Large hazelnut trees can and should be pruned in autumn. This is not only beneficial to the accumulation and storage of nutrients in the hazelnut tree, but also helps to keep the orchard clean and tidy and ensure the quality of the hazelnuts. After harvesting, the plant enters the adjustment and pruning period. In late autumn, when all the leaves have fallen, pruning can be carried out. Pruning of large hazelnut trees in autumn mainly involves thinning and shaping branches.
Can large hazelnut trees be pruned in autumn
Large hazelnut trees can be pruned in autumn, and they should be pruned.
Hazelnut tree, also known as mountain chestnut tree and pointed chestnut tree. It is a deciduous shrub of the genus Corylus in the Betulaceae family. The fruit is nearly spherical or oval, with a hard and smooth skin, and is known as "hazelnut". Together with walnuts, almonds and cashews, it is also known as the "four major dried fruits" in the world.
Hazelnuts mature and are harvested from September to October every year. After harvesting, the plant enters the adjustment and pruning period. In late autumn, when all the leaves have fallen, pruning can be carried out. Pruning of large hazelnut trees in autumn mainly involves thinning and shaping branches.
1. Thinning branches
When pruning large hazelnut trees, diseased and dead branches should be cut off first; then thin, cross branches and duplicate and overlong branches should be cut off; finally Cut off inner branches and branches that are inconsistent with the growth of the tree.
In this way, the branches can be kept neat, clean and sparse, and it is also conducive to the accumulation and storage of nutrients in the tree body, and is more conducive to the growth of branches and leaves in the coming year, lighting and ventilation.
2. Shaping
Plastic shaping refers to a certain shape that is pruned according to the tree's strength when pruning the branches of the tree. That is what we often call tree shape. Because it is impossible for any orchard to allow every branch to grow in a disorderly manner and the tree shape to be messy.
The tree shape of large hazelnut trees is usually divided into trunkless cluster tree shape and single-stem happy tree shape. The two tree shapes differ slightly in pruning and shaping.
①Stemless clump-like tree shape
The clump-like tree shape is usually supported by several main branches. Therefore, when pruning, in addition to cutting off the diseased and weak branches on a few main branches , dry dead branches and bottom side branches.
We should also cut off scattered and overly long branches on the periphery to make the tree look slightly gathered. As a result, the orchard is more transparent and less pests and diseases occur.
②Single-stem happy tree shape
Single-stem happy tree shape refers to a tree shape supported by one main trunk and with a dispersed crown. When pruning this type of tree, the branches are usually spread out as much as possible and the crown is shaped.
That is to say, during autumn pruning, try to cut off diseased, weak and dry branches on the fruiting branches, and at the same time cut off thin, crossing and overlapping branches, so that the leaves and branches can receive even light and maintain good ventilation.
Summary
Large hazelnut trees can and should be pruned in autumn. This is not only beneficial to the accumulation and storage of nutrients in the hazelnut tree, but also helps to keep the orchard clean and tidy and ensure the quality of the hazelnuts.
If the large-fruited hazelnut tree is slightly pruned, it can be pruned at any time. If it is a large-scale pruning, it is best to do it in winter or spring.
