Content Detail

Himalayan birch is very susceptible to bronze birch borer (Agrilus anxius). It was once used in landscapes, but its high susceptibility to the bronze birch borer has limited its use in more recent years. This species is not recommended for planting anywhere in the Midwest and usually requires removal due to its susceptibility to the borer.

This tree is native to the Himalayan Mountains in Nepal, but was introduced to the United States as an ornamental tree. As an alternative, river birch (Betula nigra) is a good option. Before purchasing or planting, be sure to check for any local or state guidelines on this species, and ensure that this plant is suitable for its habitat by checking its attributes at mortonarb.org or plants.usda.gov.
