Product Description

Alnus glutinosa, commonly known as the Common Alder or Black Alder, is a versatile deciduous tree native to Europe and parts of Asia. This tree is valued for its ecological significance and adaptability to various growing conditions.

The Common Alder is a medium-sized tree that typically reaches heights of 50 to 80 feet (15 to 25 meters). It features a conical to oval-shaped canopy and distinctive glossy, dark green leaves with serrated edges. In the early spring, it produces slender, cylindrical male and female catkins that dangle from the branches before the leaves emerge. Female catkins mature into small cone-like structures that contain tiny seeds. Alnus glutinosa is also known for its ability to thrive in wet or waterlogged soils, making it a valuable tree for riparian zones and wetland habitats.


  1. Location: Plant the Common Alder in a location that receives full sun to partial shade. It can tolerate a range of soil types, including wet or poorly drained soils, which makes it suitable for areas with periodic flooding.

  2. Soil: While Alnus glutinosa is well-adapted to wet soils, it can also grow in loamy or sandy soils. It is relatively adaptable to soil pH variations, including slightly acidic to slightly alkaline conditions.

  3. Watering: Adequate moisture is crucial during the tree's establishment period. Once established, it can tolerate periodic flooding or waterlogged conditions without issues. Regular watering may be necessary during extended dry spells.

  4. Pruning: Minimal pruning is typically required for the Common Alder. You can remove dead or diseased branches and shape the tree as needed during the dormant season.

  5. Fertilization: In most cases, mature Alnus glutinosa trees do not require fertilization. However, in very poor soils, you can provide a balanced, slow-release fertilizer in the spring to encourage healthy growth.

  6. Mulching: Apply a layer of organic mulch around the base of the tree to conserve soil moisture, regulate soil temperature, and suppress weeds. Avoid piling mulch against the trunk.

  7. Pests and Diseases: Common Alder is relatively resistant to pests and diseases. However, it can occasionally be affected by aphids, which can be controlled with appropriate insecticidal measures if necessary.

  8. Wildlife Value: This tree is a valuable habitat for wildlife, attracting various bird species with its seeds and providing cover and nesting sites.

Alnus glutinosa is a valuable tree for its adaptability to wet conditions and its ecological role in improving soil fertility. It is often used in reforestation projects and restoration of riparian areas. With proper care, it can thrive in a variety of landscapes, enhancing both environmental and aesthetic aspects of your outdoor space.
