My 15 year old whitebeam tree has a tilt and this is getting worse. When we moved in 10 years ago it was already leaning slightly but was staked. I removed the stake a couple of years ago and after the winds recently it is now leaning at a more pronounced angle! It is also weighted to one side with the branches growing to one side which has made the lean worse. Any suggestions as to how to brace it, whether to brace it, take it out and plant something else etc? Suggestions gratefully received.
