Echinocereus


Echinocereus is natively from Mexico and southern USA, it is a small globose or cylindrically stemmed genus that belongs to the cacti (Cactaceae) family. This genus is presented by 120 species and now incorporates many of the species previously in Lobivia and Trichocereus. The stems have conspicuous areoles on tubercles or on the ribs themselves and are usually many-ribbed. They blossom from spring to midsummer, the spines are large if compare with the plant size, they can be curved or hooked, the flower scan be of different shades of cream, purple, pink, orange and red. The blooms are tubular, long, and often spectacular. Echinocereus means "hedgehog cactus," and it needs a lot of care.


Top Tip

Grow Echinocereus
plants in a shallow
soil—without organic
matter—that
is fast draining and
in full sun. The soil
should be allowed
to dry out between
summer waterings.

Cultivation


Echinocereus needs light, gritty, very well-drained soil and a full sun position. Needs to be occasionally watered when it is young or during the periods when it is too dry, otherwise it survives on natural rainfall. Propagates from seed, but from seed it develops too slow, so its easier to propagate by offsets that are often numerous. Cacti in this genus with dense, comblike spines, such as Echinocereus reichenbachii, arc fairly slow-growing and best raised from seeds sown at 70°F (21°C). Those with open spination. such as E. cinerascens and E. pentalophus (syn. E. procumbens), tend to be faster growing and make fine clumps: these cacti can also be increased from columnar stem cuttings. Sever a stem near its base and trim to 2-4in (5-10 cm). Leave for 1-2 weeks to callus, then treat as standard cuttings. They may take 1-3 months to root and produce a good plant in 1-2 years. It is possible to take cuttings from the slower-growing species, but they may take up to two years to root and are very prone to rot. Most species tolerate temperatures to 45°F (7°C) if dry, but prolonged cold marks plants badly.
