The leaves of my red oak have been turning a yellow/brown and then dying and falling off. I was told it was due to an iron deficiency. I was also told the soils in my area have a high pH and binds the iron in the soil so the roots cannot get the iron. I have noticed over the last two or three years that this tree has not been producing many leaves but never really thought that it was sick - until the leaves started dying and falling off! What can I do to save my tree?

Greetings Jason:
For temporary relief, you may wish to try iron chelate. For a longer term solution, you need to modify the soil pH by ammending the soil (adjacent to the tree) with sulfur or ammonium sulfate.
