Are Your Birch Trees Suffering or Dying? Could be a Bronze Birch Borer Infestation

We've noticed quite a few Birch trees around Seattle beginning to die. Often the top of the tree will dye first, and before you know it, the whole tree looks like it's in decline.

The major culprit: Bronze Birch Borer

Prevention:
- deeply water your Birches once per month in dry weather
- mulch around the roots
- have a professional drench the roots with a pesticide once a year

If your Birch tree shows 30%+ dead, it is unlikely to recover and should be removed.
