While you may be glad the mowing season is coming to an end, the fall is no time to cut corners on best practices for lawn mowing! The last mow of the season can set you up for a healthy lawn in the spring… or a lot of damage to undo.
When? The last mow of the season should happen around the time the grass stops growing—about when daytime temps drop below 50oF. That can be as late as early December in some parts of the South.
What about height? Mow your lawn to the recommended height for the variety, somewhere around 2 ½ inches for most varieties. Mowing too short can cause stress in cold temps, and leaving it too tall can invite snow mold. Even on the last mow of the season, don’t forget the 1/3 rule – don’t mow more than 1/3 of the total height at one mow.
Do I remove thatch? Thatch can help protect turf in the winter, and raking it can cause crown damage. Skip thatch removal for better turfgrass health all winter.
Do yourself and your lawn a favor – get the timing and height of your last mow just right, and enjoy the benefits next spring!
