American hazelnut grows in acidic, alkaline, silty, moist, rich, sandy, well-drained and clay soils. The type of soil series is an important factor to consider when deciding where to plant a hazelnut orchard. Trees that grow in deep, medium-textured lowlands are larger and more productive than trees that grow in shallow, sandy or high-clay soils. Hazel trees do not tolerate damp soils during the active growing season.
However, their roots are shallower than those of most fruit trees. Because waterlogged soils dry from top to bottom, the root zone of hazelnuts dries out faster than that of trees with deeper roots. Like most nut trees, hazelnuts require deep, well-drained soil. They will not tolerate waterlogged soil and, as a result, will develop root rot.
. Heavy soils can be improved by incorporating gypsum and organic matter and piling up the soil before planting to improve drainage. In Utah, hazelnuts that are grown for nut production are generally kept as shrubs, with an oval or round shape that grows to 15 feet tall and wide. Hazelnuts thrive in well-drained, clay soil, but they grow in many types of soil as long as the soil is well-drained.
Nut production is better when cross-pollination occurs with another variety of the same species (see Table 1) or with other plants of the same species cultivated with seeds. Hazelnuts are susceptible to a number of diseases, but many of them are less common or not present in the intermountain west. In spring, hazelnuts grow and during this season the buying and selling of the product reaches its peak and farmers sell to factories. In case you're not already familiar, filbert is an old name for the hazelnut that's still commonly used in the Northwest.
Hazelnuts are somewhat susceptible to a number of pests, such as aphids, leaf rollers, insects that feed on leaves and nuts, mites and scales. If a potential pest is found, agriculture or horticulture agents at the local USU Extension office can help you identify and control. Hazelnut kernels are highly profitable in the country's trade, import and export and cause the country's economic prosperity. Hazelnuts prefer well-drained soil with few nutrients; soil that is too rich produces abundant leaf growth at the expense of flowers and nuts.
Hazel trees are usually full of roots, and sometimes root shoots come out to the surface of the soil. Hazelnut is a unique and delicious product and an oil that everyone is in favor of and is very useful for humans. Hazelnuts can be rich in properties besides their good taste, and their consumption is also rich in protein. All hazelnut species benefit from being planted in frost-protected areas to increase the likelihood of consistent nut production.
Hazel trees can withstand a fairly high water table in March if the water table falls in April and if ground water below 4 feet (1.2 meters) drains freely. While most of the roots of a hazel tree are found in the first 2 feet (0.6 meters) of the ground, adequate soils allow trees to develop active root systems at depths of 6 to 10 feet (1.8 to 3 meters). Referring to soil maps is the first step in determining the suitability of a site for hazelnut production. Hazelnuts are wind-pollinated and require another hazelnut tree, of a compatible variety, to be planted nearby for effective pollination.
