0F is still ok.

However..

Trees also do not like to move from summer to winter overnight. So moving it from a warm house into oF will do loads of harm, probably death. It needs several weeks of fall wweather to prepare for winter.

For now.. Do you have an unheated, frost-free cold space with lots of light where you can put it?
