Corncob Cactus prefers dry environments. Providing extra humidity or misting your plant allows water to linger on leaves, which can create the perfect environment for harmful types of fungi.

Corncob Cactus is very sensitive to wet soil, so choose a potting soil that drains very well and doesn’t retain too much moisture. A good soil will have lots of perlite or vermiculite for drainage and some organic matter for nutrition. A few handfuls of perlite added to regular store-bought cactus soil will do the trick!

Corncob Cactus grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!

It’s common for Corncob Cactus to go dormant in the wintertime and you may notice their growth slow down. Waterings should be spaced out more during this time.

Corncob Cactus is native to Worldwide.

Corncob Cactus grows vertically and new growth will emerge from the top of the plant.
