When I started working at the University of Minnesota in 2004, there was very limited use of tall fescue as a turfgrass in Minnesota; this was primarily due to the perception that the winter hardiness of the species didn’t really measure up to other cool-season grasses. We started putting in turf plots of tall fescue right away, and noticed that it seemed to do just fine under most winter conditions.

Creeping Charlie (Glechoma hederacea L.), also called ground ivy, is a common herbaceous perennial native to the British Isles. Creeping Charlie has since spread to North America, and has been present in our landscapes for nearly 200 years. While some consider creeping Charlie to be a weedy species, others consider it to be naturalized, and some seed providers will sell this flower as a form of ornamental ground cover.
The 2017 Turfgrass Weed Control for Professionals manual is now available from the University of Minnesota Bookstore. This newly expanded guide provides weed identification and control information that turfgrass professionals can use to develop effective weed control programs for golf courses, athletic fields, sod farms, lawns, and other turfgrass systems.
Recently, we’ve received several questions regarding a new product offering from The Scott’s Company called “Roundup for Lawns.” There are several versions of this product, including both Northern and Southern grass options. The Northern grass product, for use on Minnesota lawns, states that the product “kills weeds, not the lawn.” Most of us are familiar with the original version of Roundup, which contains the active ingredient glyphosate, and we know that glyphosate is a non-selective vegetation killer- meaning that it kills most plants that it is sprayed on. So, how does Roundup for Lawns not kill the entire lawn?
