How to Grow Mulberry
Morus
Mulberries (black/white) need full sun, deep, well-drained soil, and space—they grow into broad, spreading trees. Plant while dormant and stake young trees. Minimal pruning is needed; shape lightly in summer and avoid heavy winter cuts that bleed. Fruit ripens over weeks from early–mid summer; berries stain and drop easily—site away from patios if this is a concern. Water during establishment and mulch annually. Some seedlings take several years to bear; grafted selections fruit sooner.
Yearly Lifecycle
Care Essentials
Mulch with compost in spring. Established trees rarely need feeding.
Watch For
- Generally pest-free
- Birds
- Canker on damaged wood

☀️ Light
Full sun and shelter for best fruiting
Full sun for best fruiting. Tolerates light shade but crops will be reduced. A sheltered, south-facing position is ideal in the UK.
💧 Watering
Water young trees; mature trees are drought-tolerant
Water young trees regularly during establishment. Mature trees are fairly drought-tolerant but benefit from watering during prolonged dry spells in summer.
🌱 Fertilizing
Compost mulch in spring; rarely needs feeding
Mulch with well-rotted compost in spring. Established trees rarely need additional feeding. Avoid high-nitrogen feeds.
✂️ Pruning
Prune in winter dormancy only; minimal cuts
Prune only in full winter dormancy as mulberry bleeds sap heavily if cut in spring. Minimal pruning needed — remove dead or crossing branches.
🍂 Mulching
Thick spring mulch around root zone
Apply a thick mulch of compost or bark around the root zone in spring, keeping it away from the trunk.
Growing Tips
Plan for size
Allow generous headroom and width; mulberries become large, graceful trees.
Prune in leaf
Do formative tidying in summer to reduce sap bleed and speed healing.
Harvest gently
Lay a sheet and shake ripe branches; fruits detach when fully soft and sweet.
Pests & Diseases
Pest Birds
Identification: Pecked and partially eaten fruit; fruit disappearing before you can harvest; bird droppings on branches
- Drape netting over the tree before fruit ripens, securing at the base to prevent birds getting trapped
- Use bird scarers or reflective tape as a deterrent
- No chemical treatment; physical exclusion is the only effective method
Pest Scale Insects
Identification: Small brown waxy bumps on older stems and branches; sticky honeydew and sooty mould in severe cases
- Scrub off with a stiff brush during winter dormancy
- Spray with plant oil-based winter wash
- Apply systemic insecticide in spring when crawlers are active
Disease Bacterial Canker Pseudomonas spp.
Symptoms: Sunken, discoloured patches on branches that may ooze; bark cracks and peels; dieback of affected branches
Treatment: Cut out cankered wood to at least 15cm below visible damage; sterilise tools between cuts
Prevention: Avoid pruning in spring when sap is rising (mulberry bleeds heavily); prune only in full dormancy; protect wounds
Disease Coral Spot Nectria cinnabarina
Symptoms: Bright orange-pink raised pustules on dead or dying branches; can spread to live wood through wounds
Treatment: Cut out affected branches well below the infection; dispose of prunings — do not compost
Prevention: Remove dead wood promptly; avoid leaving pruning snags; prune in dry weather during dormancy
Popular Varieties
Illinois Everbearing
A cross between white and red mulberry species known for hardiness and a prolonged harvest window. Black fruit is almost seedless and very sweet.
Pakistan
Famous for producing exceptionally long fruit (up to 10cm) with firm texture and rich berry flavour. Less cold-hardy than other varieties.
