looking for it in the form of dry powder or granules.

It seems that, in recent years, it's becoming harder and harder to find
single-nutrient fertilizers. �All I see are combinations. �However, even
the combinations are incomplete. �For example, most commercial citrus

There are plenty of agri supply emporiums that carry zinc sulfate,
perhaps your local Agway.
