Q.Plant in shock
I have a Norfolk Pine which is about 3 foot wide by 3 foot tall. I put it outside and forgot to bring it in for the evening. The next day the limbs were just hanging down and were a dark green. They had been perky and a light green color. Is there anything I can do to bring it out of shock?

Norfolk Island Pine are subtropical and cannot be exposed to temperatures below 35 degrees F.
If you plant was exposed to temperatures this cold, you will need to wait and see what damage incurs.
It can take days or even weeks to see the extent of the damage.
