crown rot prevention on Phalaenopsis Orchid
Quick answer
If your Phalaenopsis Orchid has crown rot prevention, the most likely cause is: Phalaenopsis crown rot occurs when water pools at the crown (where leaves meet the stem), creating anaerobic conditions that promote bacterial and fungal growth. The crown is the growth center for new leaves and roots - rot here spreads rapidly and can kill the entire growing tip. Crown rot is caused by top-watering that saturates the crown, misting directly over the plant, or positioning the orchid so that water collects in the leaf axils.
Start here:
- 1. If crown rot is detected early (soft brown/black center visible at growth point): remove orchid from pot immediately
- 2. Excise all soft, brown, or black tissue at the crown with sterilized scalpel or sharp scissors, cutting into healthy tissue until you see white/green
