacts to our natural waterbodies.

This ordinance is for unincorporated Seminole County, but all seven cities within the County have adopted this ordinance, either in its entirety or in large part.

Key Highlights of the Fertilizer Ordinance

Fertilizer containing nitrogen or phosphorus cannot be applied to turf during the restricted season from June 1 to September 30 each year. Fertilizers containing Iron, Manganese and other "micronutrients" (also referred to as "summer blends") can be applied from June to September to keep lawns healthy and green (as recommended by Florida Yards Neighborhood/Florida Friendly Landscape Program).
Fertilizer containing nitrogen that is used during the non-restricted season, from October 1 to May 31, must contain 65% or more slow release nitrogen.
Fertilizer containing phosphorus cannot be applied to turf or plants unless a state-certified soil or tissue test verifies that there is a phosphorus deficiency. UF/IFAS Extension Seminole County provides free soil testing for residents.
Deflector shields are required when applying fertilizer with a broadcast or rotary spreader.
No fertilizer may be applied within fifteen (15) feet of any pond, lake, stream, canal, or other waterbody, including wetlands.

The overall goal of this ordinance is to minimize excess fertilizer runoff and protect the County’s natural water resources.
