Golden Rat Tail

Golden Rat Tail (Cleistocactus winteri) grows best when its natural cycle of strong light, freely draining soil and measured watering is respected. Give it bright direct sun to partial sun. Water it according to its seasonal needs: regularly in summer — more than most cacti tolerate. Plant it in fast-draining cactus mix with a little organic matter. A container with an unobstructed drainage hole is essential, because moisture lingering around cactus roots can quickly lead to rot. Keep its temperature needs in mind: 5–30°c. frost-tender. During active growth, check the compost before watering rather than following a rigid calendar, since heat, light and pot size all change how quickly it dries. Reduce watering during cool or dormant periods, keep the plant well ventilated, and wait until the growing medium is dry before watering again.

Stem cuttings root easily. Take material from healthy growth with a clean blade or tongs, then leave the cut surface in a dry, shaded place until it forms a firm callus. Set it into a dry, gritty medium and introduce water sparingly only after roots begin to develop. Young cacti are especially vulnerable to excess moisture. Use a small pot with excellent drainage, provide bright filtered light while roots establish, and move the new plant gradually into the light, temperature and watering conditions preferred by a mature Golden Rat Tail.
