The trellis is the main support structure of grape vines in the vineyard; it must be sturdy enough to support canopy and wind loads that exert forces on the catch and cordon wires, line posts, and end assemblies. … Tension from the trellis wires transfers to the end posts.

What is the purpose of a trellis?

A trellis is a simple framework of vertical supports and horizontal crosspieces that is flat and can train plants—like shrubs, small or young trees, or vines—to grow up and against an object.

How do you support a trellis?

Place the trellis against the stakes and secure it to the stakes with plastic zip ties or sturdy rope. A staked trellis works best using a metal trellis with two or three legs that touch the ground without a bottom framework, such as an arbor-style trellis. You need one stake per leg.
