How High Should I Mow my Lawn?

After you’ve done the standard maintenance on your lawn mower and decided that you’d rather spend hours mowing your lawn instead of having Yardly mow your grass for you, it’s important to determine the right height to mow your lawn at. While it’s easy to just guesstimate the right height and leave it at that, taking a bit of time to determine the exact height for your specific lawn can reap significant benefits. A correctly mowed lawn will mean less maintenance, better drought tolerance, and increased resistance to weeds.

Determining your grass type

The first step in finding out what height to mow your lawn at is determining your grass type. Most Edmonton lawns have cool season grass and most likely belong to one of the four grass species listed below. If you’re unsure of what kind of grass your lawn is, it’s safe to assume that it’s Kentucky Bluegrass, which is the most common grass type in the Edmonton area.

Mow your lawn on the higher end of the following height ranges for the best results.

  • Tall Fescue: 1.5 inches to 4 inches
  • Fine Fescue: 1.5 inches to 4 inches
  • Perennial Ryegrass: 0.75 to 2.5 inches
  • Kentucky Bluegrass: 1 to 4 inches

Mow high

Taller grass is conducive to deeper root systems and increased resistance to hot weather and droughts. For the best results, do not mow lower than 3 inches (depending on your specific grass type). While mowing on the higher end of the scale will likely mean an increased need for power raking and de-thatching in the spring and fall, mowing too low gives weeds exposure to sunlight and room to grow.

Another good rule of thumb is to never mow more than 1/3rd of the height of the grass blade when you’re mowing.
