I am a fist-time backyard vintner in Wiley Ford, West Virginia. I planted 100 Cabernet Sauvignon vines in the spring. Some of the leaves are now turning a maroon color. Is this normal? It is only happening to some of my vines. I have a fairly serious problem with Spotted Lanternflies, and I’ve been spraying neem oil on the vines. Can anyone offer advice as to what is happening/what I should do?
