Q.What Is Eating My Hops Vine?
It is 10 years old, no problems. Last year, something left the vine as a skeleton. This year, all was fine for the first month, now it’s being eaten again. I have searched morning, noon and night, and cannot find a single bug or worm on the leaves. I have sprayed 3 times with my Neem oil, and nothing is working. My silver lace vine is fine. HELP
