Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive. In its natural environment this plant would receive dappled light.
Water: Allow the majority of the mix to dry out. Before watering, ensure the substrate isn’t compacted, if it is, aerate it with a few pokes of a skewer or blunt stick, pour water slowly over the top and allow the water to pass through the drainage holes.
Potting mix: A well draining mix composed of coco coir, perlite or vermiculite, orchid bark and worm castings; you could also add some horticultural charcoal to this epiphytic mix.
Fertilising: Feed your plant with a cactus fertiliser every other watering during the growing season or when you observe active growth. You can dilute fertiliser to half the recommended amount but never add more.
Temperature: 18-26°C, no lower than 12°C.
Humidity: Epiphyllum would prefer higher humidity but do well to adapt to average home humidity. You can increase humidity by placing the plant on a watered pebble tray or using a humidifier.
