Birch trees

Asked July 7, 2018, 10:56 AM EDT

I love birches and am thinking about planting one in my yard. But I've noticed so many dead and dying birches this year. What's up with that? Can you tell me? Thank you.

Birches are dying because they require water year-round. In Oregon, that means they must receive sufficient water during our dry months.

When trees don't receive sufficient water, they are stressed. Stressed trees are easy victims for secondary pests which deal the final blow to the tree. For birches, it's the bronze birch borer, Agrilus anxius.

Many thanks for your answer.
