Every North Texas homeowner knows the feeling. You're looking at a lawn that should be green and uniform, and instead there are patches of something else entirely — faster-growing, coarser, or a different shade of green that makes the whole yard look uneven and untended. Weeds in Grapevine and the DFW area are a year-round battle, and unlike most lawn problems, they don't wait for you to get around to addressing them.
Understanding what's growing in your lawn — and what actually controls it — is the difference between spending money on products that don't work and executing a program that systematically eliminates weed pressure season after season. This guide covers the most common lawn weeds in North Texas, how to identify each one, and what treatment approach works for your specific situation.
North Texas creates ideal conditions for a wide range of weeds throughout the year. The long, hot growing season gives warm-season weeds like crabgrass and nutsedge a lengthy window to establish and spread. The mild, wet winters give cool-season weeds like henbit and annual bluegrass the foothold they need in dormant turf. And the clay-heavy soils common across Grapevine, Southlake, and Colleyville create compaction conditions that stress turf and open gaps for weeds to exploit.
The other critical factor is that most weeds don't care what time of year it is — there's a weed germinating in DFW lawns in every month of the year. Spring brings crabgrass and dallisgrass. Summer brings nutsedge and spurge. Fall brings henbit and annual bluegrass. A lawn that's only managed during the growing season always has weeds establishing themselves in the off-season gaps.
Effective weed control in North Texas is a year-round program, not a single spring treatment.
CrabgrassCrabgrass is the most widespread and recognizable weed problem in DFW-area lawns. It's a summer annual — meaning it germinates in spring, grows aggressively through summer, produces thousands of seeds, and dies with the first fall frost. What it leaves behind is a brown, dead patch where it occupied space, and the seed bank it deposited will produce more crabgrass the following spring.
Crabgrass is coarser and lighter green than Bermuda grass, and it grows in a low, spreading, star-shaped pattern that makes it highly visible in an otherwise uniform lawn. It thrives in exactly the conditions that stressed, thin turf creates: bare spots, closely mowed grass, and areas where the turf density has dropped. A thick, healthy Bermuda or St. Augustine lawn makes it significantly harder for crabgrass to establish because there's no exposed soil for germinating seeds to reach sunlight.
How to control it: Pre-emergent herbicide applied before soil temperatures reach 55°F in late winter is the primary defense. Once crabgrass has established, post-emergent herbicides can be effective on young plants, but larger, more established crabgrass is much harder to eliminate. Lawns with significant crabgrass infestations may require physical removal and resodding of affected areas combined with a comprehensive pre-emergent program.
Nutsedge (Nutgrass)Nutsedge is arguably the most frustrating weed in North Texas lawns — partly because of how aggressively it grows, and partly because many homeowners don't initially recognize it as a weed at all. It looks like grass. It grows in your lawn just like grass. The difference is that it grows significantly faster than turfgrass, creating visible raised patches that stand out days after mowing. Its color is a yellowish-green that looks distinctly off against the deeper green of Bermuda or St. Augustine.
The identifying detail is the stem: nutsedge has a triangular stem you can feel by rolling it between your fingers. It grows in groups of three leaf blades from the base. And it spreads through underground tubers (nutlets) that can survive in the soil for years — which is why nutsedge that's been treated comes back, and why controlling it requires patience and specialized products.
Nutsedge thrives in overwatered areas and spots with poor drainage, making it particularly common in low points of the yard, near downspout discharge areas, and along irrigation head zones that apply too much water.
How to control it: Nutsedge requires a post-emergent product specifically labeled for sedge control — standard broadleaf herbicides have no effect on it. Treatment is most effective in late spring through summer when nutsedge is actively growing. Multiple applications are typically necessary, and addressing the drainage or irrigation issue driving the problem is essential for long-term control.
DallisgrassDallisgrass is a coarse-bladed perennial grassy weed that grows in distinct, expanding clumps with tall seed stalks that tower above your turf. Unlike crabgrass, it doesn't die in fall — it goes dormant and comes back each spring from the same root system, slightly larger and more established. Over time, a single dallisgrass clump can expand into a significant patch that's clearly visible in any lawn.
Dallisgrass is common in Grapevine and Colleyville and is particularly difficult to control because there is no pre-emergent that provides reliable protection against it, and most selective post-emergent options have limited effectiveness. It tends to appear in the same spots year after year.
