Peruvian Apple Cactus Decline After Move and Cold

10-Foot Cereus peruvianus: Blackening Top After Transport in 45°F

Top 6 inches bent during move, wrapped in plastic, plastic came off. Propped up, but turned black, dried, cut off. Now another 12 inches blackening, lower trunk light green with purple blotches. Watered sparingly (2 teacups every 2 weeks). Moved from west window.

Assessment

• Likely cold damage during transport (exposed to freezing air).
• Let heal before cutting more.
• Water only when soil dry; overwatering worsens rot.
• Random spreading spots may indicate systemic failure.
