Key Takeaways
- DFW lawns generally need mowing from March through November, with the pace changing depending on grass type, season, and weather.
- Common Bermuda grass does best kept between 1 and 1.5 inches, hybrid Bermuda between 0.5 and 1.5 inches, while St. Augustine grass needs more height, between 3.5 and 4 inches, or 4 to 4.5 inches in shaded areas.
- Edging should happen every time you mow during spring and summer growth, often weekly, then taper off in fall and stop once the grass goes dormant.
- The one-third rule keeps grass healthy: never cut more than a third of the blade height in a single mow.
- Curious how clay soil and cycle-and-soak watering fit into a Frisco lawn care routine? That connection shows up further into this guide.
Keeping a lawn looking sharp in the DFW metroplex takes more than running a mower on the same day every week. Grass in North Texas moves through real seasons, from a slow winter sleep to a summer growth spurt, and the mowing and edging schedule needs to move right along with it.
You're about to learn exactly when to speed up, slow down, or pause mowing and edging based on the season, the grass type growing in the yard, and the weather rolling through DFW. Understanding these shifts helps prevent common problems like scalped grass, thin patches, and weeds creeping in over the driveway line.
DFW Mowing Season Runs March Through November
Warm-season grasses like Bermuda, St. Augustine, and Zoysia dominate lawns across the DFW metroplex, and all three wake up and go dormant on a similar timeline. Growth typically starts in March as soil temperatures climb and the grass shakes off winter dormancy. From there, the active mowing season runs through November, covering roughly nine months of regular care before the grass slows back down for winter.
March and November tend to act as transition months. Growth is happening, but slowly, so mowing every two weeks is usually enough before shifting to a weekly rhythm as temperatures rise. Between April and October, most healthy, irrigated lawns in North Texas need mowing on a weekly basis to keep pace with active growth. Watching the grass rather than the calendar is the more reliable approach, since a warm early spring or a stretch of unusually cool fall weather can shift these windows by a couple of weeks in either direction.
Grass Type Sets Your Mowing Height
Not all grass wants the same haircut. Mowing height directly affects how deep roots grow, how well a lawn holds up to drought, and how easily weeds find an opening to take root. Cutting Bermuda grass too tall or St. Augustine grass too short both create stress that shows up later as thinning or bare patches.
Bermuda Grass: 1 to 1.5 Inches (Common), 0.5 to 1.5 Inches (Hybrid)
Common Bermuda grass thrives when kept low, generally between 1 and 1.5 inches, while hybrid Bermuda varieties can be mowed even shorter, between 0.5 and 1.5 inches. This grass spreads aggressively through both roots and above-ground runners, and keeping it short encourages a denser, tighter turf that resists weeds and recovers quickly from foot traffic. Letting Bermuda grow too tall between mows can cause it to thatch up and develop a spongy, uneven surface.
St. Augustine Grass: 3.5 to 4 Inches (4 to 4.5 Inches in Shade)
St. Augustine grass takes the opposite approach, performing best at a height of 3.5 to 4 inches, and even taller, 4 to 4.5 inches, in shaded areas. This grass has broader blades and shallower roots than Bermuda, so extra height helps shade the soil, hold moisture, and protect the roots from DFW's intense summer heat. Cutting St. Augustine too short is one of the fastest ways to invite drought stress and disease, since the exposed soil dries out quickly and thins the turf.
Adjust Mowing Frequency by Season
Grass growth speeds up and slows down as temperatures shift throughout the year, and mowing frequency should track right along with it. A rigid weekly schedule makes sense for part of the year, but sticking to it in early spring or late fall usually wastes effort on grass that has not grown enough to need it.
Spring Green-Up: Every 10-14 Days, Then Weekly
As Bermuda, St. Augustine, and Zoysia grasses come out of dormancy in March, growth starts slow. Mowing every 10 to 14 days is typically enough during this early green-up window. As the weather warms through April, growth accelerates and the schedule should shift to weekly mowing to keep pace and avoid removing too much blade height in a single cut.
