How to get rid of henbit?

Henbit Control Strategies for Piedmont Lawns

Henbit is a winter annual weed that germinates in fall and becomes problematic in early spring. In Charlotte's climate, this weed is particularly aggressive in cool-season lawns during our mild winters.

Prevention Through Cultural Practices

The best henbit control begins with preventive measures implemented in late summer. Dense, healthy turf crowds out henbit seedlings before they establish.

• Maintain proper lawn thickness through regular overseeding
• Avoid bare patches where henbit seeds can germinate
• Keep grass height at 2.5-3.5 inches to shade emerging weeds
• Apply fall pre-emergent in October-November to block germination
• Ensure good drainage to prevent wet conditions that favor henbit

Early Spring Removal Options

1. Hand-pull small patches in March before flowering occurs
2. Apply selective broadleaf herbicides (MCPA or dicamba) in early March
3. Follow with follow-up applications 2-3 weeks later if needed
4. Post-emergent treatments work best on young plants before bolting
5. Remove pulled weeds before they go to seed to prevent future problems

Persistent henbit management requires consistent application of both cultural and chemical methods over multiple growing seasons in Charlotte lawns.
