Sudbury's Eco-Friendly Lawn Program

Green water at Carding Mill Pond

Help protect Sudbury's ponds and waterways by minimizing the impact of lawn care on the surrounding environment.


Chemicals used to promote growth and make your lawn green can wash off into nearby ponds and waterways and turn them green also by promoting the growth of unwanted algae and aquatic plants. Dense weeds and algae reduce oxygen in the water, which can harm fish and other aquatic life. "Green water" is also much less attractive for scenic and recreational uses.


Voluntarily comply with the following tips for creating a green lawn without creating green ponds and waterways.

  1. Use fertilizer sparingly, sweeping any overspray back onto the lawn to prevent runoff. Test your soil to apply only the amount of fertilizer needed.
  2. Use pesticides and herbicides sparingly, spot treating affected areas only.
  3. Try using organic lawn care products and methods. If you use a lawn service, ask them about switching to organic products.
  4. Mow 2.5 to 3 inches high with a sharp blade to encourage dense growth and deter weeds.
  5. Mulch lawn clippings on the lawn to lessen the need for fertilizer; in autumn compost the clippings for use the following year.
  6. Do not over-water your lawn; instead water deeply and less frequently, timing watering to avoid evaporation and directing spray to avoid runoff.
  7. Re-seed bare spots with drought-tolerant varieties of grass to minimize the need for watering.

Display a lawn sign to show your participation in the program and encourage your fellow Sudbury residents to do likewise.


A limited number of lawn signs will be available on a first-come, first-serve basis. They have been approved for display starting during Earth Week through the end of May, and again at the start of autumn, from September 1 through September 30.
