Sanibel's Fertilizer Information

Welcome to Sanibel's Fertilizer Information Website

In the past few years, the waters around Sanibel have become loaded with excess nutrients, prompting concerns about our marine life, our beaches, and our economy. The City of Sanibel is committed to addressing water quality issues on every front, from Lake Okeechobee to our own back yards. Fertilizer is one nutrient source that can be controlled.

In March 2007, the Sanibel City Council adopted a low nitrogen, low phosphorus Fertilizer Ordinance and began a concerted effort to encourage other municipalities to do the same.

This website is organized to help homeowners and professional applicators understand how to comply with the Sanibel Fertilizer Ordinance, with an important section outlining how to go fertilizer-free and still enjoy healthy plants. For those who choose to fertilize, we've included a simple calculator to help determine the proper amount to use based on square footage to be covered.

  • Fertilizer can be washed off by rainfall, going directly into the nearest body of water.
