Broken Cactus: Propagate the Top, Regrow the Base

Columnar Cactus Breakage: Two Plants from One

A broken cactus column cannot be reattached, but both pieces can become healthy plants.

Top Piece (Broken Off Section)

1. Lay on its side in dry, shaded spot for several days until cut end calluses (hard, dry, slightly sunken).
2. Plant in fresh cactus soil, deep enough to stand upright.
3. Wait 4 weeks for roots. Don't water until rooted.
4. Result: New plant identical to original top.

Base (Remaining Rooted Section)

1. Trim jagged break to clean, angled cut.
2. New growth will emerge from the cut edge within months.
3. Often produces multiple branches = fuller plant than before.

Key Points

• Callusing is essential—prevents rot entry.
• Cactus soil must drain instantly (add extra perlite/pumice).
• Bright light for both pieces.
• Patience: cacti operate on slow timelines.

Many cactus collectors intentionally "behead" plants to create offsets. Your accident is an opportunity.
