Hosta Virus X: Mottled Leaves Mean Incurable Infection

Odd green mottling (light/dark patches) on hosta leaves signals Hosta Virus X (HVX). Once sold as variegated cultivars, these plants were recalled when the viral cause was discovered.

Critical Actions

• Remove and destroy all symptomatic plants immediately.
• Consider removing all hostas in the bed—virus spreads via sap on tools and insects.
• Do not share divisions for 3 years until sure remaining plants are clean.
• Sanitize tools with 10% bleach between plants.

HVX may not show symptoms for 2 years after infection. Vigilance is essential.
