What Height for Last Mowing of the Year?

I get this question every year.  Some folks say:  “Take it down lower.”  Others say:  “Leave it long.”

My answer:  Keep on mowing at the same cutting height until your grass quits growing.

Recommended grass heights after you mow:

• 2-1/2 to 3 inches for Bluegrass, Ryegrass and Fine Fescue
• 3 inches for Tall Fescue and Buffalograss
• 3 to 4 inches for St. Augustinegrass
• 1-1/2 to 2 inches for Bermudagrass, Centipedegrass and Zoysia

 

I mow my Tall Fescue/Ky Bluegrass lawn at around 3 inches (after the cut)
