Do all mulberries produce fruit?

No, some cultivars are specifically bred to be fruitless to avoid the mess of falling berries.

How fast do they grow?

Mulberries are generally fast growing trees that can add several feet of height per year.

Mulberries are hardy, fast growing trees that produce delicious, berry like fruit. They are quite adaptable to various soil types and thrive in sunny locations. You will enjoy their lush foliage and the sweet harvest they provide in late spring or summer.

At a glance

Care level: Easy
Plant type: Deciduous tree
Light: Full sun
Indoor light: direct
Water: Every 7 to 14 days
Mature size: 10 to 20 meters
Growth rate: fast
Hardiness: USDA 4 to 9
Bloom time: Mid to late spring

Care

Plant in a spot with plenty of sun to ensure the best fruit production. Keep the soil consistently moist while the tree is young, but mature trees are fairly drought tolerant. Watch for signs of yellowing leaves which may indicate poor drainage or nutrient deficiency.

Watering: Water deeply during dry spells to support fruit development.
Feeding: Apply a balanced fertilizer in early spring before new growth begins.
Pruning: Prune during the dormant winter season to maintain shape and remove dead wood.
Repotting: Repot only if grown in a container, otherwise keep in the ground.
Soil: Well draining, loamy soil
Soil pH: 6.0 to 7.5
Temperature: -25 to 35°C
Humidity: 40 to 70%
Drought tolerance: moderate
Lifespan: Perennial, typically 50 to 100 years.
Deer and rabbits: moderate

Signs it needs repotting

Roots circling the bottom of the pot.
Water running straight through the soil.
Noticeable decline in growth rate.

Safety

People: The milky latex sap found in the leaves and stems can cause skin irritation or dermatitis in sensitive individuals.
Pets: The plant is generally considered non toxic, but the sap can occasionally cause mild skin irritation.
Children: The fruit can stain clothing and skin, and the sap should be kept away from eyes and mouths.
Contact allergens: The milky sap can cause contact dermatitis upon skin exposure.
Airborne allergens: The pollen is highly allergenic and can trigger significant respiratory symptoms during the spring.
Edibility: While the fruit is edible, unripe berries and the milky sap from stems can cause stomach upset or hallucinations if consumed in large quantities.

How to identify it

Heart shaped or lobed leaves
Rough, textured bark on mature trees
Small, catkin like flower clusters
Edible, blackberry like aggregate fruits

Height: 6 to 20m
Spread: 4 to 15m
Leaves: green, deciduous
Flowers: green, white, 1 to 3cm
Fruit: red, purple, black, white, Late spring to summer

Common problems

Popcorn disease — A fungal infection that causes the fruit to swell and look like popcorn.
Scale insects — Small insects that attach to branches and suck sap, weakening the tree.

Growing it

Propagation: cuttings, seed, grafting
When to plant: spring, autumn
Overwintering: Mulberries are hardy and require no special protection in winter, though young trees may benefit from a layer of mulch around the base.
In containers: Mulberries are generally too large for long term container growth, though dwarf cultivars can thrive in large pots of at least 20 gallons.

Hardwood cuttings

Take 8 to 10 inch cuttings in late winter.
Dip the base in rooting hormone.
Plant in a well draining potting mix.
Keep moist until roots develop in spring.

Plant understory shrubs that tolerate partial shade to maximize space beneath the wide canopy.

Grows well with

Elderberry — They share similar moisture needs and thrive in the same woodland edge conditions.
Currants — These shrubs appreciate the dappled shade provided by a mature mulberry canopy.

Similar species

Paper Mulberry — It has similar leaf shapes but is often considered invasive in many regions.

Science

Family: Moraceae
Genus: Morus
Order: Rosales
Class: Magnoliopsida
Native range: Temperate and subtropical regions of Asia, Europe, and North America.
Conservation: Most common species are widespread, though some local populations of native species face threats from hybridization with introduced varieties.

These trees are opportunistic colonizers that thrive in disturbed soils and forest edges.

Value to wildlife: fruit source for birds, nesting cover
Pollinators: bees, beetles
Uses: edible fruit, ornamental shade tree, wildlife habitat
