Reader Question

I have a very overgrown Anthurium in an 8-inch pot that I'd like to separate into 6 or 8 smaller pots. The plant has developed aerial roots and thrives in southeastern light. Can I simply cut sections off and plant those aerial roots directly into a potting soil/bark mixture?

Expert Advice: Prune, Don't Divide

Congratulations on your thriving Anthurium! While division might seem logical, separating a plant with intertwined roots is risky and often causes serious damage. Root disturbance is traumatic for plants, and unless there's a compelling reason, it's best avoided.

Instead, prune back individual stems and root each cutting in its own pot. The "mother" plant will produce new growth just below the pruning cuts, resulting in a shorter, more compact specimen. Meanwhile, you'll have multiple new plants propagated separately.

How to Prune and Propagate

• Cut each stem 1–2 inches below the lowest leaves.
• The lower portion will have aerial roots — insert these into the smallest pot that fits the cutting.
• Position the lowest leaves at or slightly above the pot rim.
• Use a potting mix similar to the original (well-draining, bark-based).

Aftercare Tips

Keep cuttings in bright, indirect light. Maintain consistent moisture — not soggy — until roots establish. The mother plant will rebound with fresh growth within weeks.
