Plant paper birch in early spring or fall in well-drained, acidic soil. Choose a location with full sun to partial shade. Space trees 30-40 feet apart. Water regularly, especially during dry spells, to keep the soil consistently moist. Fertilize in early spring with a balanced, slow-release fertilizer. Prune in late winter to remove dead or crossing branches. Protect young trees from deer and rodents. Monitor for pests and diseases, treating as necessary.
