Is Overseeding With Supina Bluegrass a Viable Option

Overseeding Options Traditionally, Kentucky bluegrass (Poa pratensis, which I will refer to as KBG), with its preferred dark green colour and ability to withstand traffic due to its rhiPrevious studies have examined the use of perennial ryegrass (Lolium perenne L., subsequently referred to as PR) for overseeding into pre-existing fields. Both Elford et al. (2008) and Rossi (2004) found that frequent overseeding with high rates of perennial ryegrass could result in a more uniform stand with fewer bare ground patches and weeds. However, this practice may lead to decreased winter survival rates of the fields since perennial ryegrass is susceptible to extreme weather conditions. For this reason, there is merit in investigating other turfgrass species that could perform well under trafficked conditions. Supina bluegrass (Poa supina) is native to the European Alps and has been bred... stress during the playing season, which, in southern Ontario and most of Canada for that mat-
