Count the sun hours. Under six hours of direct sun, plant St. Augustine. Over eight hours with real traffic, plant Bermuda. That single measurement decides this for most yards, and no amount of fertilizer overrides it.
Everything else — texture, water, mowing, cost — is a tiebreaker for the yards that sit in the middle.

How to actually measure your sun
Do not guess, and do not use the whole yard. Pick the shadiest area you still want grass in — usually the north side of the house or under a tree — and check it at 9 a.m., noon, and 3 p.m. on a clear day. Count the hours of direct sun that spot receives, not the yard's average.
Grass does not average. The shady corner will thin out and stay thin, and then you have a St. Augustine problem in a Bermuda lawn.
One more thing: check it in summer with the trees leafed out. A yard scouted in March is a different yard in July.
Where Bermuda wins
Traffic and recovery. This is the real advantage. Bermuda spreads by stolons above ground and rhizomes below ground, so a worn path or a dog's favorite turning point fills back in from all sides. A soccer-ball-sized bare spot in healthy Bermuda closes in a few weeks during the growing season.
Water. Deeper roots, better drought tolerance, and it survives dormancy and comes back. In a market with summer watering restrictions, Bermuda is the grass that survives the restriction.
That golf-course look. Cut short and dense, Bermuda is genuinely beautiful. Improved hybrids like Tifway 419, TifTuf, and Celebration are what sports fields and fairways use, for the same reasons your kids' yard would want them.
Where St. Augustine wins
Shade. It is the most shade-tolerant common warm-season grass, and if you have mature trees this is the entire conversation. Nothing else in the warm-season category comes close.
Mowing height and frequency. Cut at 3 to 4 inches with an ordinary rotary mower. No reel mower, no scalping worries, and one fewer mow a week in July.
Weed suppression. That thick, coarse canopy at 4 inches shades the soil so completely that most weeds cannot get started. A dense St. Augustine lawn needs very little herbicide, which is a real advantage nobody markets.
It looks lush. The wide blade reads as full and green in a way fine grasses do not.
The mower question that changes the budget
Bermuda looks its best below about an inch, and a standard rotary mower cannot cut that low cleanly — it scalps at the high points and leaves a scruffy, tan-flecked lawn.
So a proper Bermuda lawn often means a reel mower, and that is a $400 to $1,500 line item nobody mentions on the sales call. You can absolutely run Bermuda at an inch and a half with a good rotary and it will look fine. It just will not look like the picture that sold you on Bermuda.
St. Augustine needs no special equipment. Any mower that goes to 4 inches works.
Pests, briefly
Chinch bugs are the St. Augustine problem, and they show up as expanding yellow-brown patches in the hottest, sunniest part of the lawn — usually the strip along a driveway or south-facing wall. The damage looks exactly like drought stress, which is why people water more and make it worse.
Take-all root rot is the other St. Augustine issue, favored by high pH and stressed turf.
Armyworms hit Bermuda and can take a lawn from green to shredded in about two days. They also come back, so one treatment is often not the end of it.
Neither grass is fragile. Both have a known enemy, and knowing which one to watch for is most of the battle.
The variety matters as much as the species
Nobody plants "St. Augustine." They plant a variety, and the differences are large.
- Floratam — the historical default, vigorous, but it needs more sun than people expect. Not the shade pick.
- Palmetto, CitraBlue — selected for better shade performance and finer texture.
- Raleigh — better cold tolerance for the northern edge of the range.
On the Bermuda side, TifTuf is notable for drought performance, Celebration handles a bit more shade than most Bermudas and has good wear recovery, and Tifway 419 is the long-standing sports-field workhorse.
Ask which variety you are being quoted. "Bermuda" on an invoice is not an answer.
Our actual recommendation
Mature trees or a north-facing yard: St. Augustine, in a shade-selected variety. Do not fight it. Bermuda in shade thins for two seasons and then you pay for sod twice.
