I am on the 4th floor. How much sun can the epiphyllium take on my balcony. My balcony gets direct sun from 9-1pm.
Alameda County California
In general, Epiphyllum do best in filtered sunlight. They seem to like a few hours of full morning sun, but never full midday sun. If possible, keep them in a shady spot outdoors in the summer. See the link from Oregon for more information and care
