The recommended height for blue grass lawns is 2 ½”-3″. Mow frequently so that no more than 1/3 of the grass height is removed during a single mowing. With this program, you will be mowing every 4-5 days in the Spring and every 7-10 days in the Summer.
Keep ryegrass, fescue and wheatgrass to a height of 2 to 3 inches. Buffalo-grass and blue grama do best if grown longer, or not mowed at all.
Remember to keep lawn mower blades clean and sharp for the best cut. Dirty, dull blades cause rough edges, which will turn grass blade tops brown, and damage the overall health of the lawn. Lawns bounce back better from mowing if irrigated afterward.
It is also recommended to use a mulching mower, that is one that leaves grass clippings on the lawn. This adds nutrients back to the soil, and helps the lawn retain moisture.
