Alnus glutinosa, commonly known as the black alder or European alder, is a tree native to most of Europe and southwest Asia. It thrives in temperate climates and is often found in wetlands, riverbanks, and other moist environments. The tree is known for its ability to improve soil fertility through nitrogen fixation. It has a dormancy period during the winter months.

Care Instructions
To care for Alnus glutinosa, provide it with plenty of direct sunlight and ensure it receives moderate temperatures. The tree prefers environments with moderate humidity. Regular watering is essential to keep the soil evenly moist, especially during dry periods.Soil
Alnus glutinosa prefers loamy soil that is well-draining yet retains moisture. The soil should be slightly acidic to neutral in pH. It can tolerate a range of soil types but thrives best in nutrient-rich, moist conditions.Fertilizer
This tree generally does not require additional fertilization due to its ability to fix nitrogen. However, if the soil is particularly poor, a balanced fertilizer can be applied sparingly.Repotting
As a tree, Alnus glutinosa is not typically repotted. Instead, ensure it is planted in a suitable outdoor location where it has ample space to grow and develop its root system.Propagation
Alnus glutinosa can be propagated through seeds or cuttings. Seeds should be sown in the fall, while cuttings can be taken in late winter or early spring. Ensure the cuttings are kept moist until they establish roots.Pruning
Pruning is beneficial for Alnus glutinosa to maintain its shape and remove any dead or diseased branches. Prune during the dormant season, typically in late winter, to encourage healthy growth.Toxicity
Alnus glutinosa is not known to be toxic to pets or humans. It is generally considered safe to have in gardens and landscapes.Additional
Alnus glutinosa is valued for its ecological benefits, including erosion control and habitat provision for wildlife. It is also used in land reclamation projects due to its ability to improve soil quality.REVOLUTIONIZE YOUR PLANT CARE
