Fertilizer Restrictions begin June 1. Based on a 2011 article, are the rules:
"To ensure the quality of our coastal waters, critical to our environment, economy, and recreation and protect from excessive nutrients that can cause harmful algal blooms, no fertilizers containing phosphorous and nitrogen can be applied during the period of June 1st through September 30th. Potassium and other soil amendments may be applied during the wet season period.
During the rest of the year, fertilizer containing Phosphorus and Nitrogen is limited. Fertilizer use is also prohibited within 10 feet of a water body, seawall, or wetland. And, if you use a fertilizer spreader, you are required to have a deflector shield to prevent nutrient spread into water body buffers and impervious surfaces. The application of nitrogen must be labeled as at least 50 percent slow- release."
