Vanilla Orchid is a high water content plant. It is with 92% water content in leaves, and 89% water content in vines.
Vanilla orchids should be watered regularly. Growing the Vanilla Orchid requires extra humidity and air circulation and this can often be difficult to achieve unless you are growing them in a greenhouse where you are able to control humidity levels in between 70%~80%.
You can also cover the roots with some wood chips, dead leaves or straw to keep moisture in Vanilla Orchid and minimise soil moisture loss. Please note, wood chips, dead leaves or straw must undergo disinfection before use.
Irrigating the Vanilla Orchid by micro-sprinkler with both irrigation and misting can increase the humidity, maintain soil moisture level at 25%~30% and pH level at 6.0~6.5.
