🌿 Trellis

A trellis is a row of posts with wire stretched between them. The vine grows along it, and the shoots and bunches are held up by it. Without support the vine would trail on the ground, and the berries would ripen poorly.

In a vineyard the trellis is placed along the rows. Posts are driven into the soil, and wires are stretched at different heights. In spring the shoots are tied to the wire. This gives the leaves more light and lets air move through the bunches.

The trellis decides how the vine is trained. Guyot training and cordon both rely on it: a cordon lies on the wire, and Guyot does not work without it. There is also another support, the pergola, where the vine runs over an overhead frame.

So the trellis is a basic part of grape growing. Pruning and harvest also go along it, because people and machines work along the trellis rows.
