This is a question of individual choice and is better to ask “how the collector is taking care of her/his plants”. One must be honest with self when answering the question:”how often do you water”. Some people tend to water every time they look at the orchids (this is me) – this is too much, other are too busy and keep postponing the watering day after day until the orchids start to scream (Oh, they don’t? They just die?). For those who tend to water too much mounting orchids on a piece of wood or bark is the better choice. The mini baskets (plastic or wooden) are more universal setting – not only great for care, but also easier to arrange when orchids are on display.
If you ask me how I grow my orchids I will answer “the way you received them from me” I already have selected which setting is better for the plant under my conditions of regular watering. Changes from bark to pot and vise versa is best done right after the plant is done blooming.
