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.
Create the right temperature for your orchid. Most orchids originate from a tropical climate, meaning good air, plenty of light, and 12-hour days (365 days a year). The temperature (depending on the species of orchid) should range between 65 to 75 degrees Fahrenheit (18.3 to 23.8 degrees Celsius). Dropping the temperature of the orchidâs environment at night by about 10 degrees will promote new buds, especially during the fall and winter.
