The following is a chart for suggested mowing practices for Florida home lawns.

|7 – 14
|0.5 – 1.0
|3 – 5
|St. Augustine Grass
|2.5 – 3.5
|7 – 14
During the hottest months, the higher cut is recommended; grass can be mowed shorter in the cooler months.
Determining when to mow should be based on the growth rate of the grass, not on the calendar. To keep your lawn looking its best, remove only about one-third of the leaf blade each time you mow. Another good practice is to change direction with each mowing. This keeps the turf growing in an erect, upright position rather than leaning in the direction it was mowed. It also helps reduce turf wear and the possibility of scalping.
Making sure your rotary mower blade is sharp is probably the single most important requirement for proper mowing. A dull blade rips and shreds the grass instead of cutting it. Mowing with a dull edge makes the grass susceptible to several problems – such as brown leaf tips, disease, and insects. A good guideline for blade sharpening is to sharpen your rotary mower blade once each month. Try it! You’ll really notice the difference.
One More Tip
During the hottest months, it’s a good idea to water your lawn the day before you mow and then try to mow during the coolest part of the day. This minimizes the browning effect of summer mowing and decreases the time it takes the turf to heal.
