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.