How to control it: Post-emergent herbicide applications targeting dallisgrass in late fall while it's still actively growing are the most effective cultural approach. For severe infestations, non-selective spot treatment (which will also kill surrounding turf) followed by resodding affected areas is often necessary. Dallisgrass is one of the weeds where professional diagnosis and treatment makes the most significant difference, because misapplied products can damage the surrounding turf without effectively eliminating the weed.
HenbitHenbit is a winter annual broadleaf weed that most Grapevine homeowners encounter in early spring — those low-growing, purple-flowered plants spreading across the lawn as dormant grass is just beginning to green up. What makes henbit frustrating is that by the time you see it blooming in February and March, it's already been growing since the previous fall.
Henbit has distinctive square stems (a characteristic of the mint family), circular hairy leaves, and spreads aggressively through DFW lawns during the off-season when warm-season grasses are dormant and not competing for resources. By spring, it can cover significant lawn area, making the property look neglected exactly when the neighborhood is starting to come back to life after winter.
How to control it: Fall pre-emergent application — timed when soil temperatures drop toward 70°F in September or October — is the primary defense. This blocks henbit seeds before they germinate and prevents the winter establishment that produces the visible spring problem. Post-emergent broadleaf herbicides applied to young seedlings in fall or early spring are also effective. Once henbit is in full flower in March, control becomes less effective and it's better to focus on fall prevention for the following season.
Annual Bluegrass (Poa Annua)Annual bluegrass is a fine-bladed cool-season grass that looks distinctly out of place in a North Texas Bermuda or St. Augustine lawn. It germinate in fall, grows through winter, produces seed heads in late winter and spring, and dies as temperatures rise in late spring. The problem is the gap it leaves behind — bare patches in the lawn in May that are immediately available for warm-season weed germination.
Poa annua is particularly common in closely mowed, irrigated turf, and it produces abundant seeds that can persist in the soil for years. In dense neighborhoods across Grapevine, where neighboring lawns can seed into each other, annual bluegrass pressure can be significant year after year.
How to control it: Fall pre-emergent application is the primary defense — the same timing that targets henbit also provides coverage against annual bluegrass. Consistent fall pre-emergent programs that interrupt the seed cycle year over year gradually reduce poa annua pressure, though it rarely disappears entirely given the ongoing seed pressure from surrounding landscapes.
Dandelions and Broadleaf WeedsDandelions, clover, chickweed, and other broadleaf weeds appear throughout the season in North Texas lawns and are generally the easiest of the common weeds to control. Selective post-emergent broadleaf herbicides containing 2,4-D, dicamba, or triclopyr are effective against most broadleaf species and safe for Bermuda, St. Augustine, and Zoysia when applied correctly.
Dandelions have deep taproots that make hand-pulling unreliable — unless you remove the full root, the plant regenerates. Herbicide treatment in fall or early spring, when the weed is actively transporting nutrients to the root, is most effective. Clover often indicates low nitrogen levels in the soil — addressing the fertility issue reduces its competitive advantage.
Every weed control professional in North Texas will tell you the same thing: the single most effective long-term defense against weeds is a dense, actively growing, well-maintained lawn. Weeds exploit the gaps — bare spots, thin turf, mowing-stressed grass, areas recovering from heat or drought damage. Remove the gaps and you remove most of the opportunity.
This is why consistent weekly mowing at the correct height, proper seasonal fertilization, and professional lawn care that maintains turf density are weed prevention strategies as much as they are aesthetic ones. A Bermuda lawn maintained at proper height with consistent weekly service has dramatically less weed pressure than one that's cut too short, mowed inconsistently, or stressed by improper care.
Pre-emergent programs prevent weeds from germinating. Post-emergent programs eliminate weeds that are already established. But a thick, healthy, consistently maintained lawn makes both programs more effective and reduces the treatment needed over time.
Texterra Lawn & Landscaping's weekly maintenance program is built around the turf health principles that prevent weed pressure from developing. Consistent mowing at the correct height for your grass type, hard-edge edging that eliminates the transition zones where weeds establish along hard surfaces, and thorough weekly service that keeps your lawn dense and actively growing — all of it works together to reduce the conditions weeds exploit.
For comprehensive pre-emergent and post-emergent weed control programs tailored to your specific grass type and weed history, Texterra can connect you with trusted local specialists. And for the weekly maintenance that keeps your turf dense, competitive, and less vulnerable to weed invasion throughout the season — that's exactly what we deliver, visit after visit, across Grapevine, Southlake, and Colleyville.
