I did not realize they were only houseplants & left mine outside when the temp was freezing. A). Will it survive? The top is brown/probably dead. However, the lower & inside branches still look green. B). If it survives, how do I prune it to its best health? It is now inside in a south window. Thanks.

This will have to be pruned out AFTER it recovers. It will likely recover, but the shape of the tree will change. Just care for it indoors, and once you see new growth, you can prune away the old.
