Paper mulberry: complete guide

Overview

The paper mulberry (Broussonetia papyrifera) is a vigorous, fast-growing tree in the Moraceae family, native to India, Korea, and Indochina. Known for robust growth, attractive foliage, and fruit production, this tree has historical significance: its bark was traditionally processed into paper. With an open crown and moderate size, it makes a striking statement in larger gardens.

Appearance and bloom cycle

Paper mulberry grows 33 to 50 feet tall with a full, rounded crown. The leaves are large, rough-textured, and visually striking; young foliage can feel quite coarse. Flowers are inconspicuous, greenish-yellow, appearing in spring (April-May). Following bloom, orange to red fruits appear by July-August, with some cultivars producing edible berries.

Ideal location

This tree thrives in full sun to light shade, requiring at least 6 hours of direct sunlight daily. Avoid deep shade, which promotes tall, spindly growth. Paper mulberry tolerates various urban conditions and wind reasonably well, making it suitable for larger gardens and parks. Provide adequate space for development.

Soil requirements

Paper mulberry is not particular about soil conditions. It grows in standard garden soil with reasonable drainage. Heavy clay can be improved with compost. A pH between 6.0 and 7.5 is ideal. Avoid permanently waterlogged conditions, as this causes root rot.

Watering

Once established, paper mulberry is quite drought-tolerant. Young trees need regular moisture, especially during dry periods. Water deeply but not daily; once weekly typically suffices. In very dry summers, supplemental watering may be needed. Prevent prolonged water saturation.

Pruning

Paper mulberry tolerates pruning well. Prune in early spring (February-March) before growth begins. Remove dead, diseased, or crossing branches. Thinning improves air circulation. Heavy pruning is unnecessary; basic maintenance pruning is usually sufficient.

Maintenance calendar

February-March Conduct pruning. April-May Bloom and young leaf development. June Regular watering during dry spells. July-August Fruit ripening. September-October Autumn color (modest). November-January Dormant period.

Winter hardiness

Paper mulberry is moderately hardy. USDA zones 6-11. In temperate climates (Northern Europe, UK), it grows outdoors but young trees may suffer frost damage in severe winters. Mulch young trees for the first years. In cold regions, wind protection can be beneficial.

Companion plants

Combine with other heat-loving species. Surrounding light-textured plantings like ornamental grasses, bergenia, and smaller hardwoods pair well. Avoid dense underplanting beneath the crown due to shade.
