As you get ready for spring yardwork, the City of Roseville asks you to do your part to protect the city’s groundwater. The chemicals you apply to the lawn can seep into groundwater.
Runoff from fertilizer can enter the storm sewer system and wind up in neighboring lakes and ponds.
For the best results, use the minimum amount of fertilizer based on the manufacturer’s recommended rates and fertilize on a cool day before a rainfall or before irrigating, allowing the fertilizer to work into the soil.
Only buy fertilizers with the chemicals your lawn needs, and only buy enough to use for one season. To find out what chemicals you may need for your lawn, test your soil. The University of Minnesota Extension tests soil for a nominal fee. Visit soiltest.cfans.umn.edu for instructions on how to collect and submit soil samples. They will return soil sample results along with fertilizer recommendations in about three weeks.
Expired or unwanted lawn chemicals can be taken to a free Ramsey County Household Hazardous Waste collection site. For more information, visit RamseyRecycles.com/hhw or call 651-633-EASY (3279), answered 24/7.
