Lawn Fertilizers & Pesticides

Fertilizers, herbicides, and insecticides pollute our local waterways. Many Wisconsin residents use up to three times more fertilizer on lawns than is necessary.

Try to pull weeds manually whenever possible or spot treat problem areas if using chemical fertilizer. If you must fertilize your entire lawn, follow the summer bookend rule–only fertilize on Memorial Day and Labor Day, using phosphorus-free fertilizers. Minimizing the use of these chemicals ensures the water that reaches our rivers and lakes is clean and safe, but still keeps your lawn healthy and green.
