North Central IL | Hey timber, I have a yard ash that's ~15 years old. It probably had borers in it when I acquired it 3 years ago. Since then I've been treating it with the Bayer blue jug. Last growing season the tree still "looked" 100% healthy as far as foliage goes. This year it leafed out normally, but since then all the leaves have a shrunken, shriveled look. Where all the new growth has emerged on the ends of limbs this summer, those leaves are large and normal in appearance. Is this most likely a late frost damage, or borer death setting in, or could a Bayer overdose do this? I OD'd it a little this year. Looking up into the tree I can see where borer damaged limbs have tried to heal since I started treating it. | |
