A Monkey Tail Cactus is a great plant for beginners. It has long, white, soft, hairlike spines and gets large bright red flowers. It looks best in hanging baskets. It’s hard to believe, but a Monkey Tail Cactus can survive temperatures below freezing. Water when the soil has totally dries out. The warmer the air the more frequently you’ll need to water. When it is cloudy and cold, it will take the soil longer to dry out. Keep the soil even drier during late fall and winter when a Monkey Cactus needs to “rest” for a few months in a cool area. This dormant period is necessary for it to bloom well.
