Fertilizer--What is a lawn and fruit tree fertilizer with the most iron you can buy?

Question

I've used Ironite, but I'm looking for even more iron concentration. All answers appreciated. I live in the state of Idaho.

Answer 1

Iron sulphate, sometimes sold as "Iron-sul".

Answer 2

read here, especially the first link, that speaks of soil pH being directly associated with iron.... could be you only need to adjust that.... too much iron is not good, either.... chelated iron in any form gets the iron to the plants roots...w hether the plant can then uptake the iron is another matter altogether... look on some of these links to see more about your plants and iron deficiency....
