birch trees in arizona
Birches and aspens in general require a lot of water to do well, which you had in Zone 10 California but not in Zone 7 Kingman, Arizona. Even when established, these trees have poor tolerance for drought. For a white-barked shrub or small tree, try Curleaf Mountain Mahogany (Cercocarpus ledifolius). It is a slow-grower and, like aspens and birches, makes a great windbreak, hedgerow, grouping or specimen.
