Lawn Care and Product Management

When lawn care products are applied at the proper rates and timed so they do not rapidly run-off or infiltrate the soil, they pose a relatively minor threat to groundwater. On the other hand, excessive use or poor application timing can result in these products contaminating groundwater. Everyone needs to do their part by following recommended rates and guidelines for using lawn care products to help protect our community drinking water supply.

Fertilizers and lawn care chemicals can impact groundwater and drinking water sources. Managing your lawn care routine can prevent them from becoming a threat to our waters. See a few tips below:

  1. Test your soil to determine the correct mix of fertilizer needed for your lawn.
  2. Read all chemical labels - follow instructions and treatment rates.
  3. Fill fertilizer spreaders and chemicals in areas that can be properly cleaned p. Keep away from streets and storm drains.
  4. Wait until grass is actively growing before applying fertilizers.
  5. Mow your grass to a height of 2 1/2 to 3 inches.
  6. Do not apply fertilizers to frozen ground or when inclement weather is in the forecast.
