Grass Cutting Rules of a Green-Thumb
These Rules of a Green-Thumb will keep your grass looking good, healthy, vigorous, tolerating drought and prepared to fight pest invasions.
Most lawns should be mowed in the range between 2 to 4 inches - depending on the grass-type. Warm-season grasses - Bermudagrass, Zoysia and centipede grass should be mowed shorter 1-2½".
Creeping bentgrass - a cool season grass - is mainly used on golf
course greens and tees. It is occasionally used as a home lawn grass
and does best when cut short - ¼ to ¾ inches.
Cutting grass too short results in...
Taller grass plants...
Summer Lawn Mowing Tips: If you are growing cool-season grasses, it is a good idea to raise the height of cut during the heat of the summer. Cutting warm-season grasses low in the summer will improves quality. Prepare them for winter by raising the height in the fall.
Cut your lawn frequently...before it gets too long.
Proper lawn mowing removes no more than 1/3 of the total length of the leaf blade.
The 1/3 Rule: Cut your lawn often enough so no more than 1/3 of the grass height is removed at any single cutting. For example, If your mowing height is 2 inches - mow the grass when it is 3 inches tall.
You may have to mow every three to four days during the spring/early summer when the grass is actively growing. But only once every seven to 10 days when growth is slowed by heat, drought or cold.
Warm season grasses - such as zoysia or Bermudagrass - should be cut at lower heights. The more frequent you mow lawns that are maintained short the nicer they will look.
Bentgrass is a cool-season grass that is commonly used on golf
greens. It is sometimes used as a home lawn grass. Bentgrass makes a
very attractive lawn when mowed short and frequently. It get's ratty
and puffy when mowed high.
Sharpen Your Lawn Mower Blades
Sharp blades give your lawn a clean, manicured look.
Dull blades tear, shred and bruise grass leaves instead of cutting them cleanly. The frayed leaves turn brown and then white, making your lawn look ugly.
Cutting grass with dull mower blades increases water loss and leaves entrances for disease.
Don't bag the clippings! Leave them on your lawn to decompose naturally. Grass clippings decompose quickly and are a source of nutrients and organic matter. Did you know that about 25% of the nitrogen in your lawn fertilizer is removed with grass clippings?
Keep grass clippings on the lawn and out of streets, driveways and sidewalks. Sweep or blow them back into your yard. Grass clippings are full of nutrients - they are basically fertilizer - and when left on sidewalks, driveways or in the road they will wash into storm drains and find their way into our rivers and lakes.
Debris from yard waste that ends up in our waters is a bigger source of phosphorus water pollution than lawn fertilizers.
