Family

Moraceae

Plant type

Fruit

Life cycle

Perennial tree

Growth habit

Fast-growing deciduous fruit tree with a broad, spreading canopy

Mature height

Commonly about 20-40 feet, though size varies with cultivar, climate, and pruning

Mature spread

Commonly about 20-35 feet, depending on cultivar and training

Difficulty

Easy

Growing Conditions

Mulberry is listed for full sun conditions. Water needs are listed as moderate; provide consistent moisture during establishment and fruit development while avoiding prolonged waterlogging. The database soil reference is Fertile, well-drained loam or sandy loam with moderate moisture retention. The listed soil pH range is 5.5-7.0, and the listed hardiness range is 4-9.

Hardiness zones

4-9

Sunlight

Full sun

Soil

Fertile, well-drained loam or sandy loam with moderate moisture retention

Soil pH

5.5-7.0

Water needs

Moderate; provide consistent moisture during establishment and fruit development while avoiding prolonged waterlogging

Plant spacing

Allow roughly 20-30 feet between full-size trees, with closer spacing possible for smaller cultivars or regularly pruned plantings

Seed & Germination

For propagation, the database note is mulberry seeds can germinate after a period of moist cold stratification followed by mild to warm growing conditions, but named cultivars are more reliably propagated vegetatively. Planting-depth guidance: For seed propagation, sow stratified mulberry seed shallowly, about 1/4 inch deep, in a moist, well-drained medium. Maturity guidance: Vegetatively propagated mulberries may begin fruiting within a few years, while seed-grown trees generally take longer and may vary from the parent. Use these values as general reference points and adjust for local climate, seed source, and growing conditions.

Germination

Mulberry seeds can germinate after a period of moist cold stratification followed by mild to warm growing conditions, but named cultivars are more reliably propagated vegetatively

Germination temperature

After cold stratification, mulberry seed germination is favored by mild to warm conditions, generally around 65-75°F, with steady moisture

Seed depth

For seed propagation, sow stratified mulberry seed shallowly, about 1/4 inch deep, in a moist, well-drained medium

Sowing method

Seed may be used for seedlings or breeding, while named cultivars are commonly established from rooted cuttings, grafted plants, or layers

Start indoors

Stratified mulberry seeds can be started in containers, but named fruiting cultivars are more commonly established from vegetatively propagated nursery plants

Transplanting

Plant dormant or container-grown mulberries with roots protected from drying, set them at approximately their previous growing depth, and water thoroughly during establishment

Harvest & Propagation

Days to maturity

Vegetatively propagated mulberries may begin fruiting within a few years, while seed-grown trees generally take longer and may vary from the parent

Harvest

Harvest when berries have reached full cultivar color, are soft and juicy, and detach easily; ripe fruit can also be collected by shaking branches over a clean sheet or tarp

Propagation

Mulberries can be propagated from seed, cuttings, layering, or grafting; named cultivars are best maintained vegetatively

Seed saving

Collect seed from fully ripe mulberries, clean away the fruit pulp, dry briefly, and cold-stratify before sowing; seedlings are genetically variable and may not reproduce the parent cultivar

Pollination

Mulberry pollination varies by cultivar and sex expression; many trees are wind-pollinated, and some cultivars can set fruit without a separate pollinizer

Garden Information

Common pests

Scale insects, whiteflies, aphids, mites, thrips, caterpillars, borers, and fruit-feeding birds

Common diseases

Leaf spots, powdery mildew, bacterial blight, cankers, root rots, and other fungal or bacterial diseases

Uses

Fresh fruit, jams, jellies, pies, baking, drying, wine, syrups, smoothies, and wildlife or edible landscapes
