What potting soil to use with a night blooming cereus?
Since epiphyllums grow in the crotch of trees, they like a soil miix with a lot of leafmold in it. Do not use an epiphytic orchid soil or cactus sand. You can make you own with a good potting soil and a lot of clean, well aged compost, and maybe 10% sand for good drainage, but not too much, as epiphytes’ roots should never completely dry out. I’ve always had several growing, including one given to me by a woman who had it for 25 years without it ever blooming. I’ve had it for twenty with not better luck, but a friend has one he’s shaped into a tree and he gets 25-40 flowers every year. The night blooming cereus is the jungle variety from which the hybrid epiphyllums were developed.
