Pinellas County’s Fertilizer Ordinance is intended to protect the water quality and natural habitats of creeks, lakes, and marine waters that receive runoff from our stormdrain system. Runoff of nutrients, primarily nitrogen and phosphorous, is contributing to poor water quality in our rivers, lakes, ponds, and Tampa Bay.
Excessive or improper use of fertilizer in landscapes is a significant source of excess nutrients to local waterways.
The following are details of the Retail Sale Section 58-482 that will help your business stay in compliance with Pinellas County’s Fertilizer Ordinance:
-
Effective June 1, 2011, retailers cannot sell any fertilizer that contains nitrogen or phosphorous between June 1 – September 30 each year. Summer-Safe Products for Pinellas County
