Lawn Care and Landscape Professionals are also prohibited from applying fertilizer between Nov 1 and April 1.

• This law now requires landscape business owners to attend a one time educational fertilizer program.
  
  
• This program is designed to inform landscapers about the law and the potential environmental impact of nitrogen pollution and to encourage the use of the practical guidelines of Best Management Practices (BMPs) in landscaping.
  
  
• Upon completion of the educational program, attendees receive a certificate directly from Suffolk County which is a requirement of a home improvement contractors license application or renewal. (See Fertilizer education opportunities.)

The law states the following:

• The Suffolk County Department of Economic Development and Planning will be furnishing informational signs and brochures to all establishments that sell lawn fertilizers. The signs must be displayed within 10 feet of the fertilizer display area.
  
  
• If an establishment has more than one fertilizer display area, and it is not continuous, then additional signs and brochures must be displayed in both areas within 10 feet of each display area.
