1. Basic Identification

Common Name: Standard Mulberry Tree
Botanical Name: Morus nigra
Former Name: Not applicable
Plant Type: Fruiting Deciduous Tree
Plant Code / SKU: PLT-1715
Alternative Names:
Black Mulberry
Persian Mulberry
Toot Tree
توت (Arabic)

2. Taxonomy & Classification

Order: Rosales
Family: Moraceae
Genus: Morus

3. Origin & Distribution

Native to the mountainous regions of southwestern Asia, likely Iran and Afghanistan. It has been cultivated for thousands of years and is now widely naturalized across Southern Europe, the Middle East, and other temperate regions worldwide.

4. Visual Characteristics

Leaves: Large, heart-shaped (cordate) leaves with serrated edges. They are dark green, with a rough texture on top and a paler, downy underside.
Flowers: Inconspicuous, small, greenish flowers that grow in dense clusters called catkins, appearing in spring.
Fruit: The fruit is a collection of small drupes that form a single, bumpy berry. It transitions from white/green to red, and finally to a deep, dark purple-black when fully ripe.
Stem/Trunk: The bark is rugged, gnarled, and grayish-brown, becoming more fissured with age. In its 'Standard' form, it is trained to have a single, straight trunk topped by a rounded canopy.

5. Size & Dimensions

Mature Height: Typically 10-12 meters (30-40 feet), but can be kept smaller with pruning, especially in containers.
Mature Spread: 10-15 meters (30-50 feet), forming a broad, rounded crown.
Growth Rate: Slow to moderate.

6. Light Requirements

Prefers full sun, requiring at least 6-8 hours of direct sunlight per day for the best growth and fruit production. It can tolerate partial shade, but fruiting may be reduced.

7. Watering Needs

Young trees require consistent moisture to establish a strong root system. Once established, Morus nigra is quite drought-tolerant. Water deeply but infrequently, allowing the top soil to dry out between waterings. Container-grown plants will require more frequent watering, especially during hot weather.

8. Soil & Potting

Soil Type: Adaptable to a wide range of soils but thrives in deep, fertile, well-drained loam. It can tolerate clay, sandy, and chalky soils.
Soil pH: Tolerant of a range from slightly acidic to alkaline (pH 6.0 to 8.5).
Potting: For container growing, use a large pot with excellent drainage holes and a high-quality, well-aerated potting mix. Repot every 2-3 years or when it becomes root-bound.

9. Temperature & Humidity

Hardiness Zones: Hardy in USDA Zones 5-9. It requires a period of winter chill to set fruit properly.
Temperature: It is tolerant of both frost and heat once established.
Humidity: Adapts well to a wide range of humidity levels.

10. Fertilization

Feed in early spring with a balanced, slow-release fertilizer, such as one formulated for fruit trees. Avoid high-nitrogen fertilizers, which can encourage excessive leaf growth at the expense of fruit production. An annual top-dressing of compost or well-rotted manure is also beneficial.

11. Maintenance & Care Level

Care Level: Low. It is a hardy and resilient tree that requires minimal intervention once established.
Pruning: Prune during the dormant season (late winter) to maintain shape, remove any dead, diseased, or crossing branches, and encourage an open structure for good air circulation. For the 'Standard' form, regular pruning is needed to maintain the clear stem and rounded head.
Pest/Disease: Generally resistant but can be susceptible to canker, leaf spot, powdery mildew, and scale insects. Birds are highly attracted to the ripe fruit.

12. Growth & Propagation

Growth Habit: A deciduous tree that naturally develops a short trunk and a wide-spreading, gnarled crown. The 'Standard' form is trained for a more formal, sculptural appearance.
Propagation: Best propagated from semi-hardwood or hardwood cuttings. It can also be grown from seed, although the resulting tree may not be true to the parent variety. Grafting is also a common method for commercial production.

13. Common Problems

Fruit Staining: The dark, juicy berries can stain patios, walkways, cars, and clothing. It's best to plant it away from these surfaces.
Root System: The root system can be extensive and vigorous. Plant well away from foundations, septic systems, and underground pipes.
Fruit Drop: The tree can drop a significant amount of fruit, which can be messy if not harvested.

14. Benefits & Uses

Culinary: Highly prized for its sweet, flavorful fruit, which is eaten fresh or used to make jams, jellies, pies, tarts, wine, and cordials.
Ornamental: A beautiful specimen tree, valued for its gnarled character, lush foliage, and ability to provide dense shade. The 'Standard' form makes an excellent formal accent in gardens, patios, or large containers.
Wildlife: The fruit is a valuable food source for birds and other wildlife.

15. Toxicity & Safety

Human: The ripe berries are edible and safe for consumption. However, unripe fruit and the milky white sap from the leaves and stems can cause mild stomach upset and skin irritation in sensitive individuals.
Pets: Ripe mulberry fruit is generally considered non-toxic for dogs and cats. As with humans, the unripe fruit and plant parts may cause mild gastrointestinal upset if consumed in large quantities.
