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 the 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 them. Most gardeners interested in cacti should cultivate these without much problem.
It may become necessary to repot your Cereus if it outgrows its container. If so, make sure the soil is dry and then remove the pot. Knock away old soil, prune away any rotted or dead roots, then replace it in a new pot and backfill it with fresh soil. Ensure not to overwater cacti planted in new pots, as this can lead to root rot. It should be left dry for about a week and then watered lightly.
These cacti propagate quite easily from cuttings. Simply sever a branch and replant in moist, well-drained soil.
