Australia currently imports most of its hazelnuts, presenting a significant opportunity for import replacement through the cultivation of fresh hazelnuts. Hazelnut trees are typically grown in temperate areas of south-eastern Australia, particularly in New South Wales, Victoria, and Tasmania. These trees require cross-pollination and compatible varieties to produce nuts. They also need chill hours over the winter and slightly acidic to neutral soil. With proper care and suitable growing conditions, hazelnut trees can become a valuable crop in Australia, providing a fresh and healthy product for local and international markets.

Soil requirements
Hazelnut trees are tolerant of a range of soil types, provided the soil is not poorly drained. The soil should be slightly acidic (pH 6.5) to neutral. Conducting a soil test is highly recommended before planting. Hazelnut trees have fibrous roots, which means they draw moisture primarily from the upper layer of soil. However, the deeper roots provide structural strength to resist wind damage.
When planting hazelnut trees, choose a sunny spot to ensure complete photosynthesis and the production of starches and sugars for the nut crop. Irrigation is beneficial when establishing an orchard to obtain large trees more quickly. Its main use later on is to ensure adequate soil moisture during the nut-filling stage, which occurs from December to February.
Hazelnut trees should be planted in commercial production when they are about six years old, and a well-managed orchard should remain active for 40 years or more. The trees typically take 15 years to become mature, reaching a size of 6m x 6m. Newer varieties of hazelnuts can be less spreading or pruned to allow closer spacing of 5m x 6m.
The temperate areas of south-eastern Australia, particularly the Central Tablelands of New South Wales around Orange, Narrandera, and northeast Victoria around Myrtleford, are ideal for growing hazelnut trees. They are also grown in central and eastern Victoria and increasingly in northern Tasmania, with small levels of production in South Australia and Western Australia.

Orchard layout
Soil Preparation and Testing:
Before establishing your orchard, it's essential to prepare the soil adequately. Clear the orchard floor of any brush and rocks. Conduct a soil test to determine its pH level and nutrient content. Hazelnuts prefer slightly acidic to neutral soil (pH 6.5), and they can tolerate a range of soil types as long as drainage is adequate. Adjust the soil pH with lime if needed and address any drainage issues. Ensure your soil has sufficient nutrients, especially macro and micro-nutrients, to support healthy tree growth.
Spacing and Density:
Proper spacing is crucial in your orchard layout. While you may be tempted to maximise land use by planting hazelnuts close together, consider the room needed around the orchard perimeter, between rows, and between trees within each row. Allow at least 25 feet on the edges of the orchard for equipment manoeuvrability, and up to 30 feet for bookends if necessary. The standard spacing for mature hazelnut trees is 6 metres by 6 metres, but newer varieties can be pruned to allow closer spacing of 5 metres by 6 metres.
To increase early yield, you can consider a high-density orchard with spacings like 10 x 20 feet or 12 x 18 feet, which can later be thinned out. However, be cautious not to crowd the trees, as this may impact their growth. Double-density planting with spacings of 20 x 10 feet for the first decade is an option, but it may lead to tighter spacing patterns and influence tree development.
Polliniser Placement:
As hazelnuts are wind-pollinated and self-incompatible, polliniser placement is critical. Nurseries can advise on compatible varieties. A common recommendation is to plant 8% of the new orchard as pollinisers, typically placing one out of every 12 trees as a polliniser. In a square pattern, this could mean placing a polliniser every third tree in every third row. For multiple pollinisers, repeat this pattern across the field. Ensure the maximum distance from the main cultivar to a polliniser is no more than 15-20 metres.
Planting Process:
Use modern technology like GPS grid planting to pinpoint exact tree planting locations. Mark the polliniser spaces first, as these are permanent. Then, plant the remaining trees according to your chosen spacing pattern. Hazelnut trees should be planted 10-12 inches deep in holes 18-24 inches wide.
Sun Exposure:
Choose a sunny aspect for your orchard to facilitate complete photosynthesis and the production of starches and sugars for the nut crop.
By following these instructions and considerations, you can design an effective orchard layout for growing hazelnuts in Australia.

Irrigation
Hazelnuts require a relatively cool, temperate, and typically Mediterranean climate. The average annual rainfall should be greater than 850mm, and supplementary irrigation should be available to ensure consistent soil moisture during key growth stages. If the annual rainfall is less than 850–900mm, irrigation is recommended for mature orchards. Depending on the region and soil type, growers should have access to about 3–8ML/ha of irrigation water. This ensures a consistent water supply during nut development.
To reduce watering requirements, it is recommended to place 5-7cm of mulch around the root zones of the trees. This helps suppress competition from grass and weeds while also increasing the growth rate. However, it is important to ensure that the mulch does not directly contact the tree trunk to prevent collar rot.
In addition to irrigation, it is important to consider the amount of chill required for optimum nut development. Hazelnut trees require specific chilling hours over winter to ensure nut set, so they are suited to cool climates. The required chill hours will vary depending on the location, with outer suburban areas generally having more chill hours than inner-city areas.
When planning your hazelnut grove, it is advisable to choose a relatively sheltered site, as hazelnut trees do not tolerate strong winds or hot, dry winds. A windbreak may be necessary and should be established two to three years before planting the grove.

Flowering and pollination
All varieties of hazelnuts require cross-pollination to produce nuts, so every planting requires several compatible varieties. Nurseries should be able to advise on compatible varieties, and the hazelnut growers' handbook has an extensive listing of suitable combinations and analysis of varieties to choose from. Successful pollination requires genetic compatibility, as well as suitable flowering and pollen release times. Ennis, Barcelona, Lewis, and Casina are examples of compatible polliniser varieties. Ennis is a later and heavier yielder compared to Barcelona and produces a larger nut suitable for both in-shell and out-of-shell production. Lewis produces a medium nut, while Casina produces a small nut.
Hazelnuts need to have chill hours over the winter to ensure nut set, so cool climates similar to Orange in New South Wales, Myrtleford in Victoria, and Tasmania are suitable. Hazelnut trees should be in commercial production when they are about 6 years old, and a well-managed orchard should remain active for 40 years or more. The nuts mature during the summer months (turning in colour from green to hazel) and are harvested in late summer and early autumn when the nuts fall to the ground within a short period.
The nuts are picked up by hand or harvested mechanically, washed, dried, and sorted by size. A sunny aspect should be chosen to allow complete photosynthesis and production of starches and sugars for the nut crop. Irrigation is beneficial when establishing an orchard to obtain large trees more rapidly. Later, its main use is ensuring adequate soil moisture during the nut-filling stage (December through February) and it is, therefore, very important that they have sufficient soil moisture in the top root zone during this period.

Harvesting
Hazelnuts mature during the summer months, turning from green to hazel, and are harvested in late summer and early autumn. You'll know they're ready when the nuts fall to the ground within a short period. The nuts are then picked up by hand or harvested with a machine, washed, dried, and sorted by size.
Hazelnut trees should be in commercial production when they are about 6 years old, and a well-managed orchard should remain active for 40 years or more. It's worth noting that hazelnuts generally take 7 to 10 years to come into commercial production.
The majority of hazelnuts in Australia are available as rooted suckers or 'whips' that are genetically identical to their parents, ensuring consistency. They are supplied from early July through to late August, and it is recommended to order a year in advance to guarantee supply.
There is a great opportunity for import replacement in Australia, as most of its hazelnut requirements are currently imported, and they are often several months to two years old by the time they reach the country. Freshly harvested hazelnuts are sought after for their superior taste, and there is potential for export to the Northern Hemisphere, where producers could benefit from having a second crop midway through the year.
