A Greener Lawn Starts Naturally

True Blue Gardening: Feed Your Lawn, Not the Lake

A lush, green lawn may look healthy, but traditional fertilizers can have unintended consequences for Torch Lake and the surrounding waterways.

When fertilizer is applied to lawns, rain can wash excess nutrients into nearby lakes, streams, and wetlands. These nutrients, particularly phosphorus and nitrogen, can fuel algae growth, reduce water clarity, and disrupt the natural balance of aquatic ecosystems. Healthy lakes thrive when nutrient levels remain low. (See graphic below)

The good news? Your lawn may need less fertilizer than you think.

Build Healthy Soil Naturally

• Leave grass clippings on the lawn to return nutrients to the soil.
• Top-dress with compost to improve soil structure and fertility.
• Mow high (3–4 inches) to encourage deeper roots and drought resistance.
• Water deeply but infrequently to promote healthy growth.
• Consider planting native species that require little to no fertilizer once established.

If You Fertilize

• Have your soil tested first.
• Choose phosphorus-free products unless a soil test indicates a deficiency.
• Follow application instructions carefully.
• Never apply fertilizer before heavy rain.
• Keep fertilizer off driveways, sidewalks, and roadways where it can wash directly into storm drains.
