My Autumn Blaze maple leaves are light green with dark veins. I understand this is iron chlorosis and needs chelated iron or sulfur. Can't find chelated iron, but used a regular iron fertilizer (has some sulfur). Any further info would be appreciated. Don't want to lose 3-year-old tree.

I have some iron chelate, brand name: "Grow More" in Gardena, Calif. I originally got it from a local nursery, which unfortunately has gone out of business; the kids wouldn't take it over. Too sad, nice nursery. I'd try the net & see if you can get it there. Something I read about in a household garden tips, was to bury steel wool pads in the soil around plants that like iron. They rust & dissolve into the soil. I've tried it & it does seem to work. Don't use SOS or BRILLO, just plain steel wool like in the hardware store.
