IISG’s Lawn to Lake Program is focused on helping homeowners, landscapers, gardeners, and others adopt landscaping practices that reduce chemical runoff to local waterways, protecting and preserving those sources of water while maintaining thriving lawns and gardens.

There are a number of ways that everyone can keep local waterways clean while keeping their lawns green, and IISG has developed materials for homeowners, landscapers, and others to learn about how they can get involved.

“Don’t ‘P’ on your lawn” is a two-sided card (PDF) with healthy lawn tips and info on safe landscaping practices. The title is aimed at getting homeowners to watch out for phosphorus in their fertilizers, because phosphorus can lead to excessive algal blooms in waterways.
