Foxtail Palm Sap Flow After Severe Freeze: Signs of Stress or Death?

Bleeding Is Cold Trauma, Not Borers

Houston foxtail palms with sap running down trunks after snow + 20°F freeze: this is cold-stress bleeding, not borers. The internal membranes were damaged by extreme cold.

Protocol

Maintain irrigation.
No treatment stops sap flow.
Monitor crown for months.
Budget for replacement if crown rots.

Reality Check

Foxtails are marginally hardy in Houston. This event may have killed them. Survivors will be weakened for years.
