The Moon Cactus is actually two cacti’s grafted together.
The top is a Golden Ball, while the lower green cactus is a Hylocereus cactus. Like many cacti, they prefer a drying period between watering’s. It is imperative that the cactus is not exposed to prolonged dampness and standing water or else it may develop root rot.
