Black Mulberry Morus nigra (F)
ABOUT
Morus nigra, commonly known as black mulberry, is a deciduous fruit-bearing tree that has a robust and gnarled appearance, characterized by its furrowed bark which is often dark brown to black in color. The leaves are broad, heart-shaped to ovate, and have serrated margins, showing a luscious green hue. They can display some texture with prominent veins. During the growing season, the tree produces small, inconspicuous flowers which are followed by the fruit. The fruits resemble blackberries and are dark purple to black when ripe, known for being juicy and sweet with a slightly tart flavor. The fruits are commonly enjoyed fresh and are also used for making preserves and desserts.

- Toxicity
To humans
Black mulberry (Morus nigra) is generally not considered toxic to humans. The ripe fruit is edible and is often used in jams, desserts, and wines. There is no well-documented toxicity from ingesting the ripe fruit of the black mulberry tree. However, individuals may experience allergic reactions or digestive discomfort, particularly if they consume unripe berries or other parts of the plant in large quantities.
To pets
Black mulberry fruit is not commonly known to be toxic to pets. In fact, the ripe berries can sometimes be given to pets as a treat. However, as with humans, pets could potentially have an allergic reaction or digestive disturbance if they eat unripe berries or excessive amounts of the fruit. It is always best to introduce any new food to a pet's diet gradually and to consult with a veterinarian if you have concerns about the potential effects of black mulberry on your pet's health.

Interesting Facts
- Feng Shui
The Black Mulberry is not used in Feng Shui practice.
- Zodiac Sign Compitability
The Black Mulberry is not used in astrology practice.
- Plant Symbolism
- Protection: The Black Mulberry is often associated with safeguarding due to its robust nature and the dense canopy it provides, symbolically offering a shield against the outside world.
- Wisdom: As a plant that can live for hundreds of years, the Black Mulberry can represent knowledge and wisdom accumulated over a long life.
- Patient Growth: This tree grows slowly, which can symbolize steadiness, patience, and the importance of a solid foundation in personal or spiritual growth.

- Fertility and Prosperity: Its abundant fruit production once made it a symbol of fertility and prosperity, as it was believed to bless the land with bountiful yields.
- Sacrifice: In some cultures, because the tree suffers for its fruits, stripping itself bare each season, it can represent the idea of sacrifice for the greater good.
- Water
The Black Mulberry tree should be watered deeply once a week during the growing season, especially if there has been little to no rainfall. In hot and dry conditions, you may need to water twice a week. Ensure the water penetrates deeply into the soil, reaching the roots; each watering session should provide about 15-20 gallons for mature trees. During the winter months, reduce watering frequency as the tree requires less moisture. It's essential to avoid overwatering as this can lead to root rot.
- Light
The Black Mulberry performs best in full sunlight, meaning it should receive at least six hours of direct sunlight each day. A spot that offers unfiltered sunlight throughout the majority of the day is ideal for this plant. However, the tree can tolerate partial shade, especially in hotter climates.
- Temperature
Black Mulberry trees thrive in a range of temperatures and can survive in conditions as cold as 10°F, making them suitable for many non-tropical climates. They perform best, however, in an environment where the temperature ranges between 60°F and 80°F. A mature Black Mulberry can generally tolerate brief periods of high heat or unexpected frost.
- Pruning
Prune the Black Mulberry to maintain its shape, remove dead or diseased wood, and encourage fruit production. The best time to prune is in late winter or early spring before the sap starts to flow. Remove any crossing branches and thin out dense areas of the canopy to allow light and air to penetrate; this helps reduce disease pressure and promotes healthy growth. Pruning should be done annually.
- Cleaning
As needed
- Soil
The best soil mix for the Black Mulberry tree is well-draining, fertile loam with compost enrichment. The ideal pH for Black Mulberry trees should be slightly acidic to neutral, ranging from 6.0 to 7.5.
- Repotting
Black Mulberry trees grown in pots should be repotted every 2 to 3 years to prevent root bounding and replenish nutrients.
- Humidity & Misting
Black Mulberry trees prefer moderate humidity levels but are adaptable to various conditions and can tolerate dry to humid climates.
- Suitable locations
Indoor
Ensure full sun, prune to manage size, and use large pot with drainage.
Outdoor
Plant in full sun, provide ample space, and protect from strong winds.
Hardiness zone
6-10 USDA
- Life cycle
Morus nigra, also known as Black Mulberry, begins its life cycle as a seed, which germinates in the soil under the right conditions of warmth and moisture. The plant emerges as a seedling with a characteristic pair of heart-shaped leaves distinct to mulberries. As it grows into a juvenile plant, it develops a woody stem and branches out, becoming a sapling. Over several years, it matures into an adult tree capable of flowering; the flowers are typically inconspicuous, and pollination is often aided by wind or insects. After pollination, the flowers develop into small, deep purple to black aggregate fruits, which can be harvested during the summer months. The tree can live for several decades, continuously going through annual cycles of growth, flowering, and fruiting.
- Propogation
Propogation time
Spring-Early Summer
The most common method of propagation for Morus nigra, known commonly as black mulberry, is by taking softwood cuttings in the late spring or early summer. A softwood cutting is a shoot that is not yet mature and typically has a green and flexible stem. To propagate black mulberry from cuttings, take a cutting 4 to 6 inches (approximately 10 to 15 centimeters) in length from a healthy branch, making sure it has at least two sets of leaves. Remove the leaves from the lower half of the cutting to expose the nodes, as this is where roots will develop. Dip the cut end into a rooting hormone to enhance root growth and plant the cutting into a moist soil mixture, ensuring at least one set of leaf nodes is buried. The container with the cutting should be placed in a well-lit area but out of direct sunlight to avoid wilting. Keep the soil consistently moist until the cutting takes root, which is typically evident by new growth at the top of the cutting.
