Mulberry Tree: How to Plant, Grow, and Buy the Morus Mulberry

The mulberry is a genus of fast-growing, prolifically fruiting trees in the Moraceae family, reaching 20 metres or more in height and prized for both its sweet berries and its dense shade. Belonging to the genus Morus within the order Rosales, mulberries are grown across temperate and subtropical regions of North America, Europe, China, Korea, South Asia, Australia and Brazil, and they were long ago carried into new territories both by human cultivation and by the birds and animals that feast on their fruit.

What is a mulberry (tutovoe) tree?

A mulberry tree is a deciduous member of the Morus genus, valued as a shade tree, an ornamental, and a heavy-cropping fruit tree. Unlike the common apricot, which is planted only by people, the mulberry spreads through woodlands with the active help of birds and other creatures of the forests and fields — the fruit is a favourite treat of birds and rodents alike. The genus sits in the mulberry family Moraceae, alongside relatives such as Broussonetia papyrifera (paper mulberry) and the Osage orange, and includes three species most commonly grown in gardens: white mulberry (Morus alba), red mulberry (Morus rubra), and black mulberry (Morus nigra).

Mulberries carry a long cultural history that reaches well beyond the garden. Morus alba is native to China, where it has been cultivated for millennia as the sole food source for the silkworm (Bombyx mori) at the heart of the silk industry. In North America, Morus rubra is native to the Eastern United States, and Indigenous peoples including the Cherokee, Iroquois, Seminole, Timucua and Muskogee Indians ate the fruit and used the tree; early accounts from the expedition of De Soto in Florida describe mulberries, and Roman sources record the fondness of Emperor Elagabalus for the berries.

Botanical description of the tree

The mulberry is a medium-to-large deciduous tree with a broad, spreading crown, distinctive heart-shaped leaves and soft, elongated aggregate fruits that resemble a slender blackberry. Its leaves are notably polymorphic — even on a single tree, some are simple and heart-shaped while others are deeply lobed with two, three or more divisions. Leaf surface texture helps separate the species: the leaves of Morus alba tend to be smooth and glossy, while those of Morus rubra are larger and rough or sandpapery on the upper surface. Mulberries can be monoecious or dioecious depending on species and cultivar, so some trees carry both male and female flowers while others are strictly male or female; wind-pollinated catkins produce the flowers, and many named cultivars are self-fertile.

Bark appearance and how it changes with age

Mulberry bark begins smooth and greyish-brown on young trees, then develops shallow ridges and furrows as the tree matures, eventually becoming rugged and scaly with an orange-brown tint visible in the fissures. Young twigs are slender and can be finely hairy, bearing small pointed winter buds pressed close to the stem. This gradual roughening of the bark, combined with the low-branching, broad-crowned habit, makes an old mulberry easy to recognise in winter even without leaves or fruit.

Height, crown and lifespan

Mulberry trees commonly grow to 20 metres or more, with white mulberry among the fastest-growing shade trees for temperate locations and black mulberry staying smaller and more shrub-like. In June and July, when the berries ripen, the trees are literally studded with birds: starlings peck the fruit at the very tops while nimble sparrows and other birds feed lower down. The tree loves plenty of light, so it grows along roadsides and at the edges of woodland. Black mulberry (Morus nigra) is famously long-lived, with specimens surviving for hundreds of years, while white and red mulberries are more moderate in longevity but still make durable, decades-long garden trees.

Mulberry varieties and cultivars

Growers can choose from dozens of named mulberry cultivars bred for flavour, size, cold hardiness or ornamental form. Nurseries such as Fast Growing Trees, Chestnut Hill and the Grimo Nut Nursery in Ontario offer a wide catalogue, and specialists like Linda Grimo and Steven Biggs have helped popularise hardy selections. Popular fruiting cultivars include Illinois Everbearing Mulberry, Pakistan mulberry (also sold as Pakistan Fruiting Mulberry, Pakistan White Fruiting Mulberry and King White Pakistan), Black Beauty Fruiting Mulberry, Silk Hope Mulberry, Kokuso Korean Mulberry, Oscar Mulberry, Wellington Mulberry, Shangri La Mulberry, Tehama, Early Bird Mulberry, Beautiful Day mulberry, Sweet Lavender mulberry and Red ShahToot Mulberry. Cold-hardy white selections such as Nikita White Mulberry, trialled at the Nikita Botanic Garden, and material tested at the New York State Fruit Testing Center in Geneva extend the range into colder gardens.

