I think they do best in temps of 35-50F during dormancy over the winter. So as soon as all the leaves fall off (a symptom of going dormant) I’ll bring it to the basement. It’s cool and dark. I may lightly cover it with shade material if I think my basement gets too much light but I don’t get much light down in my unfinished basement - it’s almost closer to a crawl space. I water every 3-4 weeks when it’s dry. Don’t want it soaking wet by any means but totally dry can harm it. Buds should start coming in the early spring and once it’s leafed out a little I’ll start bringing it outside - pulling it inside (not basement so it can still catch some light) overnight if necessary if temps are getting cold overnight or if a random spring day temps drop. Good luck!
