Gianni,
You might try treating it with chelated iron. It may need the iron less than the other micro-nutrients (magnesium and manganese) usually found those preparations. I've been told the Noemaricas grows in soils high int Mg and Mn.

That's really strange. I've never seen a Neomarica behave like that. I
wonder if there is a something wrong with the rhizome or roots? Maybe a
pest? or a fungus? mealy bugs?
In my experience Neomarica is really forgiving. It does not require
strict conditions, like an orchid or something. So for Neomarica to
struggle is a really confusing situation for me.
