Rebutia vulpina is easy to grow and free flowering. Nevertheless.
Growth rate: It is a relatively rapidly growing species that will make large clumps given the best conditions.
Watering: Needs moderate to copious waterings in the summer (it is more demanding than other cactus), but do not overwater, keep dry in winter at a minimum temperature of 0°C.
Hardiness: It is quite frost resistant if kept dry.
Exposition: The plant tolerates bright situations which encourages flowering and heavy spine production but is likely to suffer from sun scorch or stunted growth if over exposed to direct sunlight during the hottest part of the day in summer. It grows well with filtered sunlight or afternoon shade.
