The Minnesota Department of Agriculture (MDA) has created new publications on the best management practices (BMPs) of turfgrass pesticides. These BMPs provide guidance on pesticide use for lawn care for homeowners and lawn care companies to help protect water resources, humans, and non-target organisms including pollinators.
Sam Bauer and Parker Anderson of the University of Minnesota have created an infographic that profiles different turfgrass species for use in Minnesota home lawns. This is a great resource to educate homeowners on the characteristics, maintenance, and recommendations of these grasses for specific uses such as under low maintenance or shade conditions.

Many plant enthusiasts have observed difficulty planting some plant species around black walnut trees. Black walnut trees naturally excrete chemicals into their environment to make themselves more competitive. This negative plant-on-plant interaction is known as allelopathy, and is more common in multiple plant species than was once previously thought.
There have been a few reports (Bertin et al., 2009; Bertin et al., 2003) of natural weed suppression in certain fine fescues (Festuca spp.).

NASA scientist Cristina Milesi estimates that there is three times the amount of turfgrass in the United States as there are acres of irrigated corn . When we consider that the rate of grass seed density required for turf can be up to 6 lbs per 1000 sq.ft, one can imagine the enormous quantity of seed needed to plant all that turf! Most of that planted grass seed is, at least here in the Midwest, Kentucky bluegrass. However, there is a grass genus that has gained interest and may one day be used just as much or more as Kentucky bluegrass.
Did you know that many Minnesotans with irrigation systems over-water their lawns? University of Minnesota Extension and the Metropolitan Council have created a new educational video on home irrigation efficiency that illustrates how homeowners can save water, while still having a great-looking lawn.
