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.
Monitor leaf color to determine if your orchid is receiving the proper amount of light. A plant receiving too little light will have dark green leaves, while one receiving too much light will present reddish-green leaves. Ideal light conditions will cause bright green leaves to appear. Be consistent in your care routine and patient with your orchid. Orchids are notoriously slow-growing and the rebloom may take place up to one year after the new growth appears.
