Herons Bonsai in the United Kingdom has a great video out titled “Overwintering Bonsai“. There are some really great suggestions on how to winter your Bonsai trees depending the species of the tree. I would never of thought of using Shade cloth during the winter or perhaps bubble wrap on a tree. There are lots more great ideas that could be used anywhere in the world. I have added the video to the Winter Care page under Bonsai Basics page.
