Banana Magnolia Green Growth on Limbs: Lichens, Not Fungus

Banana Magnolia Green Growth on Limbs: Lichens, Not Fungus

Two banana magnolias (Michelia figo) with green growth on limbs, few leaves: the green matter is lichens or algae—harmless epiphytes indicating stress from drought or age, not a pathogenic fungus.

Revival

• Fertilize with balanced tree/shrub fertilizer.
• Water deeply during dry periods.
• Prune dead/dying limbs.
• Improve soil with compost mulch.

Key Point

Lichens don't harm the plant; they colonize slow-growing bark. Restoring vigor reduces lichen coverage naturally.
