How High To Mow Your Lawn

Spring is just around the corner, and lawn mowers everywhere will soon be revving up for the first lawn mowing of the season.

That is great, but there is one question that is frequently asked by homeowners, "How high am I supposed to mow my lawn?"

There are some general rules that should help you have a great looking lawn this upcoming year!

Cool season grasses like Kentucky Blue Grass, Rye and Fescue are recommended to be mowed high.

Warm season grasses like Bermuda are recommended to be cut low.

More Specifics:

Cool season grasses like Blue Grass, Fescue, and Rye should be mowed as high as possible. The best is around 2 to 3 inches and no higher. If you cut any taller than that, the grass can flop over, and if you cut it too short, the grass is more susceptible to weeds, it dries out faster, and over all does poorly.

Warm season grasses like Bermuda should be cut around a height of 3/4 to 1 inch tall, which may require mowing one to three times per week.

Mowing at this height will encourage a dense, thriving turf that naturally blocks weeds. Healthy turf shades the soil so sunlight can't reach weed seeds ready to germinate, and a thick turf also minimizes the physical space available for weeds to become established.

If Bermuda is cut any taller than 1 inch, it will be thinner and straggly looking which isn't what you want. A good healthy lawn of Bermuda should look like a big, green, dense mat.
