Not easy, because of the mountain environment in which the plants live,
they need as much direct sun light as possible to encourage the heaviest
spines an wool formation, plants in shaded positions grows etiolated and
fail to produce the typical hairy covering. They need to be kept in a cool place during
the winter rest (at 0
