Sunlight
As a sun-loving plant, Corncob Cactus would benefit from 4-8 hours of direct sunlight exposure daily. Put this Cactus near a south- or west-facing window to create a close to its natural habitat environment.
Soil
Just like most cacti, Corncob Euphorbia feels best in well-draining, nutrient-poor soil. Plant this Cactus in a succulent-special potting mix with 6-8 pH. Alternatively, mix some sand and perlite with a regular soil mix to improve drainage.
Propagation
Stem cutting is the easiest way to propagate Indian Corn Cob, as this greenie grows in a bushy manner. Cut the stem at the base with a sterile blade and leave the cutting for a few days to let the callus emerge. Place the new plant in a well-draining potting mix and keep the ground consistently moist to let the cutting enroot.

Fun fact
The plant’s common name Corn Cob Cactus hasn’t originated out of nowhere. The Cactus grows in a bushy manner and produces cylindrical stems with pinkish tips. Such a form and color combination closely resembles corn cobs.
