Cultural Practices


Grass Cutting Height

We recommend that you mow Centipede grass 1 1/2″ – 2″ high, St. Augustine grass 2″ – 2 1/2″ high and Bermuda grass 1″ – 1 1/2″ high. Mowing too high or too short can weaken your lawn’s root system causing your lawn to be more susceptible to insects, disease, drought, winter kill, etc.


Frequency of Mowing

The general rule of thumb is never cut more than 1/3 of the grass blade in one mowing. The frequency will vary from every other week in Winter and slow growing periods to once per week during the faster growing periods of Spring, Summer, and Fall.


Collecting Clippings

Latest research by various universities indicated that, under normal conditions, it’s not necessary to collect your grass clippings. This is based on the assumption that you mow your lawn on a frequent basis. If the grass gets too long between mowings, or if certain diseases are present, collecting clippings may be necessary.


Sharpening of Mower

To provide that super-manicured appearance, your mower should be sharpened a minimum of three times a year – Spring, Summer, and Fall.



If there are no restrictions on water and if you can water correctly, your lawn will be green all summer. Light, frequent sprinkling and late afternoon watering is not recommended. If you cannot water your lawn during a drought, the lawn will simply go dormant (brown) to protect itself. Then after it receives at least an inch of water, it will green itself up again within one to three weeks.


Correct Watering Procedures

If you are able to water during dry spells, set your sprinkler in each location for 1 to 2 hours. Do this weekly or until there is at least an inch of rain. If your time to water and/or water supply is limited, concentrate your efforts on one area, such as the front lawn, and allow the rest of the lawn to go dormant until it rains. Morning watering is always best.


Power Raking and Dethatching

This should not be done on Centipede grass and St. Augustine grass lawns because these grasses do not have rhizomes and this can kill it by removing it. To remove thatch we recommend: 1) mowing one notch closer and bagging clippings 2) raking hard with a leaf rake 3) core aeration. This should only be done when the grass is brown during the winter.