Summer Peak Growth: Weekly, Sometimes Twice
Summer heat pushes warm-season grasses into their fastest growth stretch. Weekly mowing remains the baseline through the peak months, but lawns receiving regular irrigation or steady rainfall can grow fast enough to need mowing twice in a single week. This is also where the one-third rule matters most: since summer growth is rapid, skipping even one scheduled mow can mean the next cut removes more than a third of the blade, which stresses the grass and slows recovery.
Fall Slowdown and Winter Dormancy
Growth begins tapering off as September and October bring cooler nights. Early September is a good time to fertilize before the grass starts winding down, and applying pre-emergent herbicide by mid-October helps head off weeds before winter. By November, mowing frequency can drop back to every two weeks. Once December through February arrives, most warm-season grasses in DFW go fully dormant, mowing pauses altogether, and attention shifts to leaf cleanup and prepping the yard for the next growing season.
Edging Follows Its Own Calendar
Edging keeps the line between lawn and hardscape crisp, defining the boundary along sidewalks, driveways, and flower beds. Skipping edging lets grass creep into spaces where it can crack pavement seams or smother garden beds over time, in addition to leaving a messy appearance. Like mowing, edging frequency should flex with the season rather than staying fixed all year.
Every 1-2 Weeks in Spring and Summer
Late spring through early summer brings the fastest growth of the year, especially for aggressive spreaders like Bermuda grass. During this active growing season, edging every time the lawn gets mowed, often weekly, keeps grass from creeping over hard surfaces and maintains a clean, freshly finished look. Early spring, roughly March through mid-April, and early fall are both considered prime edging windows since soil moisture tends to be moderate and turf is actively growing then.
Every 2-4 Weeks in Fall and Winter
Once fall slowdown sets in, edging frequency can taper off, dropping further as winter dormancy approaches and stopping altogether once the grass is fully dormant. Peak summer heat, typically June through August, is worth approaching carefully too, since edging during drought stress can damage turf roots along the cut line. The tool matters as well: string trimmers tend to need more frequent touch-ups than physical barriers like brick or stone edging, which naturally hold a line longer between maintenance visits.
Small Habits That Protect Lawn Health
A few consistent habits make a bigger difference than any single mowing schedule. Sharp mower blades matter more than the exact time of day, since dull blades tear grass rather than cutting it cleanly, which slows recovery and invites disease. That said, avoiding the heat of the day, generally between 10 a.m. and 4 p.m., still helps reduce stress on freshly cut grass.
- Mow mid-morning, between 8 and 10 a.m., once dew has dried, or in the late afternoon between 4 and 6 p.m.; mowing early, between 6 and 8 a.m. while dew is still present, can tear the grass and encourage fungal disease.
- Sharpen or replace mower blades regularly to prevent tearing and browning at the cut edges.
- Follow the one-third rule at every mow, never removing more than a third of the total blade height.
- Water deeply but infrequently, aiming for about 1 to 1.5 inches per week including rainfall, since this builds deeper roots than frequent shallow watering.
- Aerate once a year, particularly important in Frisco's clay-heavy soil, which compacts easily and can block water and nutrients from reaching roots.
Frisco's clay soil also affects watering strategy. The cycle-and-soak method, applying water in shorter bursts with pauses in between rather than one long soak, helps the water absorb rather than run off. Keeping soil pH between 6 and 7 gives most lawn grasses their best shot at absorbing nutrients efficiently. For warm-season grasses, applying a slow-release fertilizer after full green-up and during active summer growth, rather than while the grass is still coming out of dormancy, covers most of a lawn's nutritional needs across the year.
Matching Timing to Season Keeps DFW Lawns Healthiest
A lawn that looks consistently sharp throughout the year comes from paying attention to what the grass is actually doing each month, rather than from a single fixed schedule, whether that means slowing down mowing in November, speeding up edging in May, or pausing both altogether during winter dormancy. Grass type sets the baseline for height, season sets the pace for frequency, and DFW's clay soil and heat patterns shape the rest.
Homeowners who track these shifts tend to spend less time fixing problems like scalped patches or overgrown edges and more time simply enjoying a tidy yard. For those ready to put a seasonal rhythm into practice, following a regular lawn maintenance plan that adjusts with the calendar makes the whole process far less guesswork and far more consistent results.
