PROPER LAWN MOWING TECHNIQUES

Follow These Simple Lawn Mowing Tips for Your Colorado Lawn: Mow the Lawn Tall and Mow Regularly


Small Changes to Lawn Mowing Techniques Will Make Huge Improvements

Organo-Lawn does not offer lawn mowing as a service but we do understand how to properly mow a lawn and how the techniques can dramatically improve a lawn's appearance and overall health.

  • For only the first and the last mow of the Colorado lawn care season the recommended mowing height for Colorado's cool season grass types is 2.5 inches.
  • It is extremely important to raise the mower height to 3 inches or taller from the middle of April through September.
Set The Lawn Mower on The Highest Setting!

Often the highest setting on most mower types is 3 inches. Mowing the grass at 3 inches or taller will prevent diseases, promote deep digging roots, help the grass conserve water, improve turf density, and improve turf color.

A lawn should be mowed frequently enough that no more than 33% of the foliage is removed at one time. This one minor change of mowing on the highest setting will make a major improvement in the overall health and beauty of your lawn.

The Taller You Mow the Deeper The Roots Will Dig!

Grass root depth and mowing height are correlated. Grass roots will dig about 3 times as deep as the height the lawn is mowed.

  • For instance if a lawn is mowed at 1 inch then the grass roots can dig to be about 3 inches deep.
  • If the lawn mowing height is raised to 2 inches tall the grass roots can dig to about 6 inches deep.
  • If the mowing height is raised to 3 inches tall then the grass roots can dig to be about 9 inches deep.

A very small change in mowing height makes a huge difference in lawn appearance, drought resistance and overall health.

Mowing the lawn tall is one of the best organic weed controls. Lawns that are mowed tall naturally with have fewer weeds than lawns that are mowed short.


What are the three main reasons that most homeowners mow their lawns too short.

  1. A lot of people think a short lawn looks better than a taller lawn. The problem is a short lawn uses more water, has more weeds, is thinner, has shorter roots, and is not a dark green.
  2. Golf courses mow the grass very short. Most people think golf courses look nice, but what they don't realize is that golf courses have different types of grass than what is in a residential lawn. The golf course grass types can handle being mowed short while most residential lawns cannot.
  3. The lawn mower settings are confusing. There are about 6 different settings on a lawn mower. We suggest mowing on the highest setting. Most homeowners don't know the height of the lawn mower settings and instinctively think the middle setting is the best choice. The middle setting is typically around 2 inches which is too short.
How often should the lawn mower blade be sharpened?

Lawn mower blades should be sharpened once every five mows. An easily noticeable sign of a dull blade is when the tips of the grass are ripped, turning them white. One final suggestion for how to properly mow a lawn is to rotate the direction of the cut every mow. For instance, mow lengthwise one week, width wise the next, and diagonal the following. By following these instructions you will put less stress on your lawn, helping create the lush green lawn that you desire.

Lawn Mowing Made Simple:
  • Mow the lawn at least once per week.
  • Set your lawn mower on the highest setting. This should be 3 inches or taller.
  • Sharpen the blade about once per month. If you are seeing white tips on the lawn then the blade needs to be sharpened.
  • Mulch the grass clippings, as long as they don't clump up all over the lawn
  • Rotate the mowing direction every week.
    • Mow Length-wise
    • Mow Width-wise
