Canopy management

  • Hass on Zutano 14m X 14m
  • Hass on Dusa 7m X 7m
  • Managed as individuals in grid
  • Max height of trees is 7m
  • Light interception is the highest priority when pruning followed by structural tree balance, increasing access for picking and spraying, management of crop load and removal of dead or diseased material.
