needrain,
Call ahead and check, and maybe check a feed and seed store. I went to a commercial daylily garden and they were using a product very similar to Milorganite purchased at a local feed store its granules were larger and I was told it was not processed to the degree milorganite is (don't know for sure it had iron)so, you would need to check and make sure it had Iron in it. Maybe the feed store or local nursery could suggest another source of Iron.
