I Am So Dense!
This year I found borers killing my Stella cherry, that seem to be flat-headed apple borers. At least, that's what they look like. So I kept wondering how did they get into the cherry tree? And now I have to take down two trees in two years, after the old apple tree died ...
But I looked and looked, never saw any signs of borers on the apple, only the cherry, the way it oozes gum.
Now I have to worry where they'll hit next, and how to find them, and how to prevent them.
