Colorado homeowners have a narrow fall window for their final lawn cut - here’s when to stop mowing in 2026

Colorado’s mowing season can end sooner than many homeowners expect. According to the Farmers’ Almanac’s 2026 state-by-state mowing guide, mowing in Colorado typically winds down from late September through October. But that is only a general window, not a fixed deadline, because elevation, grass type, frost and local weather can change when a lawn stops growing.

When should Colorado homeowners stop mowing?

The best signal is the grass itself. Farmers’ Almanac recommends continuing to mow while the lawn is actively growing and says a useful test is to mow normally, wait 10 to 14 days and check whether the grass has barely grown. If it continues putting out significant new growth, it is not ready for its final cut.


A first frost also does not automatically mean mowing season is over. According to the outlet, cool-season grasses can remain green and continue growing after a light frost.

What will Colorado weather mean for mowing?

Colorado’s elevation can make fall conditions vary considerably from one location to another. The outlet also pointed out that temperature, elevation, first frost, soil temperature and local microclimates can all shift the final mowing date by several weeks.

For Colorado lawns, grass type matters too. Colorado State University Extension says buffalograss and blue grama are warm-season grasses, while bluegrass, ryegrass and fescue are cool-season options.

How to mow your Colorado lawn in fall

According to CSU Extension, the preferred mowing height for Colorado grass species is 2.5 to 3 inches, and there is no reason to cut turf shorter in late fall. The university also recommends removing no more than one-third of the grass height during a single mowing.

If weather causes the grass to become overgrown, CSU Extension recommends temporarily raising the mower height rather than cutting too much at once. It also advises keeping mower blades sharp and allowing grass clippings to return to the lawn when appropriate.

How much does lawn mowing cost in Colorado?

According to Housecall Pro’s 2026 pricing guide, standard residential mowing typically costs 45 to 90 per visit nationally, while hourly pricing is around 35 to 68.

GreenPal’s 2026 guide puts a typical weekly mowing visit at 45 to 55 for a standard 5,000–10,000-square-foot lawn, although size, terrain, frequency and local market conditions can change the price.

So the thumb rule for fall 2026 is: watch the grass, not just the calendar. If it is still growing, keep mowing; when growth has nearly stopped for 10 to 14 days, the lawn may be ready for its final cut.
