Birch is a popular landscape tree planted in Minnesota. The variations in bark texture and color, as well as foliage characteristics of the different species and cultivars, make them highly attractive landscape specimens. Unfortunately, birch are often stressed in the urban environment and become susceptible to a devastating insect, the bronze birch borer (Agrilus anxius). Fortunately, there are ways to reduce problems with this pest through proper tree and site selection, cultural practices and direct control of the bronze birch borer.
