Cleistocactus strausii are slender columnar cacti known for the white fuzz that covers their trunks. They are native to high mountain regions of Bolivia and Argentina, where they enjoy a sunny desert environment often over 10,000 ft. Commonly known as the Silver Torch Cactus and prized for the silver coloration and unique red flowers.
Native to Bolivia and Argentina.
Cleistocactus strausii require plenty of full sun. Eight hours of direct sunlight a day is ideal but at a minimum these plants should be provided with at least five hours. If you are growing them indoors, a spot in a south facing window is ideal.
Cleistocactus strausii are extremely drought tolerant. During the grow season and when the soil is completely dry, water them thoroughly, fully saturating the soil. If you are unsure whether or not the soil is dry, wait a few days before watering. Excessive moisture can quickly lead to root rot.
These plants can be reliably propagated from stem cuttings. Use a clean, sharp blade to sever a segment of a stem or an entire branch. Place the cutting in a shaded area for a few days to allow the wound to callous over, then pot in a well-drained cactus mix. Fertilize: Cleistocactus strausii do not require fertilization, however a boost of nutrients during the growing season will help them thrive. Use a fertilizer formulated specifically for cacti and succulents, once a month, during spring and summer only.
