You were shooting at 225mm which is quite a large focal length.
This will give you shallow DOF even at f9.

According to the DOF calculator, on a crop body, say, at 20m away,
the DOF is less than 3 metres and only about 1.6m behind the focus
plane.

So you are implying that the tree is leaning? The top is more than
1.6m farther back than the front? I find that very unlikely.

well, just to be sure, one should shoot some house wall, holiding the lens straight.
