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