White, black and red mulberry

The three main mulberry species differ mainly in fruit colour, flavour and cold tolerance. White mulberry (Morus alba), the White Mulberry of the silk trade, bears white, pink or lavender berries that are very sweet and mild, and it is the hardiest, tolerating USDA zone 4. Black mulberry (Morus nigra) produces the darkest, most intensely flavoured berries with a rich sweet-tart balance, but is the least cold-hardy. Red mulberry (Morus rubra), the Native Red Mulberry of North America, yields deep red to near-black fruit with a well-balanced flavour and offers strong native-plant and ecological value for wildlife restoration.

Ornamental forms add further choice. The Weeping Mulberry and Contorted Mulberry are grown chiefly for their sculptural, cascading or twisted branch structure rather than heavy fruiting, making them landscape features in the American landscape industry. Non-staining or nearly seedless white-fruited types — Ivory White Mulberry, Nikita White Mulberry and White Fruiting Mulberry among them — appeal to gardeners who want the fruit without the mess of dark juice.

Dwarf varieties for small spaces

Dwarf and bush mulberries let gardeners with limited space grow fruit in containers or tight beds. Compact selections such as the Dwarf Mulberry, the Everbearing Mulberry Bush and the MojoBerry® Mulberry Bush stay small enough for patios and small yards while still producing a steady crop through the season. These bush forms can also be trained into a single-stemmed tree shape over time, giving flexibility in how they fit a garden design.

Berries: size and ripening times

Mulberry berries are elongated aggregate fruits, typically 2–5 centimetres long, that ripen progressively rather than all at once. A distinctive feature of the mulberry is that it does not fruit all at once like the apricot, but gradually over weeks. The colour develops through the season from green to red or lavender and finally to the deep, fully ripe shade, so a single tree can carry unripe and ripe fruit at the same time. This staggered maturation, running roughly from June through August, means fresh berries are available over a long harvest window.

Yield of a single tree

A large mature mulberry can be extraordinarily productive over a long picking season. The mulberry harvest lasts 2 to 2.5 months, and over that time a single large tree can yield 200 to 250 kilograms of berries. The fruit contains a large amount of sugar, organic acids, vitamins and microelements. Because ripe berries drop readily and stain hard surfaces, many growers spread sheets or netting beneath the canopy to catch the crop and reduce mess on paths and patios.

Growing and caring for mulberry

Mulberries are among the easiest fruit trees to grow, adapting to a wide range of soils and climates with minimal fuss once established. Propagation is possible from seed, from hardwood or softwood cuttings, and by grafting desirable cultivars onto seedling rootstocks — grafting and cuttings are preferred where a named variety's fruit quality must be preserved. Plant in autumn or early spring, water regularly through the first two seasons, and give the tree room for its broad crown to develop.

Light and soil requirements

Mulberries need full sun and tolerate a broad range of soils, from sandy to clay, provided drainage is reasonable. The tree loves plenty of light, so in the wild it grows along roadsides and at the forest edge, and in the garden it fruits best in an open, sunny position. Mulberries accept a wide pH range and cope with poorer soils better than most fruit trees, which also makes them useful for erosion control on slopes and disturbed ground.

Preferred environmental conditions

Mulberries thrive in warm, sunny sites with good air movement and adapt readily to different regional climates. They handle urban conditions, coastal exposure and a range of humidity levels, which is why they are found growing well from Texas and California to Florida in the United States and across Europe and Australia. Choosing a site away from patios, driveways and walkways is wise, since dropped fruit stains paving.

Cold hardiness and temperature tolerance

Cold tolerance varies sharply by species, with white mulberry the toughest and black mulberry the most tender. White mulberry and hardy cultivars such as Illinois Everbearing and Nikita White can be grown down to USDA zone 4, making them suitable for cold-climate gardens, while Morus nigra needs a milder, more sheltered site. For gardeners in cold regions, selecting a proven cold-hardy cultivar is the single most important decision.

Drought tolerance

Established mulberries are notably drought-tolerant, drawing on deep root systems to survive dry spells once they are settled in. Young trees still need consistent watering through their first two summers to build those roots, but mature specimens rarely require irrigation except in prolonged drought. This resilience makes mulberry a dependable choice for low-maintenance and water-wise plantings.

