The kooky Spiral Cactus

Pests and Diseases
Spiraled Cereus is susceptible to mealybugs and scale. If detected, apply an insecticidal soap to the plant according to the directions on the label.

Like most cacti, Cereus are fairly low-maintenance and very hardy. Make sure they receive sufficient water during the summer without becoming waterlogged, and fertilize for best results. If the roots have become black or mushy, the cactus may be suffering from root rot. Cut away the affected parts and replant. Most gardeners who grow cacti should be able to cultivate this variety without a problem.
