Can Houseplants Survive a Hard Freeze?

Assessing Cold Damage After Overnight Exposure

Plants left outside at -2°F (-19°C) or even -2°C (28°F) suffer severe cellular damage. Survival depends on duration, species, and root insulation.

Immediate Steps

1. Remove all damaged foliage: It won't recover and invites rot.
2. Keep soil drier than usual: Less leaf area = less water uptake.
3. Provide warmth and bright light: Above 60°F ideally.
4. Wait: New growth from roots may emerge in weeks if roots survived.

Reality Check

-2°F is likely fatal for most tropicals. -2°C may spare roots if pots were large and soil moist. Don't fertilize. Don't overwater. Time will tell.
