Peruvian Apple Cactus Frost Damage: Wait, Then Prune

Patience First

Cereus repandus (Peruvian Apple) cold-damaged, upper columns rotting.

Protocol

1. Wait until all freeze risk passes (spring). Dead tissue protects live.
2. Cut to healthy green (firm, no brown).
3. Dust cuts with sulfur.
4. No sealant needed.

Winter Protection

• Styrofoam bowls (not cups) for large tips.
• Old towels/blankets work if secured.
• Incandescent lights under cover add heat.

Accept Some Loss

Extreme cold kills regardless. Prune cleanly in spring; new growth from areoles below cuts.
