Years to Production. A newly planted hazelnut tree does not start producing a nut crop until the tree becomes established. A first hazelnut crop can be expected within two to five years of planting the tree.The initial crops are usually small, but as the tree matures, the crops increase in size. A mature hazelnut tree can produce up to 25 pounds of nuts in a single year.Once a tree begins to produce, you can expect a new crop of hazelnuts each year, up to 50 years.ou must grow two hazelnut trees with strong genetic differences, one as a pollinator and the other as a producer to get a nut crop. These trees need to be within about 65 feet of each other for cross pollination to take place.
Most nut trees are planted 25â30 feet apart. Since hazelnuts are more shrub-like, they can be spaced about ten feet apart. Plant bare-root plants in the early spring. Mulch with straw or hay to reduce weeds and conserve soil moisture.
