Need help with texturing tree

I cant find anything on this (Not sure where to look) But i find it difficult to texture tree’s or anything that isn’t a plain.

Any help (And feedback or tips) would be extremely appreciated.

I guess it depends on what the tree mesh is like. If you have lots of “tubes” as trunk and branches you could just auto-tube wrap the texture. If it is modeled as one mesh you might need to UV-unwrap it.
