How to Grow Grapes on a Trellis


Before adding a grapevine to your garden, you must prepare a proper trellis in order to support the growing grapes. The trellis must be strong enough to hold the grapevine and the weight of the full grown grapes. American style grapes grow downward and are supported best on two single wires, one three feet from the ground and the other should be five feet above the ground. The fruit will hang down from the wire, like a curtain. First year grapevines will not likely produce grapes. With care and proper pruning, edible grapes should be produced in the second year.

Step 1

Set each end post 2 to 2 1/2 feet into the ground. It is not necessary to set the posts in concrete; however, if you plan extra-long rows, it is beneficial to secure the end posts using an anchor.

Step 2

Set line posts by inserting the T-posts 2 feet into the ground. Position a line post in between each plant, which is every 6 to 8 feet.

Step 3

Attach the wire to each end post using a wire vice. Drill two holes through each end post. The holes should be 3 feet from the ground and five feet from the ground.

Step 4

Insert the wire through the hole, then insert the wire vice. Screw in place.

Step 5

Secure the wire to the line post by using T-post clips.

Step 6

Plant grape plants 6 to 8 feet apart. As shoots grow taller, tie them to the bottom wire using a strip of cloth.

Step 7

Prune other shoots in an effort to create a curtain across the bottom wire. When the shoot reaches the top wire, tie it as well. Continue to maintain pruning.
