Beginning October 1, 2013, homeowners and do-it-yourselfers will be required to follow University of Maryland recommendations when fertilizing lawns. Mandatory restrictions, similar to those imposed for lawn care professionals, apply:

  • A single application may not exceed 0.9 pound total nitrogen per 1,000 square feet and 0.7 pound of soluble nitrogen per 1,000 square feet.
  • Homeowners are prohibited from applying fertilizer to sidewalks, driveways or other impervious surfaces. Any product that lands on these surfaces must be swept back onto lawns.
  • No fertilizer applications within 15 feet of waterways. This setback is reduced to 10 feet if a drop spreader, rotary spreader with deflector or targeted spray liquid is used to apply fertilizer.
  • No lawn fertilizer may be applied between November 15 and March 1 and when the ground is frozen.
  • Fertilizers may not be used to de-ice walkways and driveways.
  • Do not fertilize if heavy rain is predicted.
  • Phosphorus may only be applied to lawns when indicated by soil test results or when the homeowner is establishing, patching or renovating a lawn.

Maryland Professional Lawn Care Manual

The Maryland Professional Lawn Care Manual is now available on the Maryland Department of Agriculture website.

Signed into law by Governor Martin O’Malley in 2011, Maryland’s lawn fertilizer law includes new requirements for fertilizer manufacturers, homeowners and lawn care professionals who must now be licensed and certified to apply fertilizers to properties that they manage. The law takes effect October 1, 2013 and is designed to protect the Chesapeake Bay and its tributaries from excess nutrients entering its waters from a variety of urban sources, including golf courses, parks, recreation areas, athletic fields, businesses and hundreds of thousands of suburban and urban lawns.

Regulations to implement the law were published in the Maryland Register earlier this year. Certification testing is slated to begin this fall and expected to be ongoing in order to address demand and busy schedules as the program begins. For more information on training classes and testing dates, visit the MDA website or contact MDA’s Urban Nutrient Management Program at 410-841-5959.

    I love to protect the waterways but many landscapers abuse waterways by blowing debris into our neighborhood streets and county roads. I can’t understand why there’s no Maryland Law against this practice. Really trashing our community’s, please observe! Thanks
