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

- My husband plants tomato and peppers etc each year. He plants directly under the eves of the house and the water runs off the roof with each rain storm or in the spring run off. I believe this is not good for the soil he is planting the garden in since we have an asphalt roof and I can see the debris from the roof on the soil. He says not a problem, I still have a hard time eating them without thinking I am getting some sort of poison in our systems. Suggestions?
- We just planted a maple tree in our back yard and noticed today that almost every single leaf has large circular spots that appear to have been "eaten" out of the sides of the leaves. I've read about a tar disease, but I don't really see the tar on the leaves. What could it be and is there something we should do about it?

- I have a young (~3 year old) brown turkey fig. I planted it last fall and it survived! the winter. It is producing small figs now but the leaves have a brownish gray powdery looking substance on them. It doesn't rub off but looks like powdery spots. Any clue what it might be or what I should do? The leaves remain green and look healthy. This appeared after the recent heavy rains.
- Two questions; I have an dwarf Honey Crisp apple tree that is about 5 years old. Last year it had a dozen apples. I didn't disturb the fruit spurs when I picked the fruit. This year there were no blossoms on the tree. I didn't prune it at all. What can I do to help it produce every year? Second question; I have peach borers in the main branches of my nectarine tree. The tree seems healthy other than the borers. What can I do about them at this point? Will it help to dig them out? Will it help to spray? Will they winter over to next year?

- My Grandmother has several apple tree saplings that she has grown from seeds. She has offered one of the saplings to us. We want to know what time of year is the best for transplanting? Should we dig it out this fall and keep it in the garage until spring? Or could we transplant at the end of September? Is there a transplanting guide? Thank You For Your Time!
