Description

Cleistocactus smaragdiflorus is a multi-stemmed cactus densely branched at the base and up to 6.6 feet (2 m) tall. Stems are usually erect, up to 3 inches (7.5 cm) in diameter with 12 to 16 ribs with closely set areoles and spines. Flowers are tubular, red to pinkish, up to 4 inches (10 cm) inches long and up to 0.5 inch (1.2 cm) in diameter.

How to Grow and Care

Choose a location that gets full sun and has well-draining soil. Water Cleistocactus during the spring and summer when the top inch (2.5 cm) of soil dries out. During the fall, reduce watering to every 5 weeks if the ground dries out. In winter, keep your cactus dry or the moist ground combined with the cool temperatures and dormancy may cause the roots to rot. Fertilize with a low-nitrogen fertilizer during the active growth period. A slow-release fertilizer applied in the spring will be sufficient for the whole year.

It is possible to propagate by cutting a small branch from a Cleistocactus and rooting it, but this inevitably leaves a disfiguring scar near the base of the main stem. If an offset is removed to be used in propagation, remember to let it dry for a week or so, letting the wound heal. Rooting usually occurs within 3 to 8 weeks. It is therefore best to raise Cleistocactus from seed. Be sure to get the seeds from a reputable source.
