Sago Palm Tan Spongy Growth: Likely Environmental Exudate, Not Disease

The tan spongy growth on the trunk below the leaves is not a recognized disease or insect. It’s likely a plant exudate responding to environmental change (repotting, light, humidity).

Action

• Monitor periodically for changes.
• Stones in containers aid drainage/weight—no need to replace if removed.
• Ensure bright light and avoid overwatering.

If the plant looks healthy otherwise, no treatment is needed.
