of the fact that the members of the opuntia-family are domiciled all
over the american continent it is nearly impossible to give You an
universal cultivation-tip for all sorts.
are only a few warmth-needing sorts from the more or less subtropical
areas of South America that need temperatures of more than 10 degress C
and also a little water during the wintertime e.g. sorts of the genus
Brasiliopuntia, Consolea and Tacinga.
biggest part of my collection spends the wintertime dry at temperatures
of +/- 5 degrees C, whereas
some genus need prematurely (towards the beginning of March, when the
first periods of nice wheather take place) a lot of water for a rich
florescence e.g. the genus Corynopuntia, Cylindropuntia, Pterocactus and
like Maihueniopsis, Cumulopuntia (not all sorts) and Cylindropuntia
(also not all sorts) have to be stimulated to bloom by dryness and You
may give them water first if the sprouts are well developed – this can
endure until May....so You have to stay tough !!
plants of the genus Airompoa normally bloom very rich and more times a
year particularly at a higher age.
more or less hairy sorts of Austrocylindropuntia from the Peruan Andes
cannot endure any standing heat and have to stand absolutely airy and
spite of the “usual” cultivation there were even more flowers and
the plants were grown stronger.
the wintertime they necessarily need a bright plce and temperatures
lower than 10 degress C.
of matured, perennial seeds with the best results is possible during
wintertime at temperatures of 15 to 20 degress C.
called “hardy” Opuntias survive depending on the sort more or less
protected in stonegardens or in front of full-sunny housewalls. On not
suitable places the plants have to be protected against humidity in
autumn and winter (until March) by covering them with foil or glass.
have to be supplied with a full-component fertilizer in the early
springtime and in the summer (e.g. “Nitrophoska
permanent” or “Triabon”,
30 – 50 mg/m2).
sorts, e.g. the “real” Tephrocacti like “articulatus”, “weberi”,
“molinensis” or aoracanthus” like a more acidic soil, so I mingle
my substrate with some peat.
far also all other sorts liked my more acidic substrate, even it is
often recommended to mingle the substrate with some calc.
!! Mr Baudrexel from the “Oberländer Kakteenfreunde” discovered a
new source for the real
C. v. Wistinghausen
also can order Mr Wistinghausen’s extract in my Online-Shop (the
extract will of course be delivered with a prescription of use).
second watering is supplemeted with a concentrate of brown alga (depending
on the sort about 100 ml on 10 l of water).
I use a light concentrated fertilizer that is more or less poor of
mineralic substrates are in use You have to fertilize more often.
