Hello russel the temp for the last two weeks in england has been 30 deg f and this is normal winter has only just started so we have a few more months left. the chineese Elm,3 Junipers,mugo pine, and hinoki cyprus will all be ok in winter times as they will sleep and store for next year . the thing i would worry about is thet you have been boing this for a couple of years and there cycles are going to be out of line so maybe build you self shelfs that you can put some winter protection around. and cover the pots in hay or somthing of the simular. to offer some protection. the tropicals could have the same done but in a glass house
