As a basic rule, most bonsai trees need protection from the cold. Even bonsai trees that are considered hardy in the cold should be protected from the cold if they have recently been transplanted or if the weight of the snow could potentially break their branches. There are many places with bonsai trees for sale, and after you find the perfect bonsai tree, you will need to know how to care for it during the winter. All bonsai trees that are susceptible to the cold weather should be positioned in a location where they will not be subject to direct sunlight and be well protected from the cold. Extra precaution needs to be taken when dealing with Japanese Maple and Trident Maple, as these tree are native to warm climates have little resistance to the cold.
The easiest option for protecting your bonsai is to place them under an eave or near a window, where they the tree will be better protected from the rain, wind, snow, frost, and colder temperatures. You can also place your bonsai in an unheated greenhouse or sunroom that will provide a decent amount of warmth and protection. Some people choose to construct a shelter with waterproof cloth that is closed off on all sides except the south (for some air and sunlight). Some “hardcore” bonsai enthusiasts choose to build a shelter for the bonsai tree after digging a trench in the ground in a location with acceptable drainage. This option gives the bonsai the protection of the shelter and warmth of the earth.
Most bonsai trees should be placed in the shelter, or location you have selected, after they have been exposed to a light frost once or twice. If you have a tree that is sensitive to cold weather, move to the shelter before the first frost. In the spring, you can move the bonsai back to its outdoor shelf once the temperatures have begun to warm.
