TIPS FOR VINEYARD WORKERS

Similarities and differences with regard to pruning and canopy management of Smart-Dyson and “balletrok” trellis systems.

1.   Smart-Dyson

1.1 Pruning

  • Space bearers upwards, 10 – 12 cm apart.
  • Space bearers downwards (horizontally to straight down), 10 – 12 cm apart.
  • Prune bearers with two buds.

1.2 Shoots positioned to one side

  • ±50 cm shoot length, tuck in upright shoots between foliage wires and leave lateral shoots outside foliage wires.
  • ±100 cm shoot length, tuck in upright shoots between foliage wires.
  • Separate lateral shoots from foliage and allow bottom foliage wire to rest on bottom shoots.
  • ± After two weeks the bottom foliage wire may be fastened 30 cm below the cordon in order to position the shoots straight down.
  • Only tip/top upright shoots.

2.   Balletrok

2.1 Pruning

  • Space bearers to the left, 10 – 12 cm apart.
  • Space bearers to the right, 10 – 12 cm apart.
  • Prune bearers with two buds.

2.2 Shoots positioned to both sides

  • ±50 cm shoot length, tuck in upright shoots between foliage wires and leave lateral shoots outside foliage wires.
  • ±100 cm shoot length, tuck in upright shoots between foliage wires.
  • Separate lateral shoots from foliage and allow to hang at approximately 90º.
  • If shoots do not remain at 90º by themselves, it is too early to let the shoots hang downwards.
  • As the shoots and bunches become heavier, the bottom shoots are pulled increasingly downwards. Shoots slant downwards.
  • Only tip/top upright shoots.
