Don't assume anything. You know what they say about people who assume?

I think I'm learning.

Without an actual description of the plant and its flowers, it could be
any
of hundreds of night blooming cactus species in several genera, ranging
from
epiphytes, vines, columnar species and even tuberous rooted geophytes.

Quite correct. However, that's not the point here. The above epiphytes have
general, common requirements as do the terrestrials. If gwayner just wants
help in growing the plant to blooming, that's all he needs to know. You can
call the plant an SOB for all the plant cares about names. There's no reason
on earth a person can't grow a plant without knowing its "real" name. The
general rules I listed earlier will help him grow just about any of the
species fitting the description of night blooming cereus.

As I have said before, there is no such plant as "Cereusly peruvianaus".
The
plant passing under that name in the horticultural trade is something
else.

Again, quite correct. Again, irrelevent.

I'm assuming you're talking about a semi-epiphyte, the kind with flat,
triangular, or even round stems. They may or may not have visible spines
but
all will grow arial roots along their stems especially when stressed for
water. This is the most common kind I've come across referred to as
night
blooming cereus. They may include Hylocereus, Selenocereus, Epiphyllums,
etc. Regardless of the name, they all want a porous, well-drained, but
moisture retentive mix to grow in. We grow the epiphyllums in a mix of
spongerock and coconut chips with a healthy handful of coconut dust
thrown
in each 12" basket. The uprights or rampant growers we pot in 4-5 gal
containers of similiar mix and try to keep them from rooting through the
woven ground cloth into the ground. Pot-bound is not a problem. When
their
happy, your main job will be to constrain their growth. We had a
Hylocereus
we struggled to keep at 6-8'. We treat them similiar to our orchids by
fertilizing them 1/2 strength every week with bloom builder substituted
in
early spring. With strong light ~50% shade, ours bloom over several
weeks
with as many as 20 blooms open at a time. There's frequently a rebloom
in
late summer.
Now if you are talking about a Cereus peruvianus or similiar relative,
potting in a well-drained mix is still a requirment. Run a large knife
around the inside of the pot right up against the pot to remove the
roots
from clinging to the pot. Disturb the roots if they're a tight mass so
there
are free ends to grow out into the new mix and repot in the next larger
pot.
I don't know many who refer to this as the night blooming cereus,
although
the flower is large, opening at night at lasting several days.
I do believe, however, that a person can grow a plant well by its common
name without knowing the technical one. People have done it for many
years,
and without ridicule.

I have a night blooming Cereus that bloomed about 20 years ago and
never
since. What do I have to do to get it to bloom again.
