Since your previous post said your soil was very high alkaline you don't have anything to loose and a lot to gain. Since it is a tree I would broadcast rather heavily all along the outer edges so you hit the feeder roots. I'm sure Josephine could be more specific. Same thing happened with a neighbors red oak some years ago and he used chelated iron. Took a while but it finally turned green. Did not know about ES at the time. I have used it on absolutely everthing this year and the results speak for themselves. The Japanese Maple has been in the same place for 3 years and only after using ES did it turn red for the first time. Check some of the links above and they give a more difinitive scientific explanation.
