I wonder why they would suggest iron. IIRC chlorophyll has magnesium and not iron as part of its structure, although there are a lot of important compounds that do use iron. I am not trained in plant physiology which is why I was asking. I know gardeners like to use iron and suggest putting down a rusty piece of metal to supply iron or other metals. I have not asked our county extension office, but due to the presence of iron containing stone and also red clay within our acid soil I assumed that there was enough iron locally for us.
