Though River Birch is adaptable to a wide range of soils, its ideal soil is kept moist and not wet. Watering deeply at least once weekly is beneficial. Full sun is preferred.
To prolong their lifespan and health and fitness, prune in late summer to fall. Remove branches that rub against each other. Never prune in spring to avoid heavy sap flow and the attraction of egg laying of insects.
