Weird looking own root pattern
On my 2nd year jude the obscure own root from heirloom, I'm noticing a weird like brown stripes going down vertically almost like the wood is old, however this is the only branch coming from the ground, and all the other branches come from this one...so I'm sure it's very important. Don't mind the snow by the way, this was on here way before the winter. I would say it started end of summer. It feels rough when I rub my hands against it, and almost seems like the branch is outgrowing and stretching... Almost giving a "ripping effect". I'll attach some pictures, this is worrying me because it's my favorite rose!! Well, one of them haha.
Thanks for the help, and I hope to diagnose/solve this issue with my own root jude.
