Not all leaning trees are dangerous, but they can be a hazard as gravity may eventually cause them to fall. A key factor is whether the lean is new or has been present for a long time. Trees that have grown with a lean for years are not typically an immediate danger, but a sudden lean is a cause for concern as it often indicates weakening roots. If a tree is leaning more than 15% from vertical, you should consider having it straightened or transplanted. To be safe, it's always best to hire a professional arborist to inspect any leaning tree to assess the risk and avoid potential accidents.

Many species, especially when well-established, are not fans of transplantation. You’ll need to decide if you want to risk splashing the cash, understanding that transplantation isn’t always successful. Again, this is where hiring a pro is helpful, as they can give you all the essential info you need to ensure your tree stands a fighting chance.

You may also want to consult a professional arborist to make sure the tree is healthy.
