Treating Frost-Damaged Mediterranean Palms

Trim Only Fully Brown Fronds

Mediterranean fan palms (Chamaerops humilis) with brown leaves but green at the base and in some fronds are still alive. Green tissue = functioning tissue.

Action Plan

• Remove only 100% brown fronds.
• Spray crown with copper fungicide.
• Water properly (not daily).
• Wait for new growth from the crown.

Why This Species Recovers Well

Chamaerops is among the most cold-tolerant ornamental palms. If the crown survived, it will push new growth in spring. Patience and copper spray prevent secondary fungal issues.
