1. A lean that got worse
A tree that has always leaned the same way is usually fine — it grew that way and built wood to support it. A lean that is new, or that increased after a storm, is a different story. In Middleburg's loose sandy soil the root plate can shift without the tree showing any canopy damage at all. Take a photo from the same spot each month; a change you cannot see day to day shows up fast in pictures.
