Q.Saving a Ti plant
My Ti plant recently went thru a freezing night, and has since turned brown, i dont know if i should trim it down to ground or will it come back? I have another one that was shielded from some of the wind , and it also turned brown but the leaves has recently started to turn back bright red,so how should I proceed and what should I expect

I would make sure to cover it with burlap, canvas, or a sheet on the cold nights like that. They can't tolerate temps. below 50 degrees F. I would not trim until warmer temps. return, but if it remains below 50 for too long, then the plant will die completely.
