Mine survive outside year around and they have never had any direct sunlight. I killed a few when I started out.
Now I just water them from below - Distilled only - and enjoy their beauty.
Sometimes, they look like they have died in the winter. What happens? They pull their energy out of the leaves and into the bulb-like roots as a survival technique. Keep them from drying out and they usually come back.
That's encouraging ^_^ How cold does it get where you are? We were concerned they wouldn't survive winter (or the height of summer for that matter).
It gets as low as 10 (45 F) at night during winter. As high as 35 (95 F) daytime in summer.
Oh that's similar to our ranges, yay there's hope XD Thanks :)
