Monstera root rot

A large monstera can have healthy roots at the pot edge while the center is wet and decomposed. Persistent wilt, yellowing, and soft roots are stronger evidence than how many days the surface stays damp.

Remove rot and fit the pot

Ease the plant out, remove collapsed roots with clean tools, and discard broken-down mix. Retain firm roots even if their color differs. Use fresh mix with good air space and a clean pot that fits the roots left after trimming.

Support the plant while roots recover

Replant at the same depth, stabilize the stem, and moisten the root zone evenly without leaving runoff. Water again after the upper mix dries. Aerial roots can help anchor the plant but do not compensate for a rotten root ball. If the stem base is failing, a firm stem cutting must include a node.
