Fertilizer restricted season begins June 1st

Sarasota County reminds the community that Fertilizer Restricted Season starts June 1, and is part of an effort to keep area waterways healthy.

Nutrient pollution is a widespread and challenging environmental issue for waterways throughout the county. You can help reduce nutrient pollution this rainy season by using environmentally friendly or alternative landscaping and lawn fertilizer from June 1 through Sept. 30.

According to Sarasota County Air and Water Quality Supervisor John Morgan, environmentally friendly fertilizers contain zero nitrogen and zero phosphorus. Excess amounts of these naturally occurring nutrients can create a harmful imbalance when washed away into storm drains and carried to local water bodies.

"Reducing the amount of nutrients collected by stormwater runoff helps protect natural habitats in area waterways, that receive runoff from our stormwater system," Morgan said, adding, "We are a growing community, and it will take a community effort to reduce nutrient pollution and continue having healthy waterways, beaches and more."

The Fertilizer and Landscape Management ordinance was enacted in 2007 to help preserve and protect natural resources and natural habitats in area waterways throughout the county. The amount of rainfall expected during the rainy season increases the likelihood of a surge of in nutrients in waterways. Excessive nutrients contribute to algae blooms, diminish water quality, and threaten aquatic life.

Community members can determine whether their fertilizer may be used during the restricted season, June 1 through Sept. 30, by checking the numbers. The first number represents nitrogen; the second is phosphorus, and the third is potassium or potash. Only fertilizers containing zero nitrogen and zero phosphorous may be used during the restricted season.

The following tips will help keep your yard looking great during the summer:

  • Use only fertilizers with zero nitrogen and zero phosphorous.
  • Apply iron, found at most garden centers, as an effective and environmentally friendly alternative to keep lawns green during the summer.
  • Use compost to enrich the soil.
  • Buy plants adapted to Florida's hot and humid climate.
  • Mow higher to encourage deep roots that resist fungus and pests.
  • Sweep grass clippings back into the yard, or recycle them in a compost pile. Do not allow grass clippings to be washed into storm drains.
  • Adhere to watering restrictions; even-numbered addresses water only on Tuesday and odd-numbered addresses water only on Thursdays.
  • Remember irrigation is prohibited between 10 a.m. and 4 p.m. daily, learn more about water restrictions here.
