Quick Answer: During active summer growth, St. Augustine grass in North Texas typically needs mowing every 7 to 10 days, tapering off in cooler spring and fall months, and little to no mowing once it slows down in winter. St. Augustine is commonly kept taller than Bermuda — generally 2.5 to 4 inches.
A Shade-Tolerant Lawn Grass
St. Augustine is a warm-season grass like Bermuda, but it's noticeably more shade-tolerant, which is why it's so common in DFW-area yards with mature trees — including many East Dallas properties. It still grows fastest with good sun exposure, heat and consistent moisture, typically peaking from late spring through summer.
As with other warm-season grasses, St. Augustine slows down as temperatures cool and can go semi-dormant or thin out in a hard winter, needing little to no mowing during that period.
Recommended Mowing Height for St. Augustine Grass
St. Augustine is generally mowed taller than Bermuda — commonly in the 2.5 to 4 inch range, depending on the specific cultivar. Mowing it too short is one of the more common lawn-care mistakes with this grass: St. Augustine has a shallower root system than Bermuda, and cutting it too low exposes the soil, stresses the turf and makes it more vulnerable to heat, drought and weed pressure.
Mowing Frequency by Season
| Season | Typical Mowing Frequency |
|---|---|
| Late spring–summer | Every 7–10 days |
| Early spring & fall | Every 2–3 weeks |
| Winter | Rarely, if at all |
St. Augustine generally needs mowing less often than Bermuda even at its peak, but exact timing still depends on rainfall, shade coverage and how the lawn has been fertilized.
The One-Third Rule Still Applies
Just like Bermuda, St. Augustine shouldn't have more than one-third of its blade height removed in a single mow. Because St. Augustine is already taller and more shade-sensitive, letting it grow too long between mows and then cutting it back hard in one pass is especially likely to shock the lawn — steady, regular mowing works better than infrequent, drastic cuts.
How KiteLine Schedules Recurring Mowing
KiteLine schedules recurring visits around the growth and condition of each property rather than applying one fixed interval to every lawn — which matters for St. Augustine's slower, shade-influenced growth pattern just as much as it does for fast-growing Bermuda.
