Don't fertilize your lawn

Most lawn fertilizers contain phosphorus. Runoff containing phosphorus can end up in local waterways and can stimulate large algae blooms which reduces oxygen levels. Alternatives: Leaving grass clippings on the lawn will provide nutrients. Or use your own compost as fertlizer or buy compost from stores.
