Rubus phoenicolasius

The Japanese Wineberry (Rubus phoenicolasius) is a stunning and productive fruiting shrub that brings colour and flavour to any garden. This hybrid berry, related to raspberries and blackberries, produces deliciously sweet and tart red berries in early summer. With its vigorous growth and ornamental appeal, the Japanese Wineberry is an excellent choice for gardeners looking for an easy-to-grow soft fruit plant. This guide will take you through everything you need to know to successfully grow, prune, and harvest wineberries for years of abundant fruit.

The Japanese Wineberry is native to Korea and China and is closely related to raspberries and blackberries. It grows as a deciduous shrub with bristly, red stems that add an ornamental touch to the garden. The bright red fruits ripen in early summer, enclosed by a protective calyx that opens to reveal the juicy berries.

Unlike raspberries or blackberries, wineberries are covered in red bristles, giving them a unique appearance. The plant is also highly resistant to pests such as the raspberry beetle, making it an easy-to-grow option for home gardeners.

Planting a Japanese Wineberry is simple, and with the right conditions, it will thrive and bear fruit for many years.

To plant boysenberries, choose a location with full sun and well-draining soil enriched with organic matter. Dig a hole deep enough to accommodate the roots, ensuring the base of the plant is level with the soil surface.

Add well-rotted compost or manure to improve soil fertility. Space each plant about 1.5 metres (5 feet) apart to allow for proper airflow and growth. Mulch around the base of the plant to retain moisture and suppress weeds.

Wineberries will grow well in fertile soil with good drainage. A sunny wall or partial shade location works best for maximising fruit production. These plants are vigorous and can grow to a height of 2.5m or even 3m, so ensure there is enough space for their sprawling canes.

Prepare the soil by adding well-rotted compost or manure. Wineberries prefer moist soil, so it is essential to mulch around the base to retain moisture. Dig a hole deep enough to accommodate the roots, ensuring that the base of the cane is at soil level. Space multiple plants at least 1.5m apart to allow for spreading.

Place the wineberry plant into the hole, spreading the roots out evenly. Fill the hole with soil, firming it gently to remove air pockets. Water the plant well after planting to help establish the roots.

Caring for a Japanese Wineberry plant is straightforward, making it a fantastic addition to any garden.

Watering and Mulching

Regular watering is essential, especially during dry spells. Mulching with compost or well-rotted manure will help retain moisture and suppress weeds.

Feeding

Wineberries are not heavy feeders, but an application of balanced fertiliser in early spring will encourage healthy growth and fruiting.

Supporting the Canes

Tie the canes to a trellis or support system to keep them upright. This will prevent them from sprawling and make harvesting easier.

When to Harvest

Japanese Wineberries ripen between June and July. The berries will start as orange-red and turn dark red when fully ripe.

How to Harvest

• Pick the berries straight off the canes when they are fully ripe.
• The calyx will naturally peel back when the fruit is ready to eat.
• Harvest regularly to encourage further fruit production.

Common Pests and Diseases

One of the advantages of growing Japanese Wineberries is their resistance to pests and diseases. However, you should still keep an eye out for common issues such as:

• Raspberry beetle – Remove any affected fruit to prevent spreading.
• Mildew – Ensure good air circulation by pruning and spacing plants adequately.

Wineberries are vigorous growers and can be easily propagated by layering or taking cuttings.

How to Propagate

• Layering – Bend a low-growing cane to the ground and cover it with soil. New roots will form, and the cane can be separated to grow as a new plant.
• Cuttings – Take softwood cuttings in early summer and place them in moist soil to root.

Wineberries have a sweet and tart flavour, making them perfect for various culinary uses.

Wineberry Recipes

• Wineberry Jam – A delicious spread with a rich flavour.
• Wineberry Crumble – A perfect dessert with a mix of tart and sweet flavours.
• Fresh Wineberries – Enjoy straight off the canes or mixed into salads and smoothies.
