I have a bunch of T. Fortunei seedlings and I am wondering how I should protect them in the winter here in zone 6 Massachusetts. I also have one older T Fortunei with about a foot of trunk that I need to protect. Oh and last but not least a needle palm that is about a foot tall overall. I need a way to protect all of these palms, but I don't want to go overboard because eventually I want them to be able to fight the winter on their own (when they get older and are more like trees). Any advice and help would be great! Thank you!
