Natural history, identification, and growth habit
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?
Do you have a weedy lawn or a lawn currently composed of high maintenance turfgrass species and you want transition to something that takes less work and is better for the environment? If so, please have a look at this series of 7 videos sponsored by the Minnesota Turf and Grounds Foundation. This process is best accomplished in the fall from August 15th to September 15th, but spring conversions are possible as well. Following the last step, erosion control, you'll want to be sure to keep the seedbed moist throughout the germination period, which is generally 7-14 days.
The winter of 2016/17 was anything but normal and it feels like we’re getting used to saying that every spring. An exceptionally warm November, over an inch of rainfall (and therefore ice) on Christmas, golf in mid-February, a general lack of snow cover, and temperatures more than 10 degrees below average in early-March are just a few of the ups and downs that we’ve experienced in the Twin Cities metro region this winter. So, what does this mean for turf and golf courses, you might ask?
