Tree fern in winter
I have a tree fern in a pot and usually pop it into the greenhouse over winter and so far so good. This year however I may not get it into the gh as it has been potted up into a larger pot, I know they can stand quite a low drop in temp but should I put the pot into a fleece bag to protect the roots and also I usually pop some straw into the crown to protect new growth so not sure what to do. Would you wrap the whole plant up or not?
I do live in Devon close to the sea so our winter temp doesn't go that low
