How Do I Train a Grapevine on a Wall or Trellis?

Training a young grapevine correctly in its first two to three years creates a permanent framework that will produce fruit reliably for decades. A badly trained vine — one that has been allowed to grow without direction — becomes a tangled mass of unproductive old wood, difficult to manage and typically poor-cropping. The three years of patient, directed growth required to establish a good framework is the most important investment you make in your vine.

Setting up the support system

Fix horizontal wires to a wall or post-and-wire trellis at 30 cm intervals, starting 40–50 cm from the ground and extending to the full height you want the vine to reach. Use tensioned galvanised wire or proprietary vine training wire fixed with vine eyes or staples. The wires need to be strong enough to support a vine carrying a full crop — heavier than you might expect. Freestanding trellises need stout posts (at least 7 cm diameter) set 60 cm into the ground.

Year one — single rod to the first wire

In the first growing season, select the strongest shoot from the young plant and tie it vertically to a cane running up to the first wire. Remove all other shoots from the base. At the end of the season, cut this vertical rod back by half to encourage strong, well-ripened growth. If the vine produced very little growth in year one, cut it back harder — to two or three buds from the base — to start again with a stronger rod in year two.

Year two — establishing the first arms

In year two, train the main rod upward to the next wire. When it reaches the wire level, train two side shoots — the arms — horizontally along the wire in opposite directions. Remove other laterals. In winter of year two, cut the horizontal arms back by about half. The main rod continues upward to the next wire in year three, and the process is repeated to fill the available space progressively.

Rod-and-spur system for wall-trained vines

Once the framework is established, the rod-and-spur system develops spur positions along the horizontal arms at 20–30 cm intervals. Each spur carries one or two fruiting laterals in summer. This is the classic system for greenhouse and wall-trained vines. It is simple to manage, produces an attractive fan of growth, and allows each spur position to be replaced over time by cutting back harder to a lower replacement bud.

Training on an open trellis or pergola

A vine trained over a pergola or archway follows the same principles — a single main trunk taken up to the top of the structure, then arms trained horizontally across the top. Fruiting spurs hang down from the horizontal framework. This approach produces fruit at a comfortable picking height and creates impressive garden structures, though the vine takes four to five years to cover the full span.
