The single most common lawn mistake I see all summer is scalping. Here is the right height for each grass type once the heat sets in.
Somebody always wants to cut it real low so they can go longer between mows. In a Louisiana summer that fries the lawn. Taller grass shades its own roots and holds moisture.
The Right Height by Grass Type
St. Augustine wants three and a half to four inches. Centipede one and a half to two and a half. Bermuda one to two. Zoysia two to three.
The One-Third Rule
Never take off more than a third of the blade in a single cut. Weekly at the right height beats letting it get tall and then hacking it down.
Keep Your Blades Sharp
A dull blade tears instead of slicing, and torn tips brown out. I sharpen mine constantly. If you would rather not think about any of it, that is what I do every week.
