Mid North orchard 5

General management

  • Pollination, pest monitoring, spraying and fertiliser planning is contracted out. Remainder of work is completed by owners.

Canopy management

  • Tree spaced 8m X 8m
  • Trees are managed as rows
  • Max height of trees is 4-5m
  • The priority when pruning is light interception followed by structural tree balance, access for pickers and spraying, removal of dead and diseased material and management of crop load.
  • Structural pruning is carried out twice a year in spring and autumn. Fruit thinning is carried out once a year.

Soil and soil moisture management

  • Orchard is predominately clay loam of volcanic origin.
  • Leaf litter and avocado pruning are used to mulch trees.
  • Soil moisture is not monitored on the orchard.
  • The orchard is 100% irrigated with ground based micro sprinklers.
  • At peak summer it is common to irrigate for 2 hours per irrigation event more than twice a week using sprinklers with a 4m diameter that deliver 30l/hr (4.8mm per irrigation event)
  • Sprinkler heads are varied based on tree size and age.
  • Control valves have been checked in the last year and pipework is assessed on an ongoing basis including mainlines, sub-mains and laterals.


  • Pollinizer species are unknown but are at a percentage of 7-10%
  • Honey bee hives are brought onto the orchard at about 1-5% flowering at a rate of 8-10 hives per hectare. Hives are located evenly through block.

Soil and fertiliser application

  • Soil and leaf tests are carried out once a year in April.
  • A consultant provides a fertiliser plan based on test results and crop loading.
  • The majority of fertiliser is applied by ground application but foliar application is also used.
  • Boron fertilisers are applied as ground application and foliar every year.
  • Calcium fertiliser is applied when deficient.
  • Fertiliser in some form is applied 16 times a year.

Tree health management

  • Trees are injected and have foliar application of phosphonate more than twice a year with no root testing conducted to verify root concentration.

Frost protection

  • No frost protection is in place in the orchard.
