The irrigation of the hazelnut tree

The hazel needs regular watering only if there is a prolonged period of drought; if, on the contrary, the precipitations are frequent, especially during the winter season, the irrigation must be interrupted. It is essential to avoid water stagnation, which can cause root rot or fungal diseases that are dangerous for the plant. The younger specimens, however, have a greater need for water than the adult ones, and consequently they must be bathed more consistently. Drip irrigation is recommended as an irrigation method: through the use of drippers, water resources can be administered moderately and sparingly in the form of thin jets, wetting the surface of the soil or directly the roots.

Growing tips


The soil recommended for the hazel is well-drained and well-drained, poor in clay and limestone. Before planting, it is important to work the soil, so as to make it softer and eradicate weeds: a preliminary fertilization operation is also suggested to ensure optimal development of the plant. Planting must be carried out in autumn or winter, in a hole about half a meter deep, and followed by mulching the soil with organic materials. Pruning, to be carried out from the second year onwards, is essential to eliminate old branches and make new ones grow; it is essential to use, immediately after, a specific mastic for the healing of cuts. The branches that, developing inwards, obstruct the supply of light must also be removed.

Fertilization


The preliminary fertilization of the soil, completed before the planting, involves the use of organic substances, such as manure or mature manure; subsequently, to better favor the development of the plant, these products can be integrated with fertilizers containing the three macro elements, namely potassium, phosphorus and nitrogen. The latter is aimed at ensuring a vigorous growth of the vegetative parts, while potassium and phosphorus respectively ensure an improvement in the quality of the fruit and a strengthening of the root system. Fertilization must take place twice a year, in spring and autumn; in the autumn period you can also use only natural fertilizers,

Core: Exposure, pests and diseases


The exposure must take place in a sunny place or at most in partial shade; the important thing is that there are no too strong winds and that the temperatures are not excessively low, as these conditions would damage the crop. Among the parasites that can affect this plant we must remember the eriophid, which attacks the buds causing them to dry out and which requires sulfur-based products for its elimination; harmful is also the green or brown bug, which can cause the atrophy of the hazelnuts under the shell and is fought by means of special insecticides. Among the most annoying fungal diseases, on the other hand, there is powdery mildew, which manifests itself as whitish mold and causes necrosis of the leaves and deterioration of the fruits and, in general, of the tree;
