Are Maryland's summers to warm for Kentucky Bluegrasses?

Asked April 19, 2018, 2:29 PM EDT

I know that many garden supply stores sell different types of bluegrass, but I read a U of Pennsylvania article statitng that Kentucy bluegrasses don't to well in temperatures above 75 deg. F. Obviously Maryland's summer temperatures often exceed that for weeks at a time. What knowledge do you have regarding the use of bluegrass in our region with respect to it's viability in the summer months

The recommended lawn grass in Maryland is a mixture of turf-type tall fescue.

Kentucky Bluegrass does not do as well. It needs more fertilization and has disease issues in our climate. It is sometimes used in sod farming to help 'knit' the grasses together due to how it grows, but at only about a 5% rate.

Here is our University of Maryland Extension publication: Lawn Establishment, Renovation and Overseeding. You can learn more about this starting on page 2:
