Different types of orchids can be found growing everywhere from deep shade to full sun. The most commonly available orchids we grow at home need bright indirect light at a minimum, and in some case direct sunlight. We photographed this Brassvola orchid is growing in dappled sunlight along a riverbank in Belize.
Above: To make sure your orchid has enough light in the winter, increase the amount of light by placing the plant in front of a mirror; a reflective surface will increase light.Also, they hate to have wet roots; choose a pot with good drainage and spread a layer of pebbles in the bottom of the pot.
