I couldn't find a guide about the surrounding terrain. I already know that no overgrowth or undergrowth can be used but I wanted to know what I can put into the surrounding terrain

there aren't really any rules about it I think. It's just advisable to place much there, as the only function it will have will be to be a visual thing to look at. Unless if you make it playable area ofcourse which is also not really a good idea.

I would say place as less as possible, but try to make it not look too artificial going from normal terrain to surrounding. Meaning if your city stops, place a few buildings there too(like ramiel), or don't make a forrest abruptly stop,place a few static trees,... (like ia drang)

Ofcourse, I wasn't intended to design entire cities in the unplayable area and I was only planning to add a few trees and buildings

yeah that should be fine in my experience. And should make it look better

You can't put trees into the the surrounding terrain, but you can put the tree lods in there.
