Schefflera arboricola Decline After Overpotting: Root Rot and Recovery

A 4-foot Schefflera arboricola (braided trunk) was repotted from 10" to 14" pot with rocks for drainage. Within weeks, leaves and branches dropped; one stem turned black and lost 90% foliage.

Cause

Unnecessary repotting into too-large pot. Excess soil retains water, displacing oxygen, causing root rot. Rocks at bottom worsen drainage. Black stems/leaves confirm rot.

Rescue Steps

1. Remove all added soil; preserve original rootball and healthy roots.
2. Cut off black, mushy roots and stems.
3. Repot into smallest pot that fits (original 10" or smaller).
4. Provide bright indirect light, warm temps, water only when top quarter of soil dry.

Recovery is slow and plant may never fully regain former appearance.
