Distribution |
north - Mexico
USA - southwest - Texas
warm arid regions |
Growth period |
full sunny and a warm location, very sensitive to too much moisture, keep the root neck dry
moderate watering, only from below and not in the woolly crown
from mid of July to mid of August is a summer rest period prefered
in this time keep the plants complete dry, this furthers the flower formation
the main growth period and flowering time is in fall, then a little more watering |
Winter period |
completely dry and cool in 4–8°C (39.2 to 46.4°F) |
Substrat |
very porous, pure mineral, sandy-loam
with the addition of limestone gravel, pumice, granite crumb, expanded shale, quartz and pebble tiles
addition of gypsum fertilizer in small amounts is good |
