Cold Damage on snake plant
What's Happening
Snake plants are sensitive to temperatures below 50°F/10°C. Cold damage occurs from exposure to freezing temperatures, cold drafts, or sudden temperature drops. Symptoms include mushy, softening leaves, browning, wilting, and cellular rupture. The plant's succulent tissue stores water which freezes and damages cell walls. However, rhizomes often survive even when leaves appear dead.
How to Fix It
- 1
Bring plant indoors immediately if temperature drops below 50°F/10°C
- 2
Trim away all mushy, damaged, or dead leaves at the base with sterilized shears
- 3
Inspect roots: if firm and white, the plant will likely recover; if black/mushy, trim affected roots
- 4
Repot in fresh, dry well-draining soil if roots were frozen or soggy
- 5
Place in warm (65-80°F), bright indirect light location away from cold drafts
- 6
Withhold water for 2-4 weeks to prevent root rot during recovery
- 7
Be patient - new growth from rhizomes can take 1-3 months to appear
How to Prevent It
Monitor weather forecasts and bring plants indoors before first frost. Keep indoor temperatures above 50°F. Avoid placing near cold windows, air conditioning vents, or drafty doors during winter. For outdoor plants, use frost blankets or move to sheltered locations.
