Birch tree problems -Suggestions?
I have 3 birch trees (12-15yrs old) that I really love and enjoy. Last year noticed some smaller dead branches on 2:3. Then the oldest suddenly dropped 3 bigger branches, with live leaves. I’m concerned about the bronze birch borer. Questions include: 1-can someone evaluate the trees.... 2-what can be done?... 3-Is it possible to save any.....4-if it must be taken down, what steps to prevent further spread. 5-if I were to replant trees, how long do I have to wait, prep work needed? 6- suggestions for replacement? Thankyou for any helping, assistance.
