They need filtered light and watered at least once a day in Florida during summer time, they can go couple days with out watering but dont thrive as well. We do feed them liquid orchid fertilizer every 2-3 weeks too.
We have about 50 orchids, we rotate them to front once they start blooming, seems we always have a few blooming but we do spray they with orchid bloom fertilizer about every 3 weeks, keeps them healthy and blooming often.
