Manchurian alder is ideally suited to grow in both shade and sun for naturalized woodland gardens. It has a strong central leader and traditionally requires only occasional pruning. If pruning is needed prune in late winter after extreme cold has passed. Prairie Horizon Manchurian alder is also fairly tolerant of urban pollution.
