The youngest leaves on one of my apple trees are turning yellow with the veins still green. Checking the chart that I sent for the Spring Pomona, I learned that it is a symptom of a deficiency of iron or manganese. But which? Working the chart backwards, looking for symptoms of either iron or manganese, I learned that if the plant is dropping leaves prematurely, it is reacting to too much water. Some leaves are dropping telling me that, with the excess water, either iron or manganese has become unavailable. Rain has fallen for five to six days per week here in Central Minnesota.
