Mine too… just reading about what was originally asked was the split on the trunk. I have to agree wisteria are very invasive if not kept in check. I am guilty of have them in the front of my entry door and across the front of the garage doors for over 25 years. As much as I hate constantly trimming them I have to admit they add needed shade especially since climate change they shade with summer temps off the charts, and they put on a beautiful spring show.
I planted it in earlier years when I didn't know any better. But now yikes…Every year I threaten them that this is the year I will take the whole plant out. I have trunks on them as big as a small tree that are split and they heal over just fine. Just leave the trunk area alone it will heal over in no time.
Warning ⚠️ they need to be trimmed vigorously 4-5 times or more during the growing season.