Annual pruning and upkeep

Mulberries need only light annual pruning to keep a strong, open framework and manageable size. Prune in late winter while dormant, removing dead, crossing or crowded branches, and always cut with sharp, clean tools for safety and clean healing. Formative pruning in the first few years establishes a good structure, and traditional techniques such as pollarding and coppicing can hold a tree to a compact size or produce fresh leafy growth — coppicing cuts the tree back near ground level, while pollarding cuts to a higher permanent framework. A light feed in spring supports steady growth, though mulberries seldom need heavy fertilising.

Mulberry diseases and pests

Mulberries are hardy and largely trouble-free, with good disease resistance compared with most fruit trees. The main disorders to watch for are fungal leaf spots and the growth abnormality known as witches' broom, a dense proliferation of shoots caused by disease; good airflow and prompt pruning of affected wood keep problems in check. Overall pest and disease susceptibility is low, which is a major reason mulberry suits sustainable, low-input gardens.

Birds and protective netting

The single biggest challenge in harvesting mulberries is competition from birds, which flock to the ripening fruit. When the berries ripen the trees are covered with birds — starlings feed at the treetops while sparrows and others feed lower down — and this wildlife appeal, while ecologically valuable, means a share of the crop is lost to them. Draping bird netting over smaller trees or bushes during the ripening window is the most effective way to protect the harvest, while larger trees usually produce enough to share.

Culinary uses of mulberry fruit

Mulberry berries are eaten fresh and used in a wide range of cooked and preserved foods. Sweet, juicy and mild, they work in baking, desserts, smoothies, wine and dried-fruit snacks, and their high sugar content makes them excellent for preserving. Because the dark juice stains fingers, clothing and surfaces, cooks often handle the fruit over easily cleaned surfaces and wear gloves when processing large quantities.

Compotes, jam, juice and jelly

Mulberries are made into compotes, jam, juice, jelly and marmalade. Their natural sweetness and organic acids give preserves good flavour, though many recipes add lemon juice or pectin to balance the mild acidity and help jams and jellies set. The berries freeze well too, letting the long summer harvest be enjoyed year-round.

Health benefits and uses

Mulberry fruit is rich in sugars, organic acids, vitamins and microelements, giving it a place in both diet and traditional medicine. The berries have long featured in folk medicine across their range, and the leaves and fruit are used today in various health preparations. As with any fruit, mulberries are best enjoyed in moderation as part of a varied diet.

Effect on the heart and blood pressure

There is a long-held belief that eating fresh mulberries on an empty stomach stimulates the work of the heart and helps regulate blood pressure. This is a traditional folk-medicine view rather than a substitute for medical advice, but it reflects the fruit's enduring reputation as a wholesome, nourishing food.

Use as a dietary supplement

Mulberry leaves and fruit are also processed into dietary supplements, sold as powders, teas and extracts. White mulberry leaf in particular is a common supplement ingredient. Anyone using such products should treat them as supplements to, not replacements for, a balanced diet and should follow reputable guidance on dosage.

Agricultural and fodder uses

Beyond fruit, mulberry is a valuable agricultural and fodder plant, most famously as the food source for silkworms. The leaves of Morus alba feed the silkworm Bombyx mori, the foundation of the silk industry in China and across Asia, and the same nutritious foliage serves as fodder for livestock. Fast regrowth after pollarding or coppicing makes mulberry an efficient source of repeated leaf harvests for animal feed.

Benefits of growing mulberry in the garden

A mulberry earns its place in the garden as a fast-growing shade tree, a heavy fruit producer and a magnet for wildlife. It supports birds and pollinators, fits well into permaculture and food-forest designs, and provides dependable summer harvests with little maintenance. Its adaptability, drought tolerance and disease resistance make it one of the most rewarding trees for sustainable home agriculture.

Companion berry crops and alternatives

Mulberry pairs well with other easy fruit trees and provides good alternatives for gardeners wanting variety. Complementary choices for a food forest include the American Paw Paw Tree, the Chicago Hardy Fig Tree, and native trees such as Hackberry, Sassafras and the Osage orange for shade and wildlife value. Grouping mulberries with these companions extends the harvest season, broadens flavours and strengthens the ecological function of the garden.
