River Birch Tree Overview
River Birch tree (Betula nigra) is a medium sized deciduous tree, typically growing 30 to 40 ft tall. With an attractive bark that is salmon pink to red-brown in color it’s a sight to behold as it peels or scales to reveal the inner bark. River Birch tree is a great choice as an ornamental tree as it can be planted in many different climates and soil conditions across North America. It is tolerant of different soil types, but grows especially well in wet sites. It is typically used to help reduce stream bank erosion.
A few of the great benefits of the River Birch include its resistance to the bronze birch borer and fast growth. For fast growth, you can fertilize young trees in late winter before new growth begins. Prune the trees only during summer to avoid bleeding, which happens when the cut is done during the sap flowing. You can use the sap to make birch beer and vinegar.
