Not much available locally. I really wanted the liquid iron, but one place had some chelated iron. That didn't work when I lived in a place where many plants needed iron. As I understood it (a long time ago) the iron was actually in the soil, but other structures tied it up so it was unavailable to plants. When you used iron chelate, it promptly was bound up and didn't do what was needed. Liquid iron, on the other hand, was absorbed via the foliage and the effect could be seen overnight. There was another product today called 'Ironite', but it was only 1% iron and there were no instructions for using it other than as a hose-end application plus it had a LOT of other minerals included. I ended up buying iron pills. How much water to a crushed pill? For a spray or drip application to the foliage?
The upside was I found a bag of Milorganite at the lumber yard! I've wanted to try that for a while so I picked it up. But for now, I just want to put iron on those two seedlings and see.
