Unlike other fruiting trees, the hazelnut tree blooms and pollinates in the middle of winter. Wind carries the pollen from catkins (male flowers) to small red female flowers, where pollination occurs. The flowers remain inactive until spring, when fertilisation completes and the nuts begin to develop.The natural growth habit of the hazelnut is a bush, or multi-stemmed small tree as found in Turkey and Southern Europe. In the US, hazelnut trees are grown as single trunk trees that can grow to 5 metres or more.All varieties of hazelnuts require cross-pollination in order to produce nuts, so every planting requires two or more varieties.ost of a hazelnut trees roots are found in the first meter of soil, and hazelnut trees draw moisture primarily from the upper soil layer. But soils must be sufficiently deep to allow active root system penetration two to three metres to provide the structural strength to resist wind damage.
