Fertilizer & Landscape Information
Incorrect use of fertilizer, excessive irrigation, and poor landscape debris management can allow nutrients to leach into the groundwater and wash into stormdrains that flow to creeks, lakes, Tampa Bay, or the Gulf of Mexico. This causes harmful algae blooms, which lower oxygen levels and lead to fish kills. Nutrient pollutions can be controlled with your help. An ounce of prevention is worth a ton of cure!
- June 1 – September 30: Skip the fertilizer during the summer rainy season.
- Near waterfront: Fertilizer-free zone begins 10 feet back from the top of the slope towards any seawall or body of water.
- Landscape maintenance: Blow grass clippings, sand, and leaves back in the yard.
- Irrigation: Reclaimed water is liquid nutrients. Overwatering causes leaching of nutrients. Conserve water and skip the fertilizer. Select the link below the reclaimed water map image to see if you can reduce your fertilizer use.
