rescued tree

Hey, I just picked up a new globosa nana from a nursery, half of the foliage on the side the sun was on for most of the day is a pale yellow. I brought it home and replanted it and I was wondering if you guys had any more tips to throw my way or and advice. I have no idea what direction I want...

So, to keep it brief, a gutter fell off of my apartment building, and the next morning I found a white mulberry tree that had been growing in the gutter for a number of years. the leaves were limp but still green, it's now in a pot with some soil, but hasn't perked up after about a day or so...

Had this chinese elm a couple of years now arrived in bad health and probably the worst soil I have ever seen, still not fully there but its one of my favourites as I have become to attached

Last summer I found a mugo pine thrown in a corner lot here in my area. It was maybe used as a hedge and the owner might have dug and threw it, hoping that the trash collector would clean it. Luckily a bonsaist came to rescue it... :) I was so glad that it had a small rootball that was intact...
