Managing Resurrection Fern and Spanish Moss on Trees

“Air ferns” like resurrection fern and Spanish moss are epiphytes—they grow on trees for support only and do not parasitize them. However, heavy growth can be unsightly and may indicate the host tree is stressed.

Control Options

• Copper fungicide: Products like Hi-Yield Copper Fungicide can suppress growth with 4–5 applications spaced 10–14 days apart.
• Physical removal: Labor-intensive but effective. Wear gloves and pull gently to avoid bark damage.
• Avoid herbicides: They can harm the tree.

Long-Term Management

Improve tree health: water during drought, fertilize appropriately, and ensure good air circulation. Healthy trees naturally host fewer epiphytes. Accept that complete eradication is difficult; focus on management.
