Background

  • The Almond is very closely related to the peach.
  • Almonds belong to the Rose family (Rosaceae).
  • They are believed to have originated in Asia.
  • Almonds have short chilling requirements (300 hours below 7degC). Once this cold requirement is me tthe tree will start to bloom.
  • Blossoms and small nuts on the trees can be damaged or killed by frosts and therefore need protection.
  • Good crop yields require additional irrigation.
  • The almond tree can grow 6-9 m in height.
  • The tree flowers in late Winter or in early Spring.
  • Bees are important pollinators for almond trees.
  • Trees will start bearing fruit at 3-4 years of age. They may continue to bear fruit for more than 50 years.

Cultivation

  • Almonds need well drained soils.
  • They are drought resistant, but will not produce nuts if there is a water deficit.
  • Organic fertiliser should be applied in both autumn and spring.

Training

  • Bare rooted almonds should be planted in early winter.
  • If the tree is planted late in the season it may remain dormant.
  • Select four main branches at different levels on the trunk approximately 10-15cm apart.
  • Allow for an addition 2-3 main branches at shoulder height on the trunk.
  • Train to an open vase shape.
  • Each main branch should have an additional 2-3 secondary branches.
  • General pruning should consist of thinning old laterals and inward growing branches.
  • In summer prune lightly, approximately every 2 weeks to remove undesirable growth.
  • Older trees can be pruned more heavily to open up the centre of the tree.

Harvesting

  • Nuts begin to dry in early autumn.
  • Harvesting time is signalled when a few nut hulls have split and a few nuts have begun to fall.
  • When harvested hulls should be removed.
  • Dry exposed nuts in the sun. Nuts are sufficiently dry when the shell can be snapped.
  • Nuts will keep for 1 year.

Pests and Diseases

  • Wood-boring bettles (insects)
  • Moth larvae
  • Shothole (fungal infection)
  • rust on leaves (fungal disease)
  • Gummosis (bacterial disease)
  • Crown gall (bacterial infection)

Propagation

  • Budding onto almond or peach root stock.
