Epiphyllums are popular wherever they can be found. I would suggest, humbly, that it is because of the amazing flowers.
Cuttings from the plants are easily rooted. From spring until fall, the plants can grow outdoors in hanging baskets attached to tree branches, providing filtered light. The baskets can be lined with coconut fiber and filled with cactus soil, both to ensure excellent drainage….
When temperatures drop, baskets need to be moved to a protected location that has bright natural light.
I don’t recommend that you click through to the article that this lovely photo comes from. I have safely excerpted as much as you need to know about epi’s. Whatever you do, don’t read the part about how they fertilize. Noooo!!!!! Oh, the humanity.
We use a well balanced slow-release cactus fertilizer, and add extra fish bone meal to encourage blooming. If you want to use a liquid fertilizer, only use a low-strength organic product for strong healthy growth.
We water them once a week, and plant them in our jungle cactus/orchid mix soil which is very similar to a cactus soil, but has chunks of coconut husk chips in it, and extra slow-release organic fertilizers.
Definitely use a hanging basket, coir-lined if possible. And don’t forget to share your cuttings with your friends.
