About the Red Alder
Alders thrive in areas and soils where other plants barely survive. They are very important in land reclamation. Their roots fix nitrogen which will eventually increase the nutrients available for the other plants which follow. These native trees grow quickly to 30-50 ft. high and 20-30 ft. wide. They do well in full sun to part shade in dry to somewhat wet soils. Short lived, making way for more long living plants.
