Alnus × mayrii

Hairy Alder (Alnus × mayrii)

Growth Characteristics

It grows rapidly and thrives in wetlands or along riverbanks. It reaches a height of approximately 10 to 15 meters, and its leaves are oval-shaped with small serrations along the edges. In spring, male and female flowers bloom separately, and the fruit forms small, oval nuts.

Propagation Methods

It is primarily propagated by seeds and cuttings. For seed propagation, mature fruits are collected, dried at room temperature, and sown directly the following spring. For cutting propagation, young branches are cut in spring or autumn and planted as cuttings.

Cultivation Methods

It is a relatively easy plant to cultivate. It grows well in sunny locations or partial shade, and thrives best in soil that retains moisture. Well-drained soil is suitable, and while special fertilizers are not required, applying organic fertilizer in the spring further promotes growth. Uses in Gardens
It plays an important role in soil stabilization, making it useful for riverside landscaping and creating green spaces. Thanks to its rapid growth rate, it is also suitable for creating shade. In gardens, it serves as a tree that provides moderately large shade.

Important Pests and Control Methods

It is a relatively resistant plant to pests and diseases. However, leaf blight or aphid damage may occasionally occur. In the case of leaf blight, immediately remove infected leaves and prune branches to ensure good ventilation. Aphids can be washed away with water pressure or, if necessary, eco-friendly insecticides can be used.

Based on this information, you can properly manage and utilize the hairy alder.
