Would Hi-Yield Iron Sulfate be good for yellowing Pin Oak Trees? At what rate should it be applied?

Answer:

Hi-Yield Iron Sulfate can be used anytime during the growing season to help prevent and reverse yellowing due to Iron Chlorosis. Per the product label, use ½ lb. for each 1 inch of trunk diameter. Spread out under branches and water in after application.
