The Epiphyllum differs from other types of cacti in its soil requirements. Which substrate is suitable for a leaf cactus? This is how you put together the right soil for the Epiphyllum yourself.

Never use cactus soil as a substrate!
Even though the Epiphyllum is a species of cactus, its requirements differ from those of other cacti species. The leaf cactus does not thrive in cactus soil.
You can get special substrate for leaf cacti in stores. But you can also simply put the earth together yourself. It should be slightly sour and, above all, very loose.
For this you need normal soil for indoor plants, which you mix with sand or gravel. The mixing ratio should be two thirds earth and one third sand.
tips
You should never fertilize an epiphyllum with cactus fertilizer as it does not contain the right nutrients. Use a special leaf cactus fertilizer or liquid fertilizer for green plants with low nitrogen, the dosage of which is halved.
