Fraileas are relatively easy to grow cacti. They need a porous, fast draining soil and enjoy quite frequent waterings during the growing season. When temperature drops, keep dry and at positive Celsius temperatures.
This particular specimen was collected in 1998 by Bruno Knutti and Christian Hefti in a locality North-West of Mario Rubio, on Ruta 31, Salto Uruguay. I grew it hard, outdoors, with lots of sun and hot temperatures during summer, and it could probably tolerate some frost during the rest season. However, I keep it at around 10 degrees Celsius, completely dry.
