Learn When to Time Your Last Mow of the Season

When it comes to the last mow of the season, the general rule of thumb is to mow low. But how low should you go? It really depends on a few factors.

Mowing the grass too short can hinder its ability to photosynthesize and make your lawn more vulnerable to freezing temperatures. On the flip side, leaving the grass too long can lead to matting and encourage snow mold.

Before you do that final mow, it's crucial to consider your specific grass type, as different types have different ideal cutting heights. Start by identifying your grass type and researching the recommended minimum height.

A simple rule to follow is to never cut off more than one-third of the grass blade in a single mowing session. For example, if you want to cut your grass down to 2½ inches but this requires removing more than one-third of its height, it's best to hold off on mowing low.

To minimize stress on the grass, lower the mower blades gradually over several mowing sessions leading up to your final cut, ensuring that the last mow isn’t too harsh on the turf.

As for timing, your cool-season grass will keep growing through the fall. Your last mow should occur once the grass stops growing for the season.
