I read many contradicting things on the overwintering issue. I have some questions.
Is forcing desert cacti in winter dormancy imperative? I read that it is, as this prevents etiolation.
But the temperatures that are to kept the cacti when in dormancy are rare happening where I live. Yes, sometimes we could have winter nights from 41 to 50 F (which is 5-10 C), but those will not be many in a winter! So I can't provide my cacti the right low temperatures I read are needed for them to stay dormant until spring.
As for a dark and unheated room, I can provide that. I can crack a window and turn the heater off. But the light will be limited, no sunlight there. My other option is to get them outside either on the north or the south balcony. If I put them at the south balcony, the temperature will get hotter as the sun hits it. At the north balcony, there will be no sunshine, just the colder temperatures, cooler days and colder nights. It is also windy, so much more cooler than the south one.
I have made sure they are kept dry, but still I am at a loss what to do and how to proceed.
I read most of the members in cold areas are getting their cacti inside to overwinter, and I have to get them outside to prevent etiolation?
