Quick Fixes
Step 1
Immediately relocate plant to stable warm environment (65-75°F/18-24°C)
Step 2
Lightly water soil if not frozen to rehydrate plant tissue
Step 3
Remove only completely black, mushy, or clearly dead foliage to prevent rot spread
Step 4
Cover outdoor plants with frost blankets if additional cold nights expected
Step 5
Ensure good air circulation to prevent fungal issues in damaged tissue
Step 6
Monitor daily for signs of secondary infections or further decline
Organic Treatment
Step 1
Move affected plants to a warmer location (65-75°F/18-24°C) away from cold sources immediately
Step 2
Lightly mist with water to gradually raise temperature and rehydrate stressed tissue
Step 3
Apply 2-4 inches of organic mulch around plant base for root insulation (outdoor plants)
Step 4
Wait 2-4 weeks to assess full damage extent before pruning - dead foliage provides insulation
Step 5
Use scratch test on woody stems to identify living tissue (green layer under bark)
Step 6
Prune only clearly dead or mushy tissue with sterilized tools once spring growth appears
Step 7
Apply compost tea or diluted seaweed extract as foliar spray weekly to support recovery
Step 8
Maintain consistent moderate watering - avoid overwatering stressed roots