Full sun, kids, dogs, or a yard that gets used: Bermuda. The recovery from wear is worth more than any other single trait.
Full sun, low traffic, and you hate mowing: St. Augustine. Fewer mows, no reel mower, thick enough to keep weeds down.
Neither, if the area gets under about four hours of sun. No warm-season sod will thrive there. Put in mulch, a shade-tolerant ground cover, or a bed. We have told plenty of people to spend $300 on mulch instead of $1,800 on sod that was going to die, and we would rather do that than come back in eighteen months.
What decides it more than the grass
Preparation. A perfectly chosen variety on unprepared, compacted builder soil will disappoint you, and a decent choice on properly graded and amended soil will look great. Our guides to preparing a yard for sod and what installation costs cover that side of it.
Laredo Elite Sod & Turf installs Bermuda sod, St. Augustine, and everything in between across Laredo and the South Texas borderland, including the soil preparation and grading that decide whether it takes. We will walk the yard, count the sun, and tell you if part of it should not be grass at all.

- Bermuda Sod →
Bermuda sod is the right answer for most Laredo yards, and it is not close: hybrid Bermuda takes full sun and sustained triple-digit heat better than anything else that still looks like a lawn, uses noticeably less water than St. Augustine once established, and repairs its own wear as it spreads.
- Zoysia Sod →
Zoysia sod is what Laredo homeowners buy once they have owned a St. Augustine lawn and grown tired of feeding it — it grows slowly, so you mow less, and it grows densely, so it crowds out most weeds without a chemical program propping it up.
- Topsoil & Soil Amendment →
Topsoil and soil amendment is what you are really buying when you buy a lawn, because the four inches under the grass decide almost everything that happens afterwards. Laredo soil tests come back alkaline and high in free calcium carbonate, which is exactly why brand-new St.
- St. Augustine Sod →
St. Augustine sod is the grass to plant where a Laredo yard has real shade — under a mesquite, an anacua or a huisache, or on the north side of a two-story house where Bermuda thins out and quits by the second summer.
- Buffalograss Sod →
Buffalograss sod is the lowest-water lawn we install that still reads as a lawn, and in a city where summer irrigation is the largest line on a lot of water bills, that is the whole argument. It is a true North American native short-grass prairie species, it survives on a fraction of what Bermuda wants once established, and improved cultivars like Prestige, Topgun and Density hold a finer, denser stand than the wild type ever did.
Frequently asked questions
Which is better, Bermuda or St. Augustine?
Count sun hours on the worst part of the yard. Under about six hours of direct sun, Bermuda thins out and you want St. Augustine. Over eight hours with kids and dogs using the yard, Bermuda is far tougher. Between those, either works and other factors decide.
Does St. Augustine grow in shade?
Better than any other common warm-season grass. It manages on roughly four to six hours of direct sun, and shade-selected varieties like Palmetto and CitraBlue do better than Floratam, which genuinely needs sun despite its reputation as the default.
Is Bermuda harder to maintain than St. Augustine?
It needs more frequent mowing — every five to seven days in peak season versus seven to ten — and it looks best cut short, which often means a reel mower. In exchange it uses less water, recovers from damage faster, and shrugs off traffic that would thin St. Augustine out.
Which grass uses less water?
Bermuda, clearly. It roots deeper and tolerates drought stress by going dormant and then recovering. St. Augustine has shallower roots and browns out sooner under water restrictions. In a market with summer watering limits, that difference is a real cost.
Can you mix Bermuda and St. Augustine?
You can, but do not. They want different mowing heights, different water, and different fertilizer, so whichever one likes your conditions will slowly overrun the other and the lawn will look patchy the whole time. Pick one per area and use a hard edge between zones.
Which one repairs itself faster?
Bermuda, by a wide margin. It spreads by both above-ground stolons and underground rhizomes, so a damaged patch fills from every direction. St. Augustine spreads by stolons only, which means it creeps across the surface and takes noticeably longer to close a bare spot.
