Worth knowing about the hazelnut tree
Hazelnut trees are among the oldest deciduous trees in our latitudes. The nuts of the sturdy tree, which grew 6.000 years before Christ, are not only appreciated by humans, but also by squirrels and other animals.
Hazelnut tree from the birch family
The botanical name of hazelnut, which is also referred to as common hazel, is Corylus avellana. It is a deciduous tree, which often occurs in shrub form.
The tree is hardy and easily tolerates frosts down to minus 30 degrees.
The spread of the hazelnut tree
Hazelnut trees are widespread, especially in Central Europe. They grow on roads and forest edges as well as in mixed forests. In the garden they are often planted as hazelnut hedge.
Since the tree is very robust, it also withstands extreme temperatures, as they prevail in northern Europe or Asia Minor. There too, hazelnuts are quite common in nature.
That's how hazelnut trees grow
Over time, the trees reach a height of up to six meters. Most hazelnut trees consist of several lateral branches. A solid single stem as in the birch or the beech is very rare.
Hazelnut trees are getting quite old
Hazelnut trees can grow 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 have a light brown color.
The leaves of hazelnut
The leaves are roundish to ovate and of light to medium green color. They reach a length of five to six centimeters. At the edges they are strongly jagged. The botanist speaks of "sawn" here.
On the underside of the leaf form small hairs, the leaves feel so velvety.
Hazelnut trees multiply by hazelnuts
Depending on the weather hazelnut trees begin to bloom in February. They form yellow kitten, which serve the bees as the first food in spring.
From the flowers, hazelnuts develop. 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 many hazelnuts.
Hazelnuts in the kitchen
Hazelnuts are especially appreciated as a baking ingredient. But also hazelnut leaves can be used in the kitchen. Tea from the leaves is used in natural medicine for various ailments.
So the wood is used by hazelnut trees
The wood can not be used only for the construction of furniture. It is often used for:
