pull it out of the pot see if its got root rot. if you cant figure it out find the best branch and cut it off and let it sit there in a dim spot dry for the rest of winter mby some sand no water till spring. you wont kill it by pulling it out and letting it sit bare root till spring thats what i would do right off the bat. even if it is trying to grow right now that should kick it into dormancy. also cold put it in unheated garage or something.
