Yellow Leaves on my Cherry Tree
The leaves are turning yellow on my (about 2 years old) cherry tree. They appear to have a brown or purple spots (i'm slightly color blind) on the leaves. Can you tell me what that might be and how I can treat it?

Hi, It is true that our dry winter and late spring snow has delayed many trees from leafing out. I can’t tell you what has affected your tree without a specimen or close in photographs. I suspect from your description that it is chlorosis, unspecified. If, you send photographs to the Ask an Expert site we may be able to determine what is stressing your fruit trees. There are specific pests to soft and stone fruits that might account for the yellowing and spots on the leaves. Observe if the yellowing is concentrated to a specific area, does it start on new growth or older leaves? Determine if the trees are getting sufficient water. Over watering can promote chlorosis. Is ther patten top down or bottom up? As you can see there are many variables in a diagnosis. I hope that this was somewhat helpful.
I have posted 2 pictures. As you can see by #196 the yellow leaves are scattered thru out the tree. #197 is the best I could do for a close up but if you can zoom in you will see the little spots near the tip of the leaf. Any directioninformation will be greatly appreciated. Thanks.
