Following this question. Mine are in the garage (zone 6b) also since my little cuttings like yours didn't survive outside last year (maybe should have put pots/jars over them as suggested). I rooted them in this container with the lid on that retains moisture for them, so decided to leave them there for the winter & will bring them in if it's really cold (my cats can't get at them in the box when it's covered). Some have started to turn yellow, so I'm getting a little worried that I should have a lamp on them, or if it's normal?
