Cutting Column Cactus: Where to Cut for Best Rooting

Follow-Up: Cut Location

7.5-foot column cactus with 41-inch top growth hitting ceiling.

Cutting Advice

• Cut mid-stem (not at woody base, not at tip).
• Woody tissue won't root; tip is too soft.
• Let callus 3 weeks.
• Pot in cactus mix, water when dry.
• Roots in 2+ months.

Ongoing Management

Remove ~2 feet yearly to avoid annual ceiling battles. Bright light (15 hrs/day) reduces stretching.

Grow light supplement if window light insufficient.
