Q.How to Grow Branch From Bush
I took a branch from a bush by the house to see what I could do with it. I want to know how to grow this branch.

It really depends on which kind of bush. Some kinds of plants will develop just by sticking the branch into the soil. Some bushes require grafting, which I've never tried. Some will grow by adding root hormone. And some? Some won't grow at all even if you add pixie dust to it. (Good luck finding pixie dust anyway. lol)
Now, try again, and let folks know which kind of bush you want to grow and you'll probably get a better answer next time. (Hey, I'm no expert. I just garden. lol)
