I would recommend a good quality potting mix with good drainage. Don't overwater during the winter months and keep it in as much sun as you can. If you have a few warmer days, over 65, maybe give it a little outside filtered sunlight but don't burn the leaves with too much sun... Next spring, put it in a bigger pot and gradually adjust it to 5-6 hours of sun outside and watch it grow.
Be patient on here, as many people come here like once a week or so. There are many who live in the north and will have much more detailed info for you. In the meantime, search the site and learn all you can.
