Q: The leaves on my newly planted oak tree have numerous holes, and the edges of the leaf are missing. I do not see any insects, but I am worried about the tree. Most of the tree is like this.
A: Oaks are pretty tolerant of many insect pests. Holes in the leaf can be caused by insects or by diseases such as anthracnose that kill areas of the leaf, which eventually fall out, leaving the holes.
