Philodendron: stem rot surgery
Quick answer
stem rot surgery for Philodendron: Stem rot in Philodendron results from bacterial (Erwinia) or fungal infection entering through wounds or prolonged stem wetness from overwatering, high humidity without airflow, or poor drainage. Unlike root rot, healthy roots may persist while stem tissue decays.

- 2. Sterilize cutting tools; remove all rotted tissue until only firm, healthy stem remains
