At first glance, dichondra doesn’t look like much of a threat. Its small, round, kidney-shaped leaves are almost pretty—lush and green where your Bermuda or St. Augustine might be looking thin. But make no mistake: dichondra is a persistent and aggressive broadleaf weed that competes directly with warm-season turf in North Texas, and it exploits every cultural weakness your lawn has. Here’s how to identify it, why it thrives in DFW conditions, and how to actually get rid of it without killing your turf in the process.
What Is Dichondra?
Dichondra (Dichondra carolinensis and related species) is a low-growing perennial broadleaf weed native to the southeastern United States. Its stems creep along the ground and root at the nodes, forming a dense, ground-hugging mat that can reach several feet in diameter from a single plant. The leaves are distinctly round to kidney-shaped with a notch where the stem attaches—that shape is your primary ID marker. Flowers are tiny and inconspicuous, greenish-white, and easy to overlook. The plant spreads both by seed and by vegetative rooting wherever nodes contact moist soil.
You might have seen dichondra sold intentionally as a lawn alternative in certain climates—it does stay low and green, which is why some people initially tolerate it. In a North Texas warm-season turf lawn, though, it’s pure competition. It doesn’t handle foot traffic, drought, or heat as well as Bermuda, but it fills in thin areas aggressively during the growing season and holds on tenaciously.
Why DFW Warm-Season Turf Is Vulnerable
Dichondra loves the same conditions your lawn needs—warmth, moisture, and regular irrigation—which is what makes it such an effective invader of DFW turf. Several specific vulnerabilities let it get a foothold:
- Thin or shaded turf: Bermuda grass is a full-sun grass and thins out significantly in shaded areas. Dichondra tolerates partial shade better than Bermuda and moves into those thin spots first.
- Overwatering: Dichondra thrives in consistently moist soil. Irrigation schedules that keep soil too wet encourage dichondra while promoting disease in turf.
- Low mowing scalps: Mowing too short stresses turf and opens gaps at soil level that dichondra’s creeping stems fill immediately.
- Compacted edges and transition zones: Areas where turf is naturally thinner—along fences, under trees, at lawn borders—are where dichondra typically establishes first before spreading into healthier turf.
Dichondra vs. Other Round-Leafed Weeds in DFW
The kidney-shaped leaf with a notched base is your clearest identification tool. A few other weeds sometimes get confused with dichondra:
- Lawn burweed: Has dissected, fern-like leaves—nothing like dichondra’s smooth rounded leaves.
- Spotted spurge: Oval leaves (often with a dark spot), not round. Produces milky sap when stems are broken.
- Clover: Has three distinct leaflets per leaf; dichondra has a single round leaf per stem.
If you see a dense mat of perfectly round, kidney-shaped leaves spreading across your lawn, that’s dichondra.
Effective Control Methods
Dichondra control in North Texas warm-season turf requires selecting the right herbicide and understanding turf compatibility. Professional weed control programs approach it like this:
- Post-emergent broadleaf herbicides: Products containing 2,4-D, dicamba, or triclopyr are effective on dichondra and are safe for use in Bermuda grass. In St. Augustine, you need to be more careful—dicamba and high rates of 2,4-D can damage St. Augustine, so products formulated specifically for St. Augustine lawns (like those containing atrazine) are preferred. Always read the label for your specific turf type.
- Timing matters: Treat dichondra when it’s actively growing and temperatures are between 65 and 85°F. Treatments during heat stress (above 90°F) are less effective and increase the risk of turf damage.
- Multiple applications: Established dichondra mats with extensive root systems may need two to three applications spaced three to four weeks apart. The first treatment weakens the plant; follow-ups finish it.
- Pre-emergent for seedling prevention: Pre-emergent herbicides applied in early spring reduce new seedling establishment, cutting off one of dichondra’s spread mechanisms. This is a supporting strategy rather than a primary control tool since the perennial root system isn’t affected.
- Cultural improvements: Reduce irrigation frequency to dry the soil between waterings, raise mowing height slightly to thicken turf canopy, and address shade or drainage issues that are thinning the grass in affected areas.
The St. Augustine Complication
Many Arlington and DFW homeowners have St. Augustine lawns, and dichondra control in St. Augustine is more limited than in Bermuda. The good news is that atrazine—a staple herbicide in St. Augustine programs—provides solid control of dichondra when applied correctly. The bad news is atrazine has strict timing and label requirements, and misapplication near waterways or during rain is a concern. This is one situation where professional application genuinely outperforms DIY.
Long-Term Prevention
Once you’ve cleared dichondra from your lawn, keeping it out requires addressing the underlying conditions that let it in. That means a consistent fertilization program that keeps your turf dense and competitive, irrigation scheduling that avoids overwatering, shade management where possible, and a pre-emergent program to intercept seeds. A thick, well-fed Bermuda or St. Augustine lawn is your best long-term defense against every broadleaf invader, dichondra included.
Hamann’s Approach in North Texas
Hamann Lawn Care & Weed Control has been handling broadleaf weeds like dichondra across Arlington and DFW since 2006. We know which products are safe for each turf type, the right timing for the DFW climate, and how to address the cultural factors driving the infestation. For a close look at another creeping perennial weed that fights back just as hard, read our post on Virginia buttonweed—it shares many of the same habits and requires the same persistent multi-application approach to beat.
Don’t let dichondra turn your thin spots into a permanent takeover. The right treatment at the right time puts warm-season turf back in charge where it belongs.
