I can't tell if this tree is grafted or not. It also has several weird marks on it. I'm not sure if they are animal bites (squirrel). Or if it's infection and something I should be concerned about. I was excited to find this tree as it already has 12 oranges on it.

Are these marks (holes, scrapes??) something I should watch? Can infection or fungus set in? Should I paint the trunk 50/50 white paint and water?

Of course I didn't notice these at the nursery, only when I got home and repotted it. Thanks all.
