I planted this oak tree two years ago with absolutely no gardening experience and have only just discovered that I did it all wrong (should’ve put the stake in at a 45 degree angle rather than straight and was supposed to leave an area without grass around it). I’ve taken the stake out now as it seems they shouldn’t be in for two years but I’m not sure what to do about how it leans to one side.
How do I get it to straighten up? Are there too many branches on one side only? Any guidance would be very much appreciated.
