aerial root care on Orchid
Quick answer
If your Orchid has aerial root care, the most likely cause is: Aerial orchid roots photosynthesize through chloroplast-containing velamen cells and absorb atmospheric moisture. When forced into pots, aerial roots often rot from lack of airflow, or desiccate from low humidity. Indoor environments below 40% relative humidity cause aerial root tips to desiccate within 72 hours.
Start here:
- 1. Do not trim healthy aerial roots—they photosynthesize and absorb moisture
- 2. For aerial roots remaining outside pot: mist daily or use humidity trays

How to reverse aerial root care on Orchid
- 1
Do not trim healthy aerial roots—they photosynthesize and absorb moisture
- 2
For aerial roots remaining outside pot: mist daily or use humidity trays
- 3
For repotting: position plant so newest aerial roots can emerge freely
- 4
Maintain 50-70% humidity for aerial root function; use humidifiers in dry climates

Keep aerial root care off this Orchid
Mount orchids on cork bark or use open baskets for epiphytic species. Clear pots allow aerial root observation without forcing them into media.
