When should I start protecting my palms and banana trees for the winter. When I saw burlap at the garden centre this summer I bought tons because last fall it was difficult to find any. I had to go to a fabric store. Although the burlap alone I wrapped around my med fan palms that are in the ground didn't survive that Jan cold snap. Should I also wrap them with bubble wrap or can you suggest a better way to protect the new ones I replaced them with. They were in 5g pots when I bought them. They did quite well and it would be a shame to loose them too.
