Not sure if this is the best section on the forum but here 'goes anyways. I planted this several years ago and has been healthy until last year. I built my porch 2 years ago and I think I cut a root when I was digging the hole for the posts. Oops! Well anyways, I don't know if that would have caused these problems or not. My guess is yes but then as I said, I'm not sure. I had a little bit of dieback last year and a more significant amount this spring when it bloomed out. Also, I tied it over for about a year and a half in an attempt to train the new growth in an direction away from the roof.
