Cultivation: It is a species
of easy culture, recommended for any collection, it doesn't require any
special treatment. Water regularly in summer, but do
not overwater (Rot prone)
Use pot with good drainage and a very porous potting media,
keep dry in winter.
Feed with a high potassium
fertilizer in summer.
It is quite frost resistant if kept dry, hardy as low as -5° C (some
reports give it hardy to -5°C)
Sun Exposure: High levels of light are needed to
flower and for good spine development.
Can be sunburned if moved
from shade/greenhouse into full sun too quickly. During the spring it
may be able to take full sun until the heat arrives at the end of
spring. In an area that has hot afternoon sun, it may be able to take
full morning sun, but requires afternoon shade or afternoon light shade.
If grown correctly, it will reward the grower with generous
displays of small pink flowers followed by red berries.
Clustering in cultivation and easily flowered.
For best results, use a shallow pot, and only use the smallest
diameter pot that will accommodate the plant. Sensitive to red
spider mite. Overhead watering is helpful in controlling mites.
Propagation: Division, wait until the offsets that appear at the
base of old clustered specimens are 1/3 the size of the parent and then
detach and plant.
