Can I use Yates chelated iron as a foliar spray on lemon, mandarin and cumquat?

My trees are showing chlorosis of the leaves - green veins in a yellow leaf, particularly in the newer leaves. The soil is clay, and although I have not tested it, I think it is of neutral pH. The trees have received twice yearly doses of magnesium sulphate and ammonium sulphate. One Google site tells me that iron does not move readily in citrus, so use foliar. Another tells me that citrus leaves are poisoned by iron. As a result, I have done nothing!

Hi John,

Yates Chelated Iron should be dissolved in water and applied to the soil. It is then absorbed into the root system in available chelated form. It will not change the soil acidity but will correct iron deficiency within the plant. The symptoms you have described sound exactly like iron deficiency so I am sure you will see an improvement in the health of the trees.
