The City of Sanibel would like to remind all citizens, landscape and pest control professionals that frequent and unpredictable summer downpours increase the opportunities for nutrient run-off to enter our local waters. By not applying fertilizers containing nitrogen and phosphorus during the summer months, you can be part of the city's on-going effort to minimize local and regional nutrient pollution.
From July 1 to Sept. 30 it's in violation of Ordinance 07-003 to apply fertilizers containing nitrogen and/or phosphorous to lawns or landscape plants. Applications of these nutrients, where needed, may resume on Oct. 1 in accordance with the city's fertilizer regulations adopted by City Council in 2007.
For lawns and landscape plants that may need summer nutrients beyond those available in the soil, consider the following:
* Be Wise if You Fertilize! Prior to July 1, a fertilizer containing at least 50 percent Slow Release Nitrogen (SRN) may be applied at a rate not to exceed 1 lb. nitrogen/1000 sq. ft. As the name indicates, SRN is released slowly over time and will be available for uptake by plants all summer long.
* Nitrogen is responsible for plant growth. To achieve a "green-up" without unwanted growth, a micronutrient fertilizer containing iron may be used.
* When you mow, leave the grass clippings on your lawn. As the clippings break down, the nutrients will be recycled back to your lawn.
* Most Sanibel soils have enough naturally occurring phosphorus to support healthy plants. Unless a soil test indicates otherwise, save money and choose "no phosphorus" products year-round.
Because of the potentially severe impacts to water quality resulting from the misapplication of fertilizer during the summer months, City Code Enforcement, Natural Resources, and Sanibel Police are intensifying efforts to ensure compliance with the city's fertilizer regulations. Staff will be conducting frequent island-wide patrols for violators, including both citizen "do-it-yourself" applicators and professionals.
If using a professional fertilizer applicator, it is the homeowner's responsibility to ensure that the applicator has a City of Sanibel fertilizer applicator's endorsement (license). A list of city-licensed fertilizer applicators can be found at mysanibel.com/Departments/Building/Licensed-Contractors. Click on the "List of local licensed contractors." Licensed fertilizer applicators can be found at the end of the list (arranged alphabetically) under license class "Vegetation & Fertilizer" or "Fertilizer Only".
