Muscadine wine and the southeast go together like potatoes and Idaho. Several generations back pretty much everyone around here grew Scuppernongs (bronze) grapes. When I was growing up many “old timers” still kept them religiously and they were known to provide homemade wine to their neighbors.  This tended to be much more acceptable that shinny or “moonshine”, even in dry counties.

The new Muscadine trellis
My great uncle had what he called “tamed Bullace” vines, which just meant he cultivated some wild black grapes and over the years he created a healthy, hardy home vinyard.  When the house was sold, the new residence cut them down and put a dog pen there.

I was exposed enough to this tradition that I kinda have it in my head that old southern ladies grow tomatoes and old southern men grow scuppernongs. That and the fact that I like a lil nip now and then made me search out some vines.

Wire through post around bolt
I try and use what I have, but these vines get big and heavy. I would recommend 12.5 gauge galvanized high tensile wire or larger.  You can attach it to your post pretty much anyway you like. I had two post with holes drilled in them at around 5′ and some heave duty bolts and washers from old telephone poles so that’s what I used. They sell this really cool locking anchor on amazon that if I had some I would have used.

The tensioner is a must in my opinion since without one it’s really hard to get thick wire tight enough from the start plus the weight will increase over time and the post may give some. I concrete my post using quickcrete instead of using a guy wire.
I got bare root stock so I soaked them for about an hour in a bucket of warmish water with seaweed/kelp juice (about 1 oz in 4 gallons) while I dug the holes. I planted the first one about 10′ away from the end post and the next one 20′ from there and so on. This alows each vine to grow up to the wire and go 10′ in each direction. I planted both polinators and females on this row
The holes don’t need to be that deep, just enough to cover the roots and an inch or so above. The roots grow long and shallow so when I plant, I train mine out toward the line they are growing. Depending on your soil condition, you might add alittle of this or that. I added a bit of compost to my heavy clay for increase draining and some rock dust to increase diversity of minerals. Thats about it. Water and mulch about two feet out from the plant. Some people leave thier vines alone the first year but I prune mine back to one central leader. I train this main vine up to the wire above using a cut sapling or bamboo stick. More on growing and fertilizing these guys later. I just wanted to do a quick post on the second set of vines. My other vines should be producing decent this year.
