Hello!

I’m in season one of growing grapes from rooted cuttings (Chambourcin, Vidal Blanc, Itasca, Catawba) and I’m located in middle TN. Thus far, pressure on the vines seems to be coming from Japanese beetles and possibly fungus, although some of the leaf discoloration may be from the heat/humidity combo. What are your best tried and true organic recommendations as far as a spray program? Just finished a second coating of Neem Max, but I’m not confident in its efficacy.
Another thing I’m curious about is irrigation. I’ve got drip lines established, but I’ve noticed several local vineyards don’t seem to have irrigation. Is it necessary? Only ask because I intend to expand the vineyard several acres next season.
Thanks for any advice!
