Banana Pseudostem Rot in Containers: Root-Bound Stress

Container Culture Causes Rot

Brown, moldy spots on the pseudostem of a potted banana signal root rot from restricted root space. The corm needs vast soil volume to manage water; pots keep it too wet.

Why Repotting Doesn't Fix It

Even large containers eventually bind banana roots. The corm rots because water cannot drain fast enough. No container size solves this long-term.

Only Real Fix

Plant in the ground in spring. If climate prohibits, accept the plant as a temporary ornamental and replace when it declines.
