General Information

Cultivation: The cactus prefers free draining soils, strong sunlight, but not high temperatures in fact it can withstand hard frosts down to -10°C. In its natural habitat it receives plenty of water during the summer, but almost none over the winter. In cultivation, watering too much in winter often leads to root rot.. Older cactuses, over 45 cm (18 in) tall, produce deep red, burgundy, flowers in late summer. The 6 cm (3 in) long cylindrical flowers protrude horizontally from the columns. In common with other cacti in the genus Cleistocactus, the flowers hardly open, with only the style and stamens protruding. Cultivated plants often flower freely

Propagation: From seed and pups

Hi
I have a 6 foot silver torch with 2 spines almost the same size . i need to re pot it but it is a bit wobbly and bendy how should i do it? i thought we might put rolled up newspaper around it stabilise it but im not sure if i should lay it on its side to take it out. Do you think that this would damage it and will it stand up with out bending when it is re potted ?
thanks.
