Soon if not already, many people and especialy beginners who work with ch. elms in their collection, will start seeing changes in the leaves on their trees.
Almost all who have worked with these trees for a while have heard of the dreaded "Black Spot" that can over take them in no time. Just because your leaves are looking a little different at times on these trees doesn't mean you have blk. spot, especially if the leaves are older and more mature.
In my experience with these trees, blk spot will only affect new tender growth, and that's why you will mainly see this problem in the Spring and early Summer.
Here's a picture of what blk. spot looks like. If your leaves don't look like this, then you probably have something else going on. A couple of leaves on your tree like I found this morning on mine will not hurt the tree. It would be a good idea though to cut them off immediately and inspect the tree overall.
If your not in the habbit of routinely checking your trees, you might find that it has over taken the tree, and then you have problems.
Hope not too many of you find your trees with leaves that look like this one.
