Monstera Deliciosa: root rot surgery
Quick answer
root rot surgery for Monstera Deliciosa: Root rot in Monstera deliciosa typically occurs from Pythium species or other water molds that thrive in waterlogged, anaerobic soil conditions. Research has identified coronamycin-producing Streptomyces endophytes in Monstera species that provide some natural antifungal resistance, but overwatering overwhelms these defenses. Infected roots turn black, mushy, and emit a foul odor as cortical tissue decays.
Start here:
- 1. Remove plant from pot and gently shake off soil to expose root system
- 2. Trim all black, mushy, or foul-smelling roots with sterile pruning shears—continue cutting until only white/cream firm tissue remains
