How to Grow and Care

Like most cacti, Cereus are fairly low-maintenance and hardy. Make sure they receive enough water without becoming waterlogged, especially during the summer, and fertilize them for best results. If the roots have become black or overly soft, the cactus could be experiencing root rot – cut away the affected parts and replant. Like all cacti, give them lots of direct sunlight, especially during the summer. Well-drained soil is best, and most Cereus perform well in a soil that contains some organic material… – See more at: How to Grow and Care for Cereus.


The native origin has never been resolved, but is likely from West Indies, Caribbean Basin, Southern Mexico through Belize, Guatemala, El Salvador and Costa Rica.
