Lawn fertilizers, pesticides, yard clippings and leaves can wash into storm drains after a heavy rain fall and pollute our water ways.
- Make sure that you’re treating your lawn properly. Get your soil tested before you fertilize at UMass Extension.
- 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.
- Use lawn chemicals sparingly. The best times to fertilize are the late spring and early fall.
