Betula populifolia Gray birchCulture: Gray birch is tolerant of poor soils and may develop chlorosis on high pH soils. Like other birches, it is best transplanted in the spring. Leaf miners are a problem on gray birch. This species has some resistance to bronze birch borers but it is still susceptible to injury. Usage: This is a good tree for naturalizing but not for the modern landscape due to the pest problems. It is native to the eastern U.S. and is a pioneer species that is naturally short-lived. |
