Spot-treat the weeds you already have without damaging your lawn. Grass-safe chemistry for bermuda, zoysia, and St. Augustine.

The wrong herbicide will kill your lawn.

Once weeds have germinated, pre-emergent won’t help. Post-emergent herbicide kills them where they stand, but St. Augustine tolerates completely different chemistry than bermuda. The wrong product on the wrong grass will leave you with a dead yard.

Chris identifies the weed and the grass before he treats. Broadleaf vs. grassy, warm-season vs. cool-season, contact vs. systemic, each weed calls for a different product. That’s why a single “weed & feed” bag from the big-box store often makes things worse.

What you get.

Weed-specific products

Dallisgrass, nutsedge, clover, spurge, each gets the chemistry that actually works on it.

Grass-safe

St. Augustine tolerates what kills bermuda, and vice versa. Chris matches the herbicide to your turf.

Safe around pets and kids

Once the application has dried (typically 1–2 hours) the lawn is safe for pets and children.

Year-round windows

Winter weeds in January, broadleaf in spring, summer annuals in July, treatment doesn’t stop when the calendar flips.

By the weed.

Each weed below has its own chemistry, its own timing, and its own catch. Lumping them all under “weed control” is how lawns get damaged.

Crabgrass

The #1 weed in North Texas lawns. Annual grassy weed that germinates in spring when soil temperatures hit ~55°F at a 4-inch depth. The honest answer: pre-emergent is the only reliable tool for crabgrass. Once you can see it, the window for clean control has mostly closed. Post-emergent options exist but they’re hard on the surrounding lawn. If you missed pre-emergent this season, I’ll spot-treat the worst patches and set you up for next year.

Dallisgrass

Aggressive perennial grassy weed. Coarse texture, sticks up above the rest of the lawn, spreads from clumps that get bigger each year. Tougher than crabgrass because it survives multiple seasons. Plan on 2–3 well-timed treatments, typically spaced 3 weeks apart, to get clean control. There’s no one-shot product I trust on dallisgrass. Anyone who says otherwise hasn’t fought it long enough.

Nutsedge

Triangular stem, lighter green than your turf, grows visibly faster than the surrounding lawn after mowing. Spreads aggressively in moist or poorly drained spots. If you have nutsedge, you usually have an irrigation or drainage issue feeding it. Specific selective herbicides work, but repeat treatments are the rule, not the exception. I’ll often address the underlying moisture problem at the same time, otherwise the nutsedge just comes back.

Broadleaf weeds, clover, dandelion, spurge, henbit, chickweed

Wide-leaf weeds that aren’t grasses. Easier to control than the grassy ones because the chemistry separates broadleaf-killer from grass safely. Most broadleaf weeds brown out within 5–10 days of a properly timed post-emergent application. The trick is matching it to the season: clover and dandelion in spring, spurge in summer, henbit and chickweed in winter.

Winter weeds, poa annua, henbit, chickweed

Cool-season weeds that show up while warm-season turf (bermuda, zoysia) is dormant. They’re what makes a January lawn look weedy when the grass itself is brown. Pre-emergent in early fall is the cleanest fix. Missed that window, post-emergent options work but you’re treating a dormant lawn with care. Annual bluegrass (poa annua) is the most common. It dies on its own when temperatures climb, but a heavy patch of poa can still set seed for next winter.

“A weed dying in a patch of dead grass isn’t weed control. It’s damage control, and you’re doing it to yourself.”

Common questions.

Is weed control safe for my pets and kids?

Yes, once the application has dried, typically 1 to 2 hours. Chris uses professional products at labeled rates, the same chemistry approved for golf courses where thousands of people walk every day.

How fast will the weeds die?

Broadleaf weeds typically brown out within 5–10 days. Tougher grassy weeds like dallisgrass may need a second application 3 weeks later.

Do I need weed control if I already have pre-emergent?

Sometimes. Pre-emergent stops most warm-season weeds, but tough perennials and weeds that germinate outside the treatment window still come through. Post-emergent handles what slips past.
