Hazelnut cultivation begins with sowing in spring. Plants need a sunny location and well-drained soil. Hazelnuts are undemanding plants and can grow in a variety of soils. As they grow, the plants need regular watering and fertilizing. It is also important to remove weeds and protect the plants from pests and diseases. In autumn, when the nuts are ripe, they are harvested from the trees and freed from the green husk. Hazelnuts can be grown in monocultures as well as in mixed crops with other crops such as fruit trees. In recent years, there has been an increasing trend toward agroforestry, i.e., the planting of trees and shrubs on agricultural land that can help improve soil quality and biodiversity.
