When is it okay to fertilize my lawn?

From October 1 to May 31, the Brevard County ordinance specifies that only fertilizers with zero Phosphorous, and at least 50% slow release Nitrogen are allowed in Brevard.

The ban lasts four months, June 1 until the end of September. During the summer rainy season, fertilizer on grass, turf, and lawns washes into streets and drains, making its way to the Indian River Lagoon and other waterways.

The nutrients in fertilizer (nitrogen and phosphorus) can lead to algae blooms and poor water quality.
