My white oak tree is 4 years old. It is planted near water in Stearns County. We noticed this weekend that something is eating its leaves. Any ideas? The tree also looks very wilted.

Check your tree to see if insects are present, and then look at the photos in the attached link to see if any insects you find match those in the photos. Please send us a photo if you do find the insects.

Oak wilt is another concern. It's caused by an invasive fungus and usually results in death of the tree. Hopefully the wilting you see is due to insect feeding and not oak wilt. For information on this issue, see
