North Georgia, near Atlanta, climate zone 7b.
(Top photo) I have a little vineyard in the front yard with 24 Cynthiana / Norton and 6 Lenoir / Old Spanish "Favorite" variety. I had a couple rows of Blanc du Bois, a white wine variety developed in Florida but it got hit by black rot so bad that I pulled them out and replanted with more Cynthiana. These are all trained to the high cordon system. The rows were planned to go around two nice dogwood trees that I couldn't bear to cut down but my thinking was that trees and grapes have learned to get along for many, many years, right? And it seems the vines closest to the trees are growing the best. All rows and paths are mulched with wood chips, the paths had cardboard laid down under the chips.
(Bottom photo) Muscadines - Ison (red) and Magnolia (bronze) varieties. I also have some 20-plus year old muscadines closer to the house planted using the Geneva Double Curtain system. Carlos and Triumph (bronze) and Southland (red). I've tried for years but Southland does not make good wine, it always has a 'green grape' taste no matter how careful I am to only use ripe fruit. But it makes great jelly.
It's been a good year for all my grapes. A problem that I need to somehow correct next year is that the hybrids Cynthiana and Old Spanish were way too vigorous! Which was surprising since they are planted in holes that I nearly had to blast down into heavy red clay. I hedged the rows in July and that only caused them to come back with a vengeance, sending out new shoots that even started to bloom again! I did not fertilize at all this year, btw, except a couple foliar sprays with seaweed fertilizer back way back when they were blooming.
Yesterday grapes gathered from both hybrids tested right at 20 Brix. I believe I'll be harvesting next week.
