Q.On My Linden(I Think) The Leaves Are Full Of Raised Black Spots On Top And Bottom Of Leaves. What Is It?

Zone St Paul Mn | Lisa M Butterfield added on October 25, 2023 | Answered

My tree leaves on the top and bottom are full of black bumps. Also, many of the leaves look like they were chewed on or something. Seems worse on the very top the leaves are more loaded up there didn’t really notice it till about the last month and it was already pretty much full blown at this time.

This is characteristic of Black Spot. This fungus is treatable, however. There are several fungicides on the market, both natural and synthetic.
