Athletic fields are under significant stress during the playing season, which, in southern Ontario and most of Canada for that matter, is from the time the snow melts until it falls again. The predominate amount of play, however, is during the spring and fall months when most turfgrasses are slowly breaking from or entering dormancy. Play on already slowly growing grasses results in increased mortality and the appearance of thin or bare patches. These areas leave openings for opportunistic weeds to encroach on the field. The article discusses these challenges and the potential for supina bluegrass as an alternative species for overseeding athletic fields.
