How to Control Dallisgrass in North Texas Lawns
Lawn care is a big deal in North Texas. Our hot summers and sporadic rain create ideal conditions for dallisgrass to thrive. Unfortunately, that same climate makes controlling dallisgrass more difficult, especially for homeowners who want a lush, weed-free lawn. And that’s why many people turn to professional weed treatment services to keep invasive grasses like dallisgrass under control.
Dallisgrass doesn’t just ruin the look of your lawn – it competes with healthy grass for nutrients, water and space. Left untreated, it can take over large patches that make your lawn uneven and patchy. That spells disaster for curb appeal and property value.
At Green Top Lawn Care we know that maintaining a healthy lawn concerns more than aesthetics, it’s also about fully enjoying your outdoor space and protecting your investment.
What Is Dallisgrass?
Dallisgrass is a coarse, clumping perennial weed that inhabits many lawns across North Texas. It’s notorious for its quick spread and resilience, especially in warm, humid climates. This unwelcome guest was originally introduced from South America, and has since found a home in many local yards.
You can spot dallisgrass by its wide, flat leaves and clumpy growth pattern. It tends to grow faster and taller than your lawn grass, making it stand out – and not in a good way. This weed also produces tall seed stalks with dark, purplish seeds that spread aggressively if not managed. Because dallisgrass has deep roots and tends to grow back yearly, it’s tougher to eliminate than seasonal weeds. It’s not just a lawn nuisance but a full-time invader, and that’s why it’s important to understand how to control weeds all year long to keep it from taking over.
Dallisgrass Treatment and Prevention
Controlling dallisgrass takes a combination of strategy, timing and consistency. Whether you’re dealing with a small patch of dallisgrass or a full-on takeover, here are the most effective ways to kick this stubborn weed to the curb and keep it there.
Manual Removal – If caught early, you can pull up dallisgrass by hand—just be sure to get the entire root—easier to do when the soil is moist. But for larger patches hand-pulling is not practical, since the weed has deep roots and rebounds fast.
Targeted Herbicides – To address widespread growth, selective herbicides like MSMA (in areas where it’s still permitted), or safer residential options such as sulfosulfuron work well. Timing is vital – apply in early spring or late summer before seed heads develop. Always follow label directions, or call in a Green Top Lawn Care professional for the best results.
Cultural Lawn Care – A healthy lawn is your best defense. Mow properly, water deeply (but infrequently), and fertilize on schedule. Aeration in the fall can also help. For reliable support, explore our North Texas lawn fertilization services to boost your grass’s health and weed resistance.
Pre-Emergent Prevention – Stop dallisgrass before it starts with a pre-emergent herbicide in late fall. Look for products containing dithiopyr or prodiamine. Green Top Lawn Care can help you choose the right treatment for your lawn’s needs.
