Cleistocactus icosagonus

 

Cactus 'Icosagonus'

Cleistocactus In the genus Cleistocactus many of the features of this genus are small, but profuse. The stems are usually a few cms or so in diameter, but branch readily at the base to form obvious clumps. The spines generally are small and flexible, but usually very numerous even to the point of obscuring the stems. This trait is also true with the flowers. Many species have flowers that resemble little tubes of lipstick or firecrackers appearing fairly closed. Stems may be full of flowers with many buds developing. In the right conditions a plant can even have flowers open every day of the year. This genus is widespread throughout much of South America and can be found growing in large shrubby clumps mixed in with other vegetation. Several species are extremely popular in cultivation and are among the most common of cactus in nurseries worldwide; the two most popular of all being C. strausii and C. winteri.. This Cactus prefers full sunny positions, but not extremely high temperatures. While in its native environment it is noted to survive down to -10 degrees Celsius, cultivated specimens are best kept frost free with a minimum winter temperature of 10 degrees Celsius. It needs good drainage and should be potted in a sand , gravel and soil/compost based mix.

Planting young plants

From Early Spring TO Early Spring

Cleistocactus typically don't like direct afternoon sunlight and should be in partial shade through the hottest hours. They can take direct sunlight in the morning and afternoons. A rich, fast-draining cactus mix is ideal. To plant, do this preferably during the warm season. To repot a cacti, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
