How to save a plant from root rot

Recognize the problem

Typical symptoms: yellowed and limp leaves, soggy soil, sour/rotten smell, mushy stem base. Gently pull the root ball to confirm: healthy roots are pale and firm, rotten roots are dark and crumble to the touch.

Pull the plant out

Gently remove the plant from the pot. Discard all old substrate by shaking and rinsing the roots under lukewarm running water.

Cut the rotten roots

With sterilized shears (alcohol or diluted bleach), cut all dark, soft, smelly roots. Keep only white/cream root tissue.

Disinfect

Soak remaining roots in water + cinnamon powder for 30 minutes, or in 3% hydrogen peroxide diluted 1:4. Air-dry for 2 hours.

Repot and do not water

Repot in dry sterile substrate, in a clean pot with drainage. Do not water for 5–7 days: roots must heal without new pathogen risk.
