How to Control Dollarweed, Nutsedge, and Other Stubborn Georgia Weeds
Maintaining a lush, weed-free lawn in the Atlanta suburbs is a point of pride for many homeowners, whether you’re a busy professional, a family with kids, or a retiree who values curb appeal and property value. Yet, stubborn weeds like dollarweed, nutsedge, and other persistent invaders can quickly turn your dream yard into a source of frustration. If you want a beautiful lawn without spending your weekends pulling weeds, this guide will answer your top questions about controlling these tough Georgia weeds- and show you why trusting local experts is the easiest path to a healthy, envy-worthy landscape.
What makes dollarweed and nutsedge so difficult to control in Georgia lawns?
Dollarweed (also called pennywort) and nutsedge thrive in the warm, humid climate of Georgia, especially in lawns with poor drainage or overwatering. Dollarweed spreads aggressively by seeds and underground rhizomes, while nutsedge grows from tubers (“nutlets”) that can survive even after the visible plant is removed. Both can quickly take over thin or weakened turf, making them notoriously hard to eradicate without a strategic approach.
How can I prevent dollarweed and nutsedge from invading my lawn?
Prevention starts with healthy lawn care habits. Dollarweed and nutsedge love wet, poorly drained soil and thin grass. Reduce your risk by:
- Watering deeply but less often, allowing the soil to dry between waterings. Lawns need about 1–1.5 inches of water per week, including rainfall.
- Mowing at the recommended height for your grass type-taller grass shades the soil and crowds out weeds.
- Aerating compacted soil to improve drainage and root health.
- Fixing low spots, broken sprinklers, or any drainage issues that cause puddles or soggy areas.
- Fertilizing appropriately for your turf type and only during the growing season, since overfertilizing can encourage weed growth.
What are the best ways to get rid of dollarweed and nutsedge without chemicals?
If you prefer to avoid herbicides, there are several cultural and organic methods you can try:
- Hand-pulling: Remove weeds when they are small, digging out as much of the root and rhizome system as possible. This is most effective for light infestations.
- Improve drainage: Aerate your lawn and address any water issues. Healthy, dense turf is your best defense against weeds.
- Spot treatments: For dollarweed, some homeowners have success with boiling water, baking soda, or vinegar as spot treatments, but these can harm grass and should be used carefully.
- Mulching: In shaded or garden areas, use mulch to block sunlight and prevent weed growth.
When should I use herbicides, and which ones work best in Georgia?
Sometimes, persistent weeds require targeted herbicide treatments. For dollarweed, selective broadleaf herbicides containing 2,4-D, dicamba, and triclopyr are effective, as are products with atrazine or imazaquin (check label for your turf type). For nutsedge, look for herbicides labeled for sedge control, such as those containing halosulfuron or sulfentrazone.
Apply herbicides in late spring or early summer when weeds are young and actively growing for best results. Always follow label instructions and ensure the product is safe for your specific grass variety. If your lawn is near water, choose products labeled as safe for aquatic environments.
How can I keep these weeds from coming back year after year?
Long-term weed control is all about lawn health and consistency. Here’s how to keep your lawn looking its best:
- Maintain a regular mowing and watering schedule.
- Aerate and dethatch annually to promote strong turf.
- Overseed thin areas to crowd out weeds.
- Monitor for early signs of weed growth and address them promptly.
- Work with a local lawn care company for customized, seasonally appropriate treatments and ongoing monitoring.
Why should I hire a professional lawn care service instead of doing it myself?
Controlling stubborn weeds like dollarweed and nutsedge can be time-consuming and requires knowledge of local turf types, climate, and safe herbicide use. A professional lawn care company can:
- Customize treatment plans for your unique lawn, soil, and weed challenges.
- Use safe, approved products and the right application timing for maximum effectiveness.
- Save you time and hassle, so you can enjoy your weekends and boost your property value without the work.
- Offer proactive communication, expert advice, and consistent service to keep your lawn healthy year-round.
