It is one of the oldest and most often-asked questions when it comes to lawn maintenance: How high should I cut my grass? The answer varies dependent on the season, but we have some tips on the ideal mowing heights by season below!

Spring/Fall Mowing

The optimal height for a cool-season grass is generally about 2-½”* Each time you mow, you should only be removing about the top ⅓ of the grass blades. That being the case, a good time to mow your lawn is when it’s about 3-⅔ inches high. We especially recommend that you stick to this height in the fall, as your grass will soon become dormant and cutting too low could potentially cause damage.

*Some experts believe that keeping your lawn grass as long as 3 inches tall during spring or summer can help to inhibit crabgrass. The theory, here, is that the crabgrass will be shaded out and not able to survive.

Summer Mowing

The same height applies in the summer, but on the hottest days of the summer, you may consider going to a higher setting on your mower to avoid stressing your lawn during this hot, dry part of the season.

Why is 2-½” an Optimal Grass Height?

In terms of your lawn, the objective is to find balance. Mowing your grass is like giving your lawn a nudge to start growing! When you let your grass grow longer, you’re passing up opportunities to stimulate new grass growth and making your lawn healthier and more beautiful. Cutting your grass too short, on the other hand, can stress your lawn and stunt new growth.

How Often Should I Mow?

This question is asked just as often and really has the same answer .You shouldn’t plan a mowing schedule, but instead plan a schedule to check your lawn’s height. As each part of the growing season is different, and rainfall levels are a factor, you may find you need to mow more often or less often dependent on conditions.
