Correcting an iron chlorosis problem is difficult. Lowering the soil pH to 6.0 to 6.5 would allow the roots of the river birch to more readily absorb iron in the soil.
Why are my birch leaves yellow?
Birch trees require iron to grow and produce leaves. If your birch isn't receiving sufficient iron, the leaves of your birch tree will emerge as yellow and may be stunted or contorted. The confusing part is that your soil may contain sufficient iron: Iron chlorosis occurs if the iron isn't available in a form that the birch's root system absorbs.

What is the pH of birch soil?
Ideally, the pH of the soil should be between five to 6.5. Some birch trees, such as the White-barked birch trees, grow well in alkaline, or high pH, soils. However, the River birch develops chlorosis in alkaline soils with a pH higher than 6.5. This is most likely the reason for yellowing leaves in river birch trees.
