Cultivation:
Trichocereus hybrids are very easy to grow and
cold tolerant,as
low as -5/-12°C (or less depending on clone). They need a fertile, well
drained soil mix. Water the plants well and allow them to dry before
watering again. This cultivars seem to do better with a little more
water than most cacti. In fact, their cultivation requirements are
really more like 'normal' plants than most other cacti. During the
growing season fertilize them monthly with a balanced fertilizer
Sun Exposure: Outside
full sun, but during hot summers the cactus are subject to sun
burning, so grow them in light shade. Inside they need bright light, and
some direct sun. During winter months, put them in a cool luminous place
and encourage them to enter winter dormancy by withholding water and
fertiliser over the winter, as they will etiolate, or become thin, due
to lower levels of light. They are susceptible to fungal diseases if
overwatered, but are not nearly as sensitive as many other cacti,
especially in warm weather. They tend characteristically towards black
rotted spots unless watering is moderate and only in hot weather. If
kept damp through cold periods, they will invariably suffer.
This plants produces large amounts of growth each year if kept well fed
and watered throughout the warmest months, particularly if they have
been acclimatised to accept full sun. Once these cactus are established
they can easily produce 10cm (or more) of growth every year.
