Cultivation:  The crests are frequently grafted onto a  Myrtillocactus geometrizans  trunk, but are easily grown on their own roots. Indicated for full sun exposure.  Water regularly from March to October. Rot prone in winter, it needs good drainage,  It should be kept in a cool place during winter rest (it can briefly tolerate temp. as low as -7°C). Stems may possibly become purple and limp in winter, but revitalize in early spring. Any normal shoots should be removed to promote the growth of the crest.
Propagation:
Grafting,  It can also be increased by cuttings, which will take root in a minimum temperature of 20° C. Cuttings of healthy shoots can be taken in the spring and summer, Cut the stem with a sharp, sterile knife, leave the cutting in a warm, dry place for a week or weeks (depending on how thick the cutting is) until a callus forms over the wound. Once the callus forms, the cutting may be inserted in a container filled with firmed cactus potting mix topped with a surface layer of coarse grit. They should be placed in the coarse grit only; this prevents the cut end from becoming too wet and allows the roots to penetrate the rich compost underneath. The cuttings should root in 2 to 6 weeks.
