Root Rot Propagation Rot on pothos
What's Happening
Pothos cuttings in water propagation develop rot when water becomes stagnant and oxygen-depleted after 2+ weeks without changing. Anaerobic bacterial colonies proliferate, attacking water-adapted aerenchyma roots that lack structural defenses against pathogens.
How to Fix It
- 1
Change propagation water every 5-7 days without exception
- 2
Use filtered or distilled water—chlorine in tap water stresses cut tissue
- 3
Add 1-2 drops of 3% hydrogen peroxide per cup of water to oxygenate and inhibit bacteria
- 4
Rinse roots gently under lukewarm water at each water change to remove biofilm
- 5
If rot detected: Trim affected roots with sterile scissors, sterilize cutting in diluted H2O2 (1:4), restart in fresh water
- 6
Transition to soil when roots reach 2-3 inches—avoid prolonged water residence
How to Prevent It
Never let water stagnate beyond 7 days; use clear containers to monitor root health; maintain 65-75°F ambient temperature; provide bright indirect light to support healthy root metabolism; sterilize containers between uses.
