This time, we went all the way to charming Turner Valley.
Client´s birch tree was infested with Bronze Birch borer. The presence of bronze birch borer is characterized with thinning crown, discoloration of foliage, branch dieback in crown, holes in the bark and many other signs.
Damage generally begins near the upper part of the crown on branches measuring approximately 20 mm in diameter.
The best way to control birch borer is to maintain the health of your trees, as borers will normally not attack healthy trees. Sufficient water for birches is absolutely critical for their health. Birch are trees that are native to rivers, lakes, and other areas with high water levels. They do very poorly in drought conditions
