Crataegus crus-galli

Growth Characteristics

Crataegus crus-galli is a deciduous shrub or small tree belonging to the Rosaceae family, generally growing to a height of 3 to 8 meters. This tree is characterized by thick trunks and somewhat spreading branches, with horn-shaped thorns growing on the branches. The leaves are alternate and oval-shaped, appearing dark green before turning a sooty color in the autumn. White flowers bloom between May and June, and small red berries develop in the autumn.

Propagation Methods

Crataegus crus-galli is primarily propagated by seeds or cuttings. When propagating by seeds, collect the seeds when the fruit ripens in the autumn, subject them to cold treatment during the winter, and sow them in the spring. Cuttings are mainly taken in the summer; newly grown branches are cut off to encourage rooting.

Cultivation Methods

Crataegus crus-galli prefers well-drained soil and thrives in sunny locations. During the first few years, it is important to provide sufficient water to allow the roots to grow fully. Pruning is performed during the winter dormancy period, removing overgrown branches or those damaged by pests or diseases.

Uses in GardensThis tree has high ornamental value, making it ideal for planting in clusters in gardens or parks. It offers a variety of seasonal colors with its beautiful white flowers in spring and red berries in autumn. It is also suitable for use as a hedge or windbreak.

Important Pests and Control MethodsCrust-galli is commonly susceptible to powdery mildew, canker, and scale insects. To prevent these diseases, it is important to perform periodic pruning and maintain good ventilation. While chemical control may be considered in severe cases, the use of natural pesticides is recommended. To prevent pests and diseases, it is important to continuously monitor the condition of healthy trees and detect any infestations early.
