Hazelnuts are one of the easiest nuts to grown. On top of that, they produce quickly, so you don’t have to wait a decade for your first harvest. Hazelnuts can handle anything from loamy to clay soil, but don’t do well in peaty or wet areas. Avoid overly rich soil because it will cause the tree to leaf at the expense of fruit. When growing hazelnuts, they can handle a little shade, especially in hot and dry areas. They need at least 4 hours of direct sunlight a day to produce well. The shadier the spot, the fewer fruits the tree will produce.
