White Webbing on Robellini Palm Trunks: Post-Freeze Fungal Growth

Thick white webbing on trunks of cold-damaged Robellini palms (pygmy date palms) is likely fungal mycelium colonizing freeze-injured tissue—not insects.

Options

Fungicide sprays (copper, etc.).
Organic: Atomic Grow (spray crown, trunk, soil drench).
Continue if no further freezes; palms often recover slowly.

Monitor new growth for health.
