E. phyllacanthus v
Generally solitary round cactus with whitish to cream coloured
spines and numerous wavy ribs. Older plants sometimes get corky near the
Flowers: Abundant white with pink midribs.
Remarks: Identifying the species of an
Echinofossulocactus is as difficult as identifying the genus is easy.
For the most part, they tend to look alike, and there are far more names
than there are species.
Cultivation: Easy to to
care and flower. No absolute schedule can be given
for watering as various factors (Soil mixture, containers,
drainage, temperature, size of plant) influence water use, so - as
a general rule - the soil should be thoroughly wetted at each watering
during the active growing season (spring and summer), water when the top
1,5- 2 cm of soil feels dry to the finger. Do not soak the soil during
the dormant period. Be careful, excessive watering can make root and/or
stem to rots. Make sure there is good air circulation between plants.
Good drainage is essential along good moisture retention properties and
adequate nutrients availability. Require bright sunlight to grow well.
Dormant plants do best at temperatures from 5-10°C (but will tolerate
-5° for short periods). The cooler temperatures develop sturdier plants
and encourage the formation of flower buds.
Pests: The narrow ribs, the wooly areoles, and the dense spines
are an ideal habitat for mealy bugs. Frequent inspection of the plants
will prevent them from spreading.
