Cultivation and Propagation: Echinopsis spachiana is a a much decorative frost hardy cactus easily found in cultivation and grows virtually anywhere. It is a summer grower species that offers no cultivation difficulties. It can be overwintered outdoors if sheltered from rain and severe frosts.
Soil: Use a very a particularly draining substratum, as it is very sensitive to rottenness when in presence of humidity and low temperatures and let the soil dry out between waterings, since it's natural habitat is in volcanic soil, it has adapted to more acidic conditions.
Repotting: Repot in the spring, when their roots become cramped. Generally, they should be repotted every other year in order to provide fresh soil. After repotting, do not water for a week or more. Needs a large pot to accommodate a large root system.
Water: In summer, during the vegetative period, it must be regularly watered, but allowing the substratum to completely dry up before irrigating again (but do not overwater). In winter, it’s to be kept dry. Preferable not to water on overcast days, humid days or cold winter days.
Hardiness: It is a quite frost resistant cactus, hardy to - 10° C (or less if very dry). However in cultivation it is better not to expose it to temperatures lower than -0° C, even if in an aerated and protected location, in order to avoid the formation of anti-aesthetic spots on the epidermis. In presence of high atmospheric humidity avoid any frost as it is particularly sensitive to root rot.
Exposure: Outside full sun or afternoon shade, inside needs bright light, and some direct sun, but, as a former mountain dweller, does not care for extremely high temperatures in summer.
Use: It is suitable for small “desert” gardens, in association with other xerophytes. Where the open air cultivation is not possible due to the climate, it is to be cultivated in pot in order to shelter it in winter.
Grafting stock: Trichocereus spachianus is often used as a rather thick stock.
Propagation: By seeds and by cuttings, provided left drying up well, in summer.

Rather nervous when we planted golden torch cactus last June as the green exterior browned immediately and looked as if it burned, making us more uncomfortable. This week, 6/11/09, multiple blossoms opened for a day, -overwhelming in beauty. The flower barely lasted a day. Now what to do with the dead flowers on top of the torch?? leave them, cut them off. there are apparently more flowers developing. Where to learn more about this cactus. Thanks

The next most common botanical name that is referred to as is: Trichocereus spachianus. In fact as of at least today (5/25/2017), it may have been switched back into the Trichocereus genus in the latest classifications. This plant is able to handle full sun, no shade, with a little extra water in the hotter summer months, the other ones i see in other landscapes that get no extra water usually have a burnt side. Blooms at night and closes when the strong sunlight hits it.

This cactus is a beautiful plant and fairly easy to grow. It usually blooms from mid April to early July. Sometimes it will bloom again in early to mid fall. The flowers are large(8"-10" across) and strongly scented. They open in the evening and last until noon the next day. During cool or cloudy weather, they may stay open for 2-3 days.
