Orchids thrive in unusual circumstances in the wild. They adapted to cling to trees, rocks or make a home in leaf litter on the forest floor.
They receive water wherever it happens to fall - down the side of a tree, dripping from the leaves on a branch, sliding down the side of rocks.
But, unlike most plants, where they don't usually receive water in nature is from the dirt. The media they grow in is not earth, though some will bloom in very sandy soil.
Those natural conditions provide clues to the proper watering practices, which will vary somewhat depending on the species category in question. Epiphytes, for example, cling to trees, while saprophytes grow in leaf litter. But one thing is true of all orchids, overwatering is a much greater danger than underwatering.
