overwintering black and blue salvia
I have seen multiple posts re: this topic -- but still have a few questions -- any guidance would be greatly appreciated!
1) KEEPING IT IN THE HOUSE: If I bring my potted b&b salvia into the house -- should I leave it in a sunny room? Is it okay for it to be in a heated house all winter? Does it need a special grow light?
2) KEEPING IT IN THE GARAGE/BASEMENT: Does it require a dormancy period -- should I put it in the dark/cold windowless basement - (or unheated garage) and not water it at all?
3) Either way -- does it need to be watered (lightly) throughout the winter?
4) Do I need to cut down the green stems or can I just leave it "as is?"
Thanks in advance!
