Henbit: Identification and Treatment in Georgia
Henbit is one of the first weeds to appear in late winter, covering dormant lawns with purple flowers. Learn how pre-emergent treatment prevents it entirely.
Weed profile
What Is Henbit?
Henbit is a winter annual that germinates in fall and is one of the first weeds visible in late winter. Its square stems and purple flowers stand out against dormant warm-season lawns.
Identification
How to Identify Henbit
Square stems (characteristic of mint family)
Small, tubular purple flowers in whorls around the stem
Rounded, scalloped leaves on short stalks
Upper leaves clasp directly to the stem without stalks
Most visible February through April when warm-season grass is still dormant
Commonly Confused With
Purple Dead Nettle
Purple dead nettle has triangular leaves with a purplish tint at the top. Henbit has rounder, greener leaves with more distinct scalloping.
Treatment
How to Get Rid of Henbit
Prevention
Fall pre-emergent application (September-October) prevents germination
Maintain healthy turf density going into fall
Avoid bare spots that give henbit easy establishment
Proper fall fertilization helps grass compete
Professional Treatment
Post-emergent broadleaf herbicide in late winter kills active plants before they set seed. Fall pre-emergent is the primary defense. Since henbit is an annual, preventing seed production for 1-2 years significantly reduces the population.

Why Professional Treatment Works Better
Most homeowners notice henbit in February when it’s already established and hard to control. Professional programs include fall pre-emergent that prevents henbit from ever appearing. Post-emergent treatment in late winter handles any breakthrough.

Common questions
Frequently Asked Questions About Henbit
Why do I have purple weeds in winter?
That’s likely henbit or purple dead nettle. Both are winter annuals that germinate in fall and become visible in late winter when your warm-season grass is dormant.
Will henbit die on its own?
Yes, henbit dies naturally in late spring as temperatures rise. But by then it’s already dropped seeds for next year’s crop. Treatment prevents that seed cycle.
When should I treat henbit?
Fall pre-emergent (September-October) prevents it. Post-emergent in February-March kills existing plants. Both are part of a comprehensive weed control program.
