Cereus aurora Plant Care
Cereus aurora Rydb.
Updated · Sources · How we source care data
Cereus aurora is a columnar cactus in the genus Cereus (family Cactaceae), first described by the botanist Per Axel Rydberg in 1906. It is a rarely recorded name and little has been documented about it in the wild, so it is best understood through its genus: Cereus are tall, ribbed, candle-like cacti from South America and the Caribbean, many of which open large white flowers at night that close again by the following morning. In cultivation, plants sold under this name need the same care as other Cereus: full sun, a sandy, fast-draining cactus mix, and deep but infrequent watering, letting the soil dry out completely between drinks and keeping it almost dry in winter.

How Do You Repot a Cereus aurora?
Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Cereus aurora?
Cereus aurora can be propagated through stem cuttings, grafting. Similar propagation techniques also apply to seven stars cactus plant care, which shares the same genus.
