Proper Mowing Height
There is no one mowing height for all grasses, but each has it's optimal range. If they routinely cut lower than the ideal range they will not be as healthy and may begin to thin out and die. By mowing properly a deep root system develops, there is more leaf area for photosynthesis, and the blade shades the soil and gives the grass a better chance against weeds. Please follow the heights listed below.
Bluegrass and Fescue 3" or higher
Zoysia and Burmuda 2 to 2.5 inches
Mowing Frequency
Rule of thumb is to never cut more than one third of the leaf surface off at once. By mowing the lawn once a week you should be able to accomplish this. However, during peek growing times it may become necessary to mow every 4 to 5 days to comply with the rule of thumb.
Example: If desired height is 3" don't let the turf grow past 4.5"
Catching Grass Clippings
It has been commonly believed that clippings will create thatch build up. This is not true-the clippings are made up largely of water and will decompose within 6 weeks. The clippings will actually add fertilizer back to the soil. With today's restrictions on yard waste disposal and the improved mulching mowers it makes good sense to return the clippings to the soil. Be sure to avoid allowing the clippings to accumulate into piles. This will smother and damage the grass plant.
Dull Mower Blades
You should always have a sharp blade on your mower. Look for symptoms of a dull blade after mowing. If the tips are frayed and not a clean cut your blades need sharpening. The tearing of the tip injures the plant causing moisture loss and increases the possibility of disease and insect problems.
