  • The Trellis System
  • The trellis system has two opposite angled posts. These support the wires and the permanent netting situated under the fruiting zone.
  • The inter rows are trenched. The unshaded side faces north in order to be perpendicular to the sun for the majority of the growing season and also gain more interception later in the season (this trellis system means varieties ripen even later than usual). This helps to warm the roots and promote ripening.
  • The vines single cordon and are planted every 0.65m in order to increase competition. They are trained up to the top wire on the north side – top of the short post.
  • Naturally the vines want to sprawl everywhere
  • For example:
  • The canes will then eventually end up all over the ground which is not desirable
  • The first tucking wires is then lifted from the ground on the short post side and is hooked into clips halfway up the tall post. The canes are then poking out the back side of the trellis and the fruit is hanging in the netting. A second tucking wire is done later in the season once upward growing shoots are becoming a problem.
  • By the time the whole vineyard is done the canes are long enough to be lifted. A lifting wire is lifted and clipped in 2/3rds of the way up the tall post .The draping canes out the back of the trellis are now contained between two high wires and a small amount is poking out the top.
  • By the time the whole vineyard is lifted the canes are too long again. The canes are then trimmed at the red line. This is done with a petrol hedge trimmer which must be carried upside down above the head, then walk down the rows.
  • This trellis system is incredibly labour intensive.
    If anyone has any questions about this system ask me in person as it is kinda hard to explain in text
