Hazelnut, also know as Cobnut or Filbert belongs to the Betulaceae family. It is the easiest nut to grow, and the quality of the nuts is high when compared to the other nuts. Hazelnuts are easy to grow since they do not require as much space as the other nut trees.
Hazelnut can grow in almost all types of soils except waterlogged areas. It is preferable to maintain the pH of the ground it grows in, between 5.5 to 7.5. Though hazelnut can survive adverse growing conditions, the roots of the trees must be at least 2.4 to 3 meters deep for optimal growth.
