Reviving a Large Ming Aralia: Hard Pruning and Repotting

Diagnosis: Overpotted and Overwatered

Your 6-foot Ming Aralia (Polyscias fruticosa) in a 24-inch pot is suffering from chronic overwatering due to excessive pot size. The large soil volume stays wet too long, causing root rot. Weekly watering in spring/summer is too frequent for this pot size.

Rescue Plan: Drastic but Necessary

1. Repot into a 16-inch max diameter pot (lightweight, with drainage). Use a 20-inch clear saucer.
2. Soil mix: 2 parts potting soil + 1 part perlite for fast drainage.
3. Prune hard: Cut back to ~3 feet (half height). This stimulates bushy regrowth.
4. Watering protocol: Water thoroughly, then empty saucer at 2 hours (use turkey baster if too heavy). Wait until soil is very dry before next watering.
5. Light: East or west window—bright indirect.

Why This Works

Smaller pot = faster dry-down = healthy roots. Pruning reduces top growth the compromised roots must support. Ming Aralias respond well to hard pruning.

Root Pruning Alternative

If you can't repot now, root-prune: remove plant, shave 1–1.5 inches off the root ball perimeter with a saw/knife, repot in same pot with fresh soil around the edges, and prune top growth proportionally.
