Thewotis among the oldest plant species existing on Earth, just think that its ancestors were discovered in stratifications dating back to the geological era of the Miocene, from 23 to 5 million years ago.
The tree ofwotis characterized by a majestic extension, so hiscultivationit is linked to ornamental purposes (for the expanded and globose foliage), for the production ofnutsor for the production of wood (for the majestic trunk and the quality of the timber).
The walnut is a typical plant of temperate climates, it can vegetate and produce well up to 800-1000 meters above sea level. It resists winter cold but fears late frosts: if during flowering (April - May) the temperature drops to -2 ° C, there could be damage to the crop. Almost all walnut varieties are self-fertile and pollination occurs by the wind since this plant does not attract many insects.
In summer it tolerates high temperatures well (as long as they are not higher than 38 ° C) and expresses all its potential ifcultivationit is implemented in hilly areas or in the southern plains in open environments.
How to grow walnuts
Thewotit prefers medium-textured and loose, deep and fresh soils, especially rich in organic matter. It hates waterlogging and does not produce well in dry soils. The optimal pH is between 5 and 7.
The planting is carried out in winter and to ensure good qualitative and quantitative yield, it is recommended to provide periodic fertilization. The most suitable fertilizers are high in potassium and nitrogen with minimal quantities of zinc, manganese and boron.
In the first three years after planting it is possible to cultivate at the foot of the wot other plants (such as soybeans), while from the fourth year it is recommended to cultivate a turf that, especially in the home, manages to enhance the wot and to simplify the collection phases.
In starting awalnut cultivation, pay close attention to choosing the most suitable variety for your territory. To orient yourself, we recommend that you consult the article "Nuts, varieties“.
Diseases of the Walnut
It will be necessary to protect the walnut from bacterial diseases such as Xantomonasand fungal diseases such as Brown Apical Necrosis caused by Gusarium spe, Alternaria sp and Anthracnose. For this purpose it is recommended to proceed with 2-3 treatments based on cupric products mixed with Mancozeb and with products based on Tebuconazole. Among the insects that threaten the cultivation of walnut is the Carpocapsa, for its control it is advisable to proceed with 2-4 interventions in the first generation and 2-3 in the second generation. Overall, therefore, between 8 and 12 treatments are required in a crop cycle.
