Philodendron: water propagation rot
Quick answer
water propagation rot for Philodendron: Water propagation causes bacterial soft rot in philodendron cuttings when stagnant water promotes anaerobic bacterial growth. The sugary sap released from cut surfaces feeds bacteria like Erwinia chrysanthemi, causing mushy stem collapse before roots develop.
Start here:
- 1. Use clear container to monitor root development and water clarity
- 2. Change water completely every 3-4 days - never top off existing water

- 2
Change water completely every 3-4 days - never top off existing water
- 3
Rinse cutting and container with fresh water during each change
