The spread of the hazelnut tree

Hazelnut trees are particularly widespread in Central Europe. They grow on road and forest edges as well as in mixed forests. They are often planted in the garden as a hazelnut hedge.

Since the tree is very robust, it can withstand extreme temperatures such as those found in Northern Europe or Asia Minor. Hazelnuts are also quite common there in nature.

This is how tall hazelnut trees get

Over time, the trees reach a height of up to six meters. Most hazelnut trees consist of several side branches. A solid single trunk like that of the birch or the beech is very rare.

Hazelnut trees get quite old

Hazelnut trees can be up to 100 years old. From the tenth year you can harvest nuts from the tree.

The bark of the hazelnut tree

The trunks, which can reach a diameter of 18 centimeters, do not form a typical bark. They stay smooth and are light brown in color.

The leaves of the hazelnut

The leaves are round to ovate and light to medium green in color. They reach a length of five to six centimeters. They are very jagged at the edges. The botanist speaks of “sawn” here.

Small hairs form on the underside of the leaf, making the leaves feel velvety.

Hazelnut trees multiply from hazelnuts

Depending on the weather, hazelnut trees start to bloom as early as February. They form yellow kittens that serve as the bees' first food in spring.

Hazelnuts develop from the flowers. Hazelnuts are harvested in autumn, when the nuts have turned brown and fall to the ground.

Hazelnut trees are not self-pollinating. You must always plant at least two trees or shrubs if you want to harvest a lot of hazelnuts.

Hazelnuts in the kitchen

Hazelnuts are particularly valued as a baking ingredient. But hazelnut leaves can also be used in the kitchen. Tea made from the leaves is used in naturopathy for various ailments.

This is how the wood from hazelnut trees is used

The wood can not only be used for the construction of furniture. It is often used for:

  • Wooden fences
  • Tool handles
  • Carvings
  • Walking sticks
  • Wooden furniture
