Hi, So sorry it's taken so long to get back to you, but our Garden Doctor system has been in repair for about a month. Anyway, the best thing to do is to bring your angel's trumpet indoors before it freezes and then keep it in a cool, bright location. It may go dormant for you and if it does, you can prune off a bit of the top if you like. Otherwise, leave it alone and just keep the soil barely moist, but not wet.
