Cultivation: It's very difficult to find high quality plants of this species in cultivation, S. rauschii loves a very permeable, coarse mineral soil. It must strictly be kept dry throughout  the winter quiescent period since it is very sensitive to any moisture excesses, To prevent rottenness it is also advisable to surround its root neck by very rough sand or grit.  This helps a fast water drainage and an appropriate air circulation.
For its sensitive roots this species is frequently grafted to avoid root problems. Plants grafted on Opuntia compressa are easy to grow and quite frost hardy -5 (-10)° C
Watering Needs: Water moderately in the growing season, keep dry during  the winter rest
Frost Tolerance: 
Overwinter  in a cool place (at 0/10°C). This is important for the flowers as well as for plants' health. Without this cool winter period they normally won't get any buds.
Propagation: Seed, cutting, grafting

Sun Exposure: Needs a full sun exposure (light shadow may be useful in the hottest summer days)

 

Propagation: Seed, cutting, grafting.
