How often should you mow an Austin lawn? A season-by-season guide
Weekly, every two weeks or monthly? It depends on your grass type and the time of year. Here’s how to decide.
“How often should I mow?” sounds like a simple question, but in Austin the honest answer is: it depends on your grass and the month. Mow too rarely in June and you’ll scalp the lawn when you finally catch up. Mow too often in January and you’re just stirring up dust. Here’s a practical way to think about it.
Start with the one-third rule
The most useful rule in lawn care is to never remove more than about one-third of the grass blade in a single mowing. Cutting more than that stresses the plant, exposes stems that can’t photosynthesize well, and opens the soil to sun and weeds.
So mowing frequency isn’t really about the calendar. It’s about how fast your grass grows past its ideal height. If your St. Augustine is kept at about 3 inches, you’d want to mow before it gets much past 4½ inches.
Know your grass type
Most Austin lawns are one of four warm-season grasses. Each has a different preferred height:
| Grass | Typical mowing height | Notes |
|---|---|---|
| St. Augustine | About 2½–4 in | The most common Austin lawn. Prefers a higher cut, especially in summer and in shade. |
| Bermuda | About 1–2 in | Fast-growing in full sun. Looks best mown low and often. |
| Zoysia | About 1–2½ in | Dense and slower-growing. Higher end of the range in shade. |
| Buffalograss | About 2–4 in, or left longer | Native and drought-tolerant. Needs far less mowing. |
These ranges are general guidance. Your exact height depends on shade, irrigation and how the lawn has been kept in the past. If you’re unsure what grass you have, a good crew can tell you on the first visit.
A season-by-season guide for Austin
Spring (March–April): waking up
Warm-season grasses green up as soil warms. Growth starts slowly, so every two weeks is often enough early in spring, moving to weekly as growth picks up. This is also the time for a spring reset: clearing winter debris and cutting back ornamental grasses.
Late spring to early fall (May–September): peak growth
With heat, sun and any rain or irrigation, St. Augustine and Bermuda can grow quickly. Weekly mowing is usually the right call for well-watered lawns. During hot, dry spells growth slows, and it helps to raise the mowing height a little, since taller grass shades the soil and holds moisture better.
Fall (October–November): slowing down
As temperatures drop, growth slows and many lawns can move back to every two weeks. Leaves from many trees start falling in late fall, so regular mowing also helps mulch light leaf cover. Heavier leaf fall needs clearing so it doesn’t smother the grass.
Winter (December–February): mostly dormant
Warm-season grasses go dormant and brown in cold weather. Mowing is mainly about tidiness: an occasional visit for weeds, leaves and edges. Winter is a good time for hedge shaping, bed planning and getting ahead on mulch.
So, weekly, every two weeks, or monthly?
- Weekly suits most sunny St. Augustine and Bermuda lawns from roughly April to October.
- Every two weeks suits shady or slower lawns, or the shoulder seasons in spring and fall.
- Monthly generally only works for slow-growing lawns (like Buffalograss) or in winter. In summer, a month of growth means you’ll break the one-third rule.
Small habits that make a big difference
- Keep blades sharp. Dull blades tear grass, leaving ragged, browning tips.
- Change direction. Alternating mowing patterns prevents ruts and grass leaning one way.
- Leave short clippings. Short clippings break down quickly and return nutrients to the soil.
- Skip soaked lawns. Mowing wet grass tears it and ruts soft soil. Wait for it to dry.
- Follow the current watering schedule. The City of Austin publishes watering rules that can change with drought stages. Check the latest before adjusting irrigation.
The short version
Mow often enough that you never take off more than a third of the blade, at the right height for your grass. In Austin, that usually means weekly in summer, every two weeks in spring and fall, and occasional tidy-ups in winter.
