How To Build A Grape Vine Support Trellis. The MOST Popular Type.

Introduction

In this tutorial, we will guide you through building a popular grapevine support trellis. A well-constructed trellis is essential for growing healthy grapevines, allowing them to thrive and produce fruit efficiently. We'll cover the materials needed, the steps to set up the trellis, and tips to ensure a sturdy structure for your grape plants.

Step 1: Gather Your Materials

Before you start building, collect all necessary materials and tools:

• Materials
  • Number 10 gauge wire
  • Turnbuckles
  • Heavy-duty eye screws
  • Wire clamps
  • 4-inch by 8-foot long posts (number of posts depends on the number of grape plants; typically one post for every 12 feet)
• Tools
  • Drill
  • Fencing staples
  • Impact driver or similar tool
  • Measuring tape
  • Tamping tool

Step 2: Prepare the Posts

Follow these steps to set up your posts:

1. Determine Post Placement: For three grape plants spaced 12 feet apart, you will need four posts.
2. Dig Holes: Dig holes for each post, ensuring they are about 2 feet deep for stability.
3. Install Posts: Place the posts into the holes, ensuring they are upright. Backfill with dirt and tamp down to secure them in place. No concrete is needed.

Step 3: Understand the Trellis System

Familiarize yourself with the trellis design:

• This is a mid-cordon trained vertical shoot positioned trellis system.
• The first wire will be placed 42 inches above the ground.
• Additional wires will be added to support the growth of shoots and fruit.

Step 4: Install the Wires

1. Drill Holes: For the top and bottom wires, drill holes straight through the posts.
2. Pre-drill for Eye Screws: About 8 inches above the ground, pre-drill holes for the eye screws.
3. String the Bottom Wire:
   • Thread the wire through the hole in the bottom of the post.
   • Run it down the line to the next post and secure it to the eye screw.
   • Make sure the wire is taut, and cut it 6-8 inches past the eye screw before attaching with a wire rope clamp.

Step 5: Create Structural Support

1. Add Triangular Braces:
   • Cut a pipe and notch it to fit against the pole.
   • Run wire over the top of the pipe and anchor it down. This forms a triangle that stabilizes the post.
2. Install Turnbuckles:
   • Connect a short piece of wire from the bottom of the post to the turnbuckle.
   • Tighten the turnbuckle to keep the wire taut and secure.

Step 6: Install Catch Wires

1. Position Eye Screws: Place eye screws 8 inches above the bottom wire on each side of the post.
2. Run Catch Wires:
   • Run wires down from the eye screws on both sides of the post.
   • Secure the ends of the wires to the eye screws.

Step 7: Final Adjustments

• As you complete the trellis, check the tension of the wires and adjust as needed.
• If necessary, add additional sets of catch wires for better support, typically spaced about 10 inches apart.

Conclusion

By following these steps, you will successfully build a sturdy grapevine trellis that supports healthy growth and fruit production. Remember to monitor your trellis for any adjustments needed over time.
