Upper Midwest Home Lawn Care for Cool Season Grasses
This lawn care calendar is a guide to maintaining lawns in the upper Midwest. It covers the general care needed to adequately maintain an average home lawn. In these lawns, the density of grass plants is sufficient to completely cover the soil surface such that no part of the underlying soil is left exposed or visible. The calendar is not intended to cover all aspects of lawn care, nor to cover all different growing conditions that may exist on a specific property. For additional information, see the list of lawn care publications available from the University of Minnesota Extension Service.
