Proper mowing will have a tremendous effect on the appearance of your lawn. Height of cut, frequency of cut, and type of mower used are all important factors to consider when mowing a lawn. For the best appearance, turf should be maintained at its proper height.
As a general rule, turf should be mowed often enough that you are not removing more than 1/4 to 1/3 of the plant material. Example: If you are keeping your Bermuda grass at 1″, it will need to be cut at or before it reaches 1-1/2″. Removal of too much of the leaf blade can shock the turf.
