Maintaining a lush green lawn in Georgia's diverse climate can feel like an uphill battle against persistent weeds. From scorching summers to varying regional climates, numerous factors contribute to the unwelcome presence of these unwanted guests. Fortunately, these nuisance invaders can be managed. Armed with knowledge and strategic planning, you can transform your lawn into a vibrant haven free from these pesky intruders.
This guide explores some of the most common lawn weeds in Georgia, offering detailed descriptions, effective identification tips, and tailored control strategies for each, empowering you to reclaim your turf and enjoy a flourishing green space.
Crabgrass
This notorious summer invader thrives in warm, moist soil, spreading through aggressive tillering and wind-dispersed seeds.
Identification: Look for coarse, finger-like blades with reddish hues and crab-like seed heads in late summer.
Control: Apply pre-emergent herbicides in spring to prevent germination. Hand-pull young plants or use post-emergent herbicides labeled for crabgrass. Maintain healthy turf through proper watering and fertilization.
Dallisgrass
This perennial weed boasts flat, broad leaves with prominent white midribs and spreads rapidly through rhizomes and stolons, forming thick clumps.
Identification: Look for its distinctive seed heads resembling clusters of tiny green beads.
Control: Hand-pulling or digging up small patches is effective. For larger areas, consider using a systemic herbicide labeled for dallisgrass, but follow instructions carefully. Maintain a healthy lawn to discourage its spread.
Nutsedge
This weed stands out with its triangular stems and dark brown nutlets at the base. It spreads through underground tubers, making it a persistent foe.
Identification: Look for its distinctive triangular stems and dark brown nutlets at the base.
Control: Hand-pulling individual plants is effective, but ensure you remove the entire tuber. Herbicides labeled for nutsedge can be helpful, but repeated applications may be necessary.
White Clover
While some appreciate its white flowers, white clover can compete with desired grasses for nutrients and resources, quickly spreading and taking over and spreading.
Identification: Look for its characteristic trifoliate leaves with pale "V" markings and creeping habit.
Control: Hand-pulling or digging can be effective for small patches. Apply a broadleaf weed herbicide labeled for clover, but be mindful of nearby desirable plants. Maintain a healthy lawn with proper mowing and nitrogen fertilization to discourage its spread.
Chickweed
This low-growing weed thrives in cool, moist conditions. Georgia’s balmy climate in the cool season creates the perfect environment for these fast-growing invasive weeds to make their home on your lawn.
Identification: Look for its small, oval leaves and white star-shaped flowers.
Control: Hand-pulling is effective for small patches. For larger areas, apply a broadleaf weed herbicide labeled for chickweed. Maintain good drainage and proper mowing to discourage its growth.
Dandelion
While their sunny faces are charming, dandelions are notorious for their taproots and wind-dispersed seeds. Dandelions are among the most hardy weeds, able to grow in any climate and thriving in the warmth and humidity of Georgia.
Identification: Look for the familiar deeply lobed leaves and bright yellow flowers followed by fluffy seed heads.
Control: Hand-pulling is effective if done before seeds disperse. Alternatively, use a broadleaf weed herbicide labeled for dandelions.
Doveweed
This aggressive summer annual quickly establishes itself in warm-season turf, particularly plaguing residential lawns all over Georgia. This persistent weed germinates in late spring, waiting for soil temperatures to reach about 70 degrees Fahrenheit.
Identification: Look for dense, grass-like leaves and a vibrant green hue. Also, look for clusters of small blue to purple flowers that emerge from a short stalk near the leaf nodes to identify this weed.
Control: Few herbicides can effectively control it, making it one of the few weeds that would require professional assistance to find the right combination of herbicides and pre-emergents.
Annual Bluegrass
This tiny cool season annual weed might seem harmless, but its persistent nature and rapid spread can quickly turn your lawn into a bumpy, unsightly mess.
Identification: Look for leaves light green in color with a boat-shaped tip, growing together in clumps.
Control: Cultural practices, such as hand-pulling and mowing high, can reduce annual bluegrass, but herbicides are essential for superior control of this fast-spreading weed.
Goosegrass
Commonly found in high-traffic areas in compacted soil, this pesky weed spreads rapidly once it finds a home in your lawn. Goosegrass thrives with little water and moderate sunlight, making it a persistent problem for Georgia homeowners.
Identification: Look for grass with a silver and gray base, growing in a clump or a rosette with dark green leaves that are flat and slightly folded.
Control: Hand-pulling is effective for small infestations, but large infestations require more care. A series of post-emergent herbicides applied in stages is needed to eradicate this pesky weed.
Virginia Buttonweed
A deep-rooted perennial with spreading branches that usually proliferates in moist, wet, thin areas of turfgrass. It tolerates close mowing and is considered a very troublesome weed in Georgia.
Identification: Look for lance-shaped leaves with hairy stems and white star-shaped flowers.
Control: Properly applied post-emergent herbicides will control Virginia buttonweed in your lawn. More than one application is needed to get this pesky weed under control.
