Chinese Elm bonsai tree in 8" bonsai pot.

The Chinese elm thrives in either full sun and/or partial shade. In temperate climates, it can be left outdoors even during winter months. If you have an indoor Chinese Elm Bonsai you can place it outside during the summer, but it's best to bring it into a cool, but frost-free, room in the winter. The Chinese Elm can usually endure some frost but it differs depending on the region it was imported from. Trees from northern Chinese regions are more frost-hardy than those coming from southern areas. Depending on winter temperatures Chinese Elms either drop their leaves or keep them until spring when the new shoots emerge.
