Controlling Liriope muscari Spread in the Lawn

Stop This Aggressive Spreader

Liriope muscari spreads by seed and rhizomes. Seedlings popping up in the lawn are common.

Control Strategy

1. Pre-emergent herbicide: Apply in early spring (when forsythia blooms) to stop seed germination.
2. Post-emergent: Spot-treat young seedlings in fall.
3. Deadhead: Remove flower spikes before seeds form.
4. Edging: Install deep barriers to block rhizome creep.

Timing Note

Pre-emergent prevents spring germination; post-emergent kills fall-germinated seedlings. Use both for full coverage. Avoid seeding lawn for 6 weeks after application.
