Have I lost my Grafted Birch???
Lovely resource you have here. After exhausting my own research on this topic I have decided to create a thread.
I inherited a grafted birch that I do love very much, however I think I may be losing her. I will give you a timeline of its decline and share some images so that you may help me diagnose and treat if possible. I researched borers and canker disease but I am just not seeing it with the eyes of an amateur.
I am in South Central Pennsylvania.
*After the 'Polar Vortex' I had a lot of things die back (nandina, crepe myrtles etc.), but they all came back. When the grafted birch leafed out, it only did so on about half the tree. I am not sure if we had an early season freeze that may have impacted a full-leafout, but that could have occurred. The branches closer to the trunk seemed to have fared better than the ends of the limbs.
*The half of the tree that came back leafed out nicely, but we had a sneaky drought the past few months and the remaining leaves yellowed and died. I did add extra water at this time, but not enough and the tree sits on a hill side where water rolls off.
So what do you think? Is it possible it got stressed and went dormant early, and will come back next year? Do you see evidence of infestation or disease? Any thoughts are welcome and I thank you in advance for any and all posts!
