Rated 4.8 Across 20+ Reviews


Maintaining a lush green lawn in Georgia's diverse climate can feel like an ongoing battle against tenacious grassy weeds. These unwanted guests compete for water, nutrients, and sunlight, threatening the health and beauty of your turf. However, with knowledge and strategic planning, you can transform your green space into a flourishing haven free from these grassy invaders.

This guide delves into five common grassy weeds plaguing Georgia lawns, offering detailed identification tips, proactive prevention strategies, and effective control methods for each.


Bahiagrass in a lawn.
  • Identification: Coarse, blue-green blades with prominent veins and seed heads resembling miniature wheat stalks. Spreads aggressively through stolons and seeds, forming dense mats that crowd out desired grasses.
  • Prevention: Maintain a dense, healthy lawn with proper mowing (3-4 inches) and fertilization. Avoid overwatering, as Bahiagrass thrives in moist conditions.
  • Control: Hand-pulling is feasible for small patches. For larger areas, consider selective herbicides labeled for Bahiagrass. Remember, multiple applications might be necessary for complete control.


Crabgrass in a lawn.
  • Identification: Low-growing, reddish-hued clumps with coarse, finger-like blades. Crab-like seed heads emerge in late summer, readily dispersing seeds for rapid spread.
  • Prevention: Practice early prevention with pre-emergent herbicides applied in late spring or early summer. Maintain a dense lawn through proper mowing and watering.
  • Control: Hand-pull young plants before seed production. For established infestations, use selective herbicides labeled for crabgrass. Apply in late spring or early fall while temperatures are still warm.


Dallisgrass in a lawn.
  • Identification: Clumping perennial with flat, broad leaves featuring prominent white midribs. Seed heads resemble clusters of tiny green beads. Aggressively spreads through both rhizomes and stolons, forming thick, difficult-to-remove patches.
  • Prevention: Maintaining a healthy, dense lawn is crucial. Consider pre-emergent herbicides in early spring, but remember these won't control established plants.
  • Control: Hand-pulling is ineffective due to the extensive root system. Repeated applications of selective herbicides specifically targeting Dallisgrass are often necessary. Consult a lawn care professional for a tailored control plan.


Seeds of bermudagrass weeds.
  • Identification: Warm-season grass with long, wiry stolons and rhizomes that can quickly invade cool-season turf. Features distinctive finger-like blades and reddish seed heads.
  • Prevention: If you have a cool-season lawn, choosing the right grass type for your climate is critical. Avoid overwatering, as Bermudagrass thrives in dry conditions.
  • Control: Eradication can be challenging. Selective herbicides targeting Bermudagrass exist, but multiple applications and professional guidance are often recommended.


Goosegrass in the soil.
  • Identification: Flat, broad leaves with pointed tips and prominent veins. Produces spiky seed heads resembling miniature burrs, readily attaching to fur and clothing for dispersal.
  • Prevention: Maintain a healthy lawn and consider applying pre-emergent herbicides in early spring. Regular mowing prevents seed production.
  • Control: Hand-pulling young plants before seed heads develop. Organic methods like boiling water can be used cautiously on young plants. For larger infestations, use selective herbicides labeled for goosegrass.

Additional Weed Control Tips

  • Early identification and intervention are key. The sooner you address grassy weeds, the easier it is to control them.
  • Regular monitoring of your lawn is crucial for proactive weed management.
  • Always follow label instructions carefully when using herbicides to ensure safety and effectiveness.
  • Consider consulting a lawn care professional for personalized advice and treatment plans, especially for persistent or widespread infestations.

By understanding these pesky grassy invaders and employing the right strategies, you can reclaim your lawn and enjoy a thriving green space that reflects your dedication and care. So, arm yourself with knowledge, choose the right tactics, and watch your lawn transform from a battlefield into a verdant paradise!
