 Cultivation: It is a summer
grower species that offers no cultivation
difficulties. Lobivia akersii has a fairly large
tap root, and should be kept in a deep pot with a very draining mineral
substrate. Water regularly in summer (but do not
overwater ) keep dry in winter. Feed with a high potassium fertilizer in
summer. Repot yearly until reaching about 100 mm in size, then
every two or three years will suffice. Repotting is best done at the end
of winter but can be done at other times. Do not water for a couple of
weeks after repotting to reduce risk of root rot via broken roots.
Repotting will increase size of stems. It
is quite cold tolerant if kept dry (hardy to -5° C). Outside
it need a bright exposure, full sun or half shade in summer,
inside it needs bright light, and some direct sun.
Propagation: Seed, grafting, cutting.
(seldom produces offsets)
