Turfgrass Science News

For those of you who are wondering when to put your preemergent summer annual grassy weed herbicides down, NOW IS THE TIME. Soil temperatures are near 55 degrees in the upper profile and crabgrass will be germinating at 60 degrees. Any preemergent applications made after crabgrass has germinated will be ineffective. This application can be combined with fertility for increased density and spring turf greenup. Be sure to apply at the correct rate as directed by the herbicide and fertilizer label.

What a difference a year can make.  We certainly didn’t expect to be writing this report in the end of April while looking at snow on the ground across the state.  Now compare this to last spring, with golf courses opening in mid-March, and it gives us a little perspective on the influences that Mother Nature can dish out from season to season.  This winter has certainly gone on long enough, but the end is near (let’s hope).  We rewrote the record books last summer and fall with heat and drought extremes across the state, and this winter broke some records of its own.  How about these new T

Are you ready for spring or still enjoying the winter?  Either way, it’s time to start thinking about home lawn care again.  Last fall we were stressing the importance of maintaining moisture levels in your lawn amidst one of the worst droughts in Minnesota’s history.  In case you’ve forgotten, the months of August through November alone saw an eight inch precipitation deficit in the Twin Cities area.  This translates to approximately 70% below average precipitation for the fall period.  Many other areas of the state, mainly northwestern and southern Minnesota, were in a much worse situatio
