I grew my Crepe Myrtle early spring and then knowing that winter was coming, I slowly put it inside to get it used to the indoor dark light and dry atmosphere. It's been two weeks now that I let it always inside and the lower leaf are starting to dry and die. I added an Humidifier yesterday hoping it could help. But for the light, I can't make any miracle as my window isn't really facing the sun anytime during the day. Just some low ambient light i'd say.
Is the lower leaf dying a normal behaviour of three during winter? Or is it slowly dying? What could I do to save it?
Side note: I live in Quebec Canada, so it's gonna be 6-7 month of cold temperature so I must keep it inside...
