Hello,
Typically found in the United States, particularly from New Mexico to Tennessee, this plant makes a great choice for Bonsai. Because it is an elm, the tree can tolerate neglect, although it is not a good idea. While the Cedar Elm will do quite well in a number of zones, for the most success, you should live between zones 7 and 9.
The rough, fissured bark is one of the features making this a desired species for Bonsai. They can be found at nurseries, gardening centers, or on the internet but also found in the wild. The trunk and branches have an aged look that is perfect for Bonsai.
With Cedar Elms you need to be careful with the water in that they do not do well if too wet. Since they grow naturally in regions that are hot and arid, they will do best if kept more on the dry side. Additionally, with Elms and other trees, they do require more water during the springtime than any other time of the year.
