Muscadine grapevines are native to the Southeastern United States, particularly North Carolina. With a musky aroma and a sweet juice, muscadines are used commonly for wine, jams and pies. These vines benefit a landscape not only with a tasty fruit harvest, but by having the ability to act as an architectural element of beauty on a trellis or as a privacy wall. A muscadine arbor is one of the more beautiful ways to support the vines, doubling as an entryway. When constructing your own arbor, take into consideration the size you want it to be and the location.
Use the post digger to dig four evenly spaced holes in the ground where you want the support for the arbor. On average, the size of an arbor is about 4 feet long and 3 feet wide. Dig the post holes about 2 feet deep and slightly smaller in diameter than the posts. Spread 1/2 lb. of gravel into the bottom of each hole.
Manually insert each post into the hole. Push and twist them slowly until the post's bottom has full contact with the bottom of the hole and they feel tight and sturdy. Once you are done, the arbor support system should resemble a square or rectangle of four posts.
Drill three holes into the front of each post, spacing them evenly apart. Fill in each hole with an eye screw. Take the steel wire and pull it through the first row of drilled eyes, pull it taut, cut it and twist around the post to secure tightly. Repeat this process with the second row and third row of eyes. Trim off any awkward or sharp pieces of the wire with the cutters.
Dig a hole next to each post that is just deep enough for each muscadine transplant. Make sure it isn't too close to the base of the post, or it will make the arbor unstable. Place the muscadine transplants into the holes. Backfill the soil and pack around the muscadine roots.
Train the muscadine vines, branches and tendrils up each post, securing them with plant ties or twine. The point is to eventually train the muscadine vines straight up and outward.
