Learn how to get rid of Virginia Buttonweed, one of the most common invasive weeds in the Southern U.S.
If you notice a low-growing weed with small white, star-shaped flowers spreading across your lawn, you may be dealing with Virginia Buttonweed. This invasive weed grows close to the ground and spreads quickly. Its leaves are light to medium green, sometimes yellowish, and grow directly opposite each other on slightly hairy stems. Each leaf is about half an inch to one inch wide.
This weed thrives in moist, wet areas, especially where drainage is poor or turf is thin. You’ll often find it in high-traffic areas or stressed lawns. Virginia Buttonweed is tough to control because it resists many common herbicides. It typically emerges in April or May and becomes strongest in mid to late summer, so early treatment is key.
If you already have Virginia Buttonweed, use a post-emergent herbicide. Selective herbicides target the weed while protecting your grass and work best when applied early in the season. Products containing 2,4-D or three-way-blends typically work well to control Virginia Buttonweed. Products containing Pyrimisulfan are also a good option. These are safe for most lawns when used as directed but make sure to check your product label for full application instructions.
Non-selective herbicides are stronger but will damage any plant they touch, so use them carefully for spot treatments. Apply herbicides during mild weather, below 85 degrees, with no rain expected for at least six hours. It may take one to three weeks to see full results. More stubborn and established areas will likely require repeat applications 2-3 times to eliminate the plant from the area.
Check your product label for best retreatment intervals and timing. To prevent Virginia Buttonweed, focus on lawn health. Improve drainage, water less frequently, mow higher, and thicken your turf with overseeding. Pre-emergent herbicides won’t fully stop this weed, but they can help control others, making management easier overall.
With proper timing and lawn care, you can keep Virginia Buttonweed under control. And it’s that easy with the expert help from DoMyOwn.com. Subscribe to our channel for more DIY and product videos.
