Mid North orchard 3

General management

  • Pollination, pruning and pest monitoring are all contracted out. Remainder of work is completed by owners.
  • Have a weather station on the orchard.

Canopy management

  • Tree spaced 7m X 7m
  • Managed in rows
  • Max height of trees is 7m
  • Crop load management in the form of flower or fruit removal is not carried out.

Soil and soil moisture management

  • Orchard is predominately clay loam.
  • Leaf litter and avocado pruning are used to mulch trees with some grass present as well. 1-3 year old trees also receive commercial mulch until leaf litter builds.
  • Soil moisture is monitored using tensiometer sites. A trigger point of -20 to -30kPa at a depth of 15-30cm is used to start irrigation.
  • The orchard is 100% irrigated with ground based microsprinklers.
  • At peak summer it is common to irrigate for 3 hours per irrigation event once a week using sprinklers with a 6m diameter that deliver 39l/hr (4mm per irrigation event)
  • Sprinkler heads and irrigation is varied based on tree age and size.
  • Pump pressure and flow characteristics, control valves and condition of all pipework is checked at least annually.


  • Zutano pollinizer trees are used in the orchard at a percentage of 1-5%
  • Both honey bee and bumble bee hives are brought onto the orchard at about 20% flowering at a rate of 5-7 hives per hectare. Hives are located equally in blocks in positions that have good access.

Soil and fertiliser application

  • Soil and leaf tests are carried out once a year in May.
  • 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 every year.
  • Calcium in the form of lime is applied every year.
  • Fertiliser in some form is applied 8-10 times a year.

Tree health management

  • Trees have 3 foliar applications of phosphonate a year after summer flush has hardened off. Root testing is conducted to verify application has been successful.

Frost protection

  • No frost protection is in place in the orchard.
