Overwintering Rosemary?

I have a year old rosemary plant. This plant was a cutting from my school and it spent last winter in the greenhouse at my school, then spent a couple months in it's little container in my sister's room in front of the window (to keep it away from the cats). When it got warm enough, I transplanted it in a hanging basket and hung it out on a hook in the garden. The soil appears to be largely clay and silt based, and stays fairly dry if I don't involve myself with the watering and leave it to the rain. When it was smaller, I brought it under the eave in front of the house if it was going to pour and I hung it in front of the kitchen window if it would get too cold. Now I pretty much leave it outside all the time to stick out the weather. The plant is about six inches high and wide now. I checked on it today. No weeds or anything in its pot and the plant looked healthy, as per usual. However, a few of the needles were brown so I pinched them off. This plant has not been harvested from yet as it is still too small. I live in southeastern Connecticut (not sure what our zone is) The temperature has dipped down to 35 degrees Fahrenheit just this weekend so it will probably be a colder winter. I need to do something with this plant to keep it happy and healthy through this coming winter, and I do not think it will do well in its clay soil in a hanging basket outside as it would likely turn into a rosemary ice cube. Anyone had success or any good ideas on how to keep this plant going?

Update:

Also- when should I do anything with it? Were the needles a sign of it needing to be taken care of yet or not? Highs got up to 65 today and lows will probable be in the 30s again. Should I start bringing it in just for the night or...?

    You did not say what size container it is in. It should be a 12" basket or pot. Remove the poor soil and re-plant in an all purpose potting soil. You can let it dry between watering but don't neglect it. My rosemary is in the ground and survives our mild winter. It can take a light freeze. Re-pot with good soil. take care of it and leave it out until your night time temperatures start getting below freezing. Bring it in at night. If the days warm up above freezing you can bring it out and put it in the sun. When you can no longer put it out keep it in the sunniest window in the house. Pay attention to your watering. Indoor heat can dry out the soil quickly.

    Good luck

    I would suggest bringing in your rosemary when the nights are in the low 40s to prevent the leaves from falling off due to low temps. But if it has been okay so far, then best to be on the safe side and keep it in a night.

    Rosemary needs full direct sun all day inside. Your may loose part of the plant if the light levels are too low. It also needs high humidity, but if you mist it without proper air circulation, it can develop a fungus called powdery mildew, which will kill the plant.

    Good luck with it.
