Know before you buy
This cactus requires full sun, meaning at least 6 to 8 hours of direct sunlight daily. It is best placed in a south-facing window or an outdoor area with unobstructed exposure to thrive.
As a drought-tolerant succulent, it requires very little water. Allow the soil to dry out completely between waterings, and be sure to use a well-draining potting mix to prevent root rot.
The sap of the Mexican Fencepost Cactus can cause skin irritation and may be harmful if ingested. It is best to keep this plant in a location that is inaccessible to curious pets or small children.
It is hardy in USDA Zone 9, but you must protect it if temperatures drop below 25°F. If you live in a colder climate, it is best to keep it in a pot so you can move it indoors during the winter.
