Austrocactus native to Patagonia South America is rather unknown and not widespread in cultivation. However, it has something to seduce with its incredible blooms. But they are also resistant to cold (-11°c without problem for me).  Elisabeth and Norbert Sarnes, a German couple, are known for their immense work on this genus and the dissemination of its seeds. Thanks to their book and some advice obtained from Elisabeth, I can give you the following recommendations in order to cultivate this genre as well as possible.

As Pediocactus, their growth period starts earlier than other types of cacti and they rest during the hot summer period. They appreciate early watering and very good ventilation. I grow them under a simple rain cover where the air can circulate freely. This is how I treat my plants:

• Very mineral substrate (90%)

• Water at the end of February/beginning of March as soon as the temperatures reach >10°c during the day

• Stop watering when daytime temperatures exceed 30°C and nighttime temperatures do not fall below 20°C (generally corresponds to the summer period)

• Fertilize heavily in the spring for the production of flower buds

• Water lightly from September to mid-October.
