Liriope Crown Rot: Identification and Management

Liriope (monkey grass) is famously tough, but crown rot caused by Phytophthora palmivora can strike, especially in wet conditions. Symptoms include yellowing foliage that pulls away easily with a blackened base.

Immediate Steps

• Stop all irrigation for the rest of the season.
• Fungicide drenches are effective but costly for large areas.
• Compost tea or a topdressing of compost may aid recovery.

Long-Term Prevention

If replanting is necessary, amend the soil with coarse sand (e.g., Pavestone Paver Leveling Sand) to improve drainage. Avoid overwatering and ensure good air circulation.
