Brief Description: Vigorous, fast growing tree found as either single or multi-stemmed. Rounded crown shape with single stem, more irregular when multi-stem. Attractive exfoliating bark provides winter interest.

Possible Problems: River birches are Missouri natives that are naturally adapted to the climate and are extremely resistant to birch borer. River birches have some susceptibility to aphids, leaf miner and iron chlorosis in high pH soils. River birches often drop leaves during the summer in hot, dry conditions but this is usually not harmful to the tree. Small twigs and branches often shed, creating litter problems.
