Characteristics of sea alder
Sea alder is a medium sized tree that can reach up to ten meters in height. Its oval leaves have serrated edges, are dark green, and present a smooth surface. In autumn the leaves turn yellow and golden, creating a visual display that enhances the landscape.
The bark is smooth and grayish to brown, becoming rougher and cracked with time. The tree also bears small elongated catkins that add to its decorative appeal.
Habitat and growing conditions
Sea alder favors moist areas such as riverbanks, estuaries, and marshes. It tolerates acidic, wet soils and can cope with salinity or excess water better than many other trees. Although its origin is North America, it has been introduced to other parts of the world because of its protective and ornamental qualities.
How to care for plants in autumn: basic guide and tips
Sea alder plays a fundamental role in plant protection, especially in areas prone to flooding or high salinity. Its roots form a symbiosis with nitrogen fixing bacteria, enriching the soil and creating a healthy environment for neighboring crops. Its tolerance of saline soils helps protect indoor plants by acting as a natural barrier against salt intrusion.
This tree also helps prevent soil erosion. Its roots anchor in wet or flooded areas, strengthening the soil and keeping it from washing away. It acts as a natural windbreak as well, shielding small plants from strong winds and storms.
