Default The secret to making Christmas Cactus bloom

My little cutting bloomed on a cold window sill while my big plant (30
years old) was being carefully lighted for only 8 hours a day, plunged into
absolute darkness as well as being carefully NOT watered, all without a
single bud in sight.

I dragged the big plant to the cellar -- and, believe me, that took some
work -- and put it on a cold windowsill for three weeks and BINGO! �Buds.


Mine bloom when not watered for a couple of months and allowed to
become really dry... I suppose cold would work too... many plants
attempt to reproduce when stressed. People tend to over water cacti
and succulents, but they can go a very long time without any water but
some don't handle cold very well so you need to define what you mean
by cold. No water is easy, no water means *none/zero*... but when you
say cold what temperature are you talking... it's real easy to
maintain no water but not so easy to maintain a constant temperature
except indoors, and I don't want to live at say 50F.
