Quick answer
If your Phalaenopsis Orchid has air roots green, the most likely cause is: Phalaenopsis aerial roots turning green indicates active hydration - the velamen layer has absorbed water and is conducting photosynthesis. Green aerial roots are healthy and indicate the plant is well-watered. Unlike terrestrial plant roots, orchid aerial roots contain chlorophyll and perform photosynthesis when exposed to light, contributing up to 20% of the plant's total carbon fixation.
Start here:
- 1. Green aerial roots are healthy and indicate the plant is adequately hydrated
- 2. When aerial roots are bright green, the plant has sufficient water - postpone watering
