How to Grow Wineberries

Rubus phoenicolasius

Perennial

Japanese wineberries are cane fruits similar to raspberries, thriving in full sun to light shade and moist, well-drained soil. Plant with support wires and mulch to conserve moisture. They fruit on last year’s canes: tie in new canes through summer and remove fruited canes at ground level after harvest. Water in dry spells from flowering to fruit swell and net against birds. Berries ripen in midsummer; harvest when the calyx opens and fruits are soft, richly coloured, and pull away easily.

Care Requirements

☀️ Light

Full sun to light shade; sheltered spot ideal

Full sun to light shade. Fruits best in full sun but tolerates partial shade better than most cane fruit. A sheltered spot reduces wind damage to canes.

💧 Watering

Water at flowering and fruit swell

Water regularly from flowering through fruit swell for the juiciest berries. Established plants are fairly drought-tolerant at other times.

🌱 Fertilizing

Spring feed and annual compost mulch

Apply a general-purpose fertiliser in early spring. Mulch annually with compost to feed the soil and retain moisture.

✂️ Pruning

Remove fruited canes; tie in new ones

After fruiting, cut all fruited canes to ground level. Tie in new season's canes to wires for next year's crop. Separate new and fruiting canes for easy management.

🌿 Support

Train on wires; control tip-layering

Train on horizontal wires like raspberries, spaced 60cm apart. Wineberries tip-layer readily, so keep arching canes tied up to prevent unwanted spread.

🍎 Harvesting

Pick when orange-red and easy to pull away

Pick when berries are bright orange-red and pull away easily from the calyx, typically July to August. Sweet and aromatic with a unique flavour.

Growing Tips

Train and label canes

Separate new season’s canes from fruiting ones on opposite sides of the wire for easy pruning.

Post-harvest prune

Cut out all fruited canes to ground level and tie in new canes for next year.

Mulch and moisture

Apply organic mulch yearly and water at fruit swell for juicy berries.

Bird protection

Use netting as berries colour to safeguard the crop.

Pests & Diseases

Pest Raspberry Beetle

Identification: Small brown beetles on flowers; grubs inside ripe fruit (small white larvae near the plug end)

Organic treatment:
  • Shake beetles off flowers onto a sheet in the morning
  • Use pheromone traps to monitor and reduce numbers
Chemical treatment:
  • Spray with pyrethrin at first pink fruit stage
Pest Spotted Wing Drosophila

Identification: Small holes in ripening fruit, fruit collapses and rots quickly, tiny larvae inside fruit

Organic treatment:
  • Use fine mesh netting over plants from fruit colouring
  • Set apple cider vinegar traps to monitor and reduce numbers
  • Harvest promptly and remove any damaged fruit
Chemical treatment:
  • No home-garden chemical treatments currently approved for this pest in the UK
Pest Birds

Identification: Pecked or missing fruit, especially as berries ripen and colour

Organic treatment:
  • Net plants with fine mesh before fruit colours
  • Use bird scarers or reflective tape as a deterrent
Chemical treatment:
  • Not applicable
Disease Cane Blight Paraconiothyrium fuckelii

Symptoms: Dark brown lesions at the base of canes, canes become brittle and snap easily, leaves wilt above the lesion

Treatment: Cut out and burn affected canes below the lesion. Disinfect secateurs between cuts

Prevention: Avoid damaging cane bases when hoeing. Ensure good air circulation between canes

Disease Grey Mould (Botrytis) Botrytis cinerea

Symptoms: Fuzzy grey mould on ripening fruit, especially in wet weather. Fruit rots on the plant

Treatment: Remove and destroy affected fruit promptly. Improve air circulation

Prevention: Space canes well and thin to allow airflow. Avoid overhead watering during fruiting

Spacing & Planting

Plant spacing 100 cm
Row spacing 200 cm
Mature height 200 cm
Mature spread 200 cm

A relative of the raspberry (Rubus phoenicolasius). Forms arching canes and can spread. Provide support and space for access.
