Use lawn chemicals sparingly!  Lawn fertilizers & pesticides can wash into storm drains and pollute our local water ways.

LAWN SPREADERExcessive amounts of phosphorus, a component of lawn fertilizer, creates weed and algae growth, causing significant water quality problems.

  • Choose phosphate-free or organic fertilizers, and sweep up excess from paved areas.
  • Follow manufacturer’s recommended amounts – and never fertilize before a heavy rainfall.  Rain water can easily wash fertilizer down a storm drain.
  • The best times to fertilize are the late spring and early fall.
  • Make sure that you’re treating your lawn properly. Get your soil tested before you fertilize at UMass Extension.
