Best Mowing Height for Johnstown, CO in Late Spring

Quick answer: for most cool-season lawns in Johnstown and Northern Colorado, a higher mowing height around 3 to 4 inches is the safer choice in late spring. It helps the lawn handle heat, wind, and quick weather swings without getting stressed.

What that means in plain English

If your grass is growing fast, resist the urge to mow it down too short. Taller grass shades the soil, supports deeper roots, and usually looks better between cuts. In this region, short-cut lawns can dry out faster and show stress sooner.

Simple rule: never remove more than one-third of the blade in a single mow. Grass hates surprises almost as much as people do.

Why mowing higher usually works better here

When a shorter cut may make sense

There are a few exceptions. If the lawn is overly lush after heavy rain, has a lot of thatch buildup, or needs a reset after getting away from you, a slightly lower cut may help get things back under control. Keep it gradual, not dramatic.
