All of the outer leaves on a cottonless cottonwood tree that I planted 2 years ago are turning a very light green. You can see the leaf veins through these leaves. The inner most leaves are still a dark green. Any suggustions?

New growth is often a lighter green than the more mature leaves. They should darken as they harden or mature - about 2 weeks. If you see no improvement in their color after a few weeks, it may be that the soil's pH is a bit off. Soil that is too acidic or too alkaline can bind up nutrients and make them unavailable to the roots. In this case you can sprinkle some Ironite over the root system and water it in well. The iron should help the leaves green up. Use amounts and with the frequency as recommended on the label.

Good luck with your cottonwood tree!
