Strong Fertilizer Ordinance
Since June 2022, Orange County has regulated fertilizer use to prevent pollution from nitrogen and phosphorus, which can harm springs, lakes, and rivers by causing algae blooms and poor water quality. Over-fertilizing yards leads to excess nutrients flowing with rainwater into stormwater systems, damaging the environment.
Since taking office, I’ve prioritized responsible fertilization. In 2022, we passed a county ordinance to enforce these regulations. The ordinance restricts fertilizer application from June 1 to September 30, prohibiting nitrogen and phosphorus fertilizers during this period. From October 1 to May 31, phosphorus fertilizer can only be used if a soil test shows a deficiency, and at least 65% of nitrogen fertilizer must be slow-release. No more than 1 pound of nitrogen per 1,000 square feet can be applied at a time, with a maximum of 3 pounds per year.
Year-round, the ordinance requires maintaining a low maintenance zone near water bodies, prohibiting fertilizer application within 25 feet of waterways, and ensuring no fertilizer or grass clippings end up on streets, driveways, or in storm drains. Deflector shields must be used when applying fertilizer near streets and waterways. Fertilizer application is also prohibited during severe weather events. Additionally, commercial and institutional applicators must undergo training and display compliance decals, and retail businesses selling fertilizer must provide notice about the ordinance.
