I have some silver birch that have been doing very well. They are 2-3 years old approx. All of a sudden the leaves on one or two of them are turning yellow and another one is wilting. It is drooping quite badly – about 1/3 of the tree is hanging low. I watered it but it doesn’t seem to have improved. What could the problem be?
