I have a Silver Birch that has yellowing leaves and is now shedding them.
I have other Silver Birch not showing the same problem all sat close to each other, same amount of sun watering etc.
I am thinking it is a root related problem as the new emerging leaves are starting to shrivel up, so it suggests lack of water uptake to me, does anyone else think the same?
I am in northern France, summer is now upon us, if this is a root related problem, maybe pour balance of water & oxygen.
The tree hasn’t been repotted for over 2 years.
What would be my first cause of action, i am not thinking this would be a good time to repot?
thanks in advance,
