Hoya root rot

Thick leaves can hide root loss until they wrinkle or yellow. Persistent wilt in wet medium or a soft vine base justifies unpotting; root color alone does not establish rot.

Save roots and nodes that remain firm

Remove collapsed roots with clean scissors and discard decomposed medium. Use a clean pot that fits the surviving roots and a fresh, airy mix. Thin-leaved hoyas need more consistent moisture than thick-leaved types. Follow the root rot cleanup steps for tools and containers.

If the base is failing, take a firm vine cutting with nodes beyond the damage and root it in lightly moist propagation medium. Keep it warm in indirect light. A detached leaf without a stem node may root without making a new vine.
