Gymnocalycium mihanovichii is a species of cactus from South America. The most popular cultivars are varied mutants which completely lack chlorophyll, exposing the red, orange, or yellow pigmentation. These mutant strains are often grafted onto the hylocereus cactus, and the combined plant is called a "Moon Cactus".Moon cacti are commonly grown as houseplants and are also known as Ruby Ball, Red Cap, Red Hibotan, or Hibotan cacti.
HOW TO TAKE CARE:
The moon cactus plant requires bright indirect sunlight.Water deeply and then allow the soil to completely dry to the base of the pot before reapplying moisture. Suspend watering in the winter months and repot in spring to reintroduce nutrient dense soil. The moon cactus prefers to have a crowded home, which means you can repot in the same pot for several years.
