Grape growing can be a big project for the inexperienced. Grapes need a good amount of light and room to grow without vines entangling each other. A trellis helps the grape vine grow thick and strong, prevents a small grape yield and minimizes disease. Growing grapes on a trellis system not only makes for the best growing conditions, it almost simplifies harvesting the grapes. Building a trellis is not difficult and costs little.
Place and end post at each end of your desired growth area.
Measure the length of your growing area and determine the spacing of the trellis posts.
Place a post every 21, 24 or 28 feet. Determine where the posts will be placed according to your measurements and the growing area.
Dig a hole for the end posts that is 3 to 4 feet deep, making the hole so the post is sitting at a 60-degree angle away from the rest of the trellis.
Place the earth anchor into the ground and attach it to the end post using a brace wire.
Dig a 2-foot deep hole for the first line post and sink the post in so that it is standing straight. Fill the hole. Repeat for the other line posts.
Drill a hole for your high tension wire at the top of the line posts and feed the wire through. Do this again for a second wire about a quarter of the way down the post. Attach the wire to the end posts by drilling a hole through them, running the wire through the hole then through the anchor loop. Pull the slack away, then twist the ends of the two wires around each other.
