Sago Palm Cold Damage at 11°F: Assessment and Recovery

Hardiness Limit Exceeded

King and Queen sagos tolerate brief drops to 20°F. At 11°F, fronds yellow and die. The critical question: did the crown (growing point) and roots survive?

Immediate Steps

1. Move container to a frost-free area (garage, indoors).
2. Cut off all yellow/brown fronds at the base.
3. Keep soil barely moist; do not fertilize.
4. Watch the crown center for a new green spear.

Hardening Off

Next winter, acclimate gradually: reduce water, stop fertilizing by September, and protect with frost cloth + heat lamp when forecasts approach 25°F.
