This fun, interesting looking cactus features folds and ridges, which makes it look very... brain-like!
Water: A shot glass worth of water every 2-3 weeks is sufficient for this cactus. Avoid getting water within the ridges of this plant, as this will lead to rot. Water half as frequently in winter.
Light: Lots of bright, indirect sunlight.
Soil: Well draining cactus soil works best.
Humidity: brain cactus, like almost all cacti, are sensitive to excess humidity and moisture. Keep is a dry place.
Fertilizer: Fertilize in spring with a diluted solution of cactus fertilizer.
