Why are my tree’s leaves turning yellow in color?

Your tree’s leaves turning yellow could be due to a condition called iron chlorosis. This condition occurs when iron in the soil is either deficient or unavailable to trees. As observed, it can turn your tree’s leaves yellow, but it can also scorch the leaves and turn them brown as they die.

It’s important to remember that there are many other causes of leaf discoloration so it is best to call an arborist to determine the exact cause.
