I have an 11 year old sugar maple. For the past few years the leaves have been getting more and more yellow. I bought an iron product, read the directions, and sprinkled it around the base. Instead of turning green the leaves are still yellow and small brown spots all over them. Help!

It appears that the tree is suffering from iron chlorosis. Enough iron is present in the soil, but it is in a form the maple is unable to uptake. Conditions that make iron chlorosis worse include excessive irrigation and cool, moist weather. There are no simple solutions to treat the problem. It is best to plant species that are more adapted to our soil. However, a soil application of chelated iron containing EDDHA as soon as the snow melts off or at least before the tree leafs out in the spring is a good option. Other forms of iron (EDTA or iron sulfate) generally are bound up in the soil too quickly to be effective. This type of treatmetn is good for one year only.
If this does not correct the problem, trunk injections are another option. They can last 2-3 years but injure the tree somewhat.
Keep in mind that treating iron chlorosis can be tricky and success is not guaranteed

- I have two maple trees in my parking strip. I believe they are the Autumn Blaze variety. They have a light green to yellow small leaf. The leaves are starting to die as if it needs water. They are spotted and turning brown and brittle. The branches are still green when I scrape the them. I do not think it is under heat stress since June has been mostly wet. We spoke with someone who lives about a mile from us who had the same problem last year and now the top of his tree is dead. We did see two other trees in his neighborhood with the same problem. It looks as though next year we may have the same dead trees if we do not do something to prevent them from dying. Can you tell me what is wrong and what I can do to save the trees?
