This good looking columnar cactus will grow about 5 to 7 inches a year. They are cold intolerant. Make sure they are not exposed to freezing temperatures. They need a well-drained soil mix. Water regularly in summer but allow to dry fully before watering again. During the winter months they should be rather kept dry. Since they are rapid growers, they need plenty of space for their roots. Repotting should be done every other year, or when the plant has outgrown its pot. Sun Exposure: Light shade when young, full sun later.
