That is a good idea about propping it up. I will just wait to put the awning up.
I have motorcycle tie downs but they are red. So I will put the 2x4 back and let it sit for a few days. Maybe it will relax where it is pushed too.
May look odd strapped up but to me it is better then cutting the whole branch. Besides I live in the mountain forest so no one to care what it looks like. If the zip tie doesn't work I guess I will get a chain and bolt it.
I love it's Fall color. It is a non fruit pistachio.
