Chicago Park District Continues to Limit Use of Pesticides in Parks


Each spring, park patrons may see dandelions growing in their neighborhood parks throughout Chicago, signifying a chemical free park safe for play. For the seventh year, the Chicago Park District will partner with the Midwest Pesticide Action Center (MPAC) to limit its use of pesticides and offer park visitors safer and healthier parks.

In an effort to minimize impact on our environment, close to 90 percent of Chicago’s parks avoid spraying weed control chemicals.

“The Park District strives to keep our Chicago parks a healthy place for everyone to enjoy,” said Mike Kelly, Chicago Park District Superintendent and CEO. “We are encouraging all Chicago residents to follow the Park District’s example and use more natural lawn care techniques that keeps your lawn safe and healthy.”
The Chicago Park District mows turf grass to keep weeds down. Following natural lawn care basics, the Park District keeps the grass three inches high. This allows the roots to grow strong and access water deep in the ground. As a result, the taller grass naturally shades out some weeds. Even after cut, dandelion flowers persist and sometimes grow back overnight. However, the sight of dandelions indicates a safe space for all park patrons to play on.
“Midwest Pesticide Action Center is thrilled to include the Chicago Park District as part of our Midwest Grows Green network showing the district’s commitment to limit the use of pesticides to create healthy places to play,” says Ruth Kerzee, Executive Director of MPAC. “Follow these four simple and cost-effective tips, and you too can enjoy a beautiful yard safe for children, pets, and the environment.”
Four Natural Lawn Care Tips
  • Water Deeply and Infrequently: This encourages deep root growth. One inch per week is ideal. You can easily measure that amount by placing a cup in your yard while watering. When your sprinkler fills it one inch deep, your watering for the week is done. Water early in the morning to minimize disease problems.
  • Mow High: Keep you lawn mowed at three inches or higher. This will increase the root strength and naturally shade out weeds. Don’t mow your lawn unless needed. This creates healthy grass that can withstand drought and stay green longer.
  • Use Organic Fertilizer: Commercial fertilizers easily wash away, polluting nearby lakes and streams. Many contain toxic weed killers. Choose an organic fertilizer to capture and deliver nutrients in the lawn throughout the growing season. Keep grass clippings on the lawn as they are an excellent natural fertilizer.  
  • Weed Naturally: Proper lawn care maintenance naturally eliminates most weeds. Annual reseeding gives grass an advantage over weeds. Avoid using pesticides, as they can harm other beneficial living things such as bees, birds, and fish. The right tool makes quick work of weeding. After pulling weeds, use grass seed and soil to fill in the hole. Your lawn will be strong and healthy as a result.
