Jostaberries in the UK: Why They’re Perfect for British Gardens

Ribes nidigrolaria

Jostaberries (Ribes nidigrolaria) are a fantastic addition to any garden, combining the best traits of blackcurrants and gooseberries into a vigorous, thornless bush. This hybrid shrub is perfect for gardeners looking to grow delicious, nutrient-rich berries with minimal maintenance. Whether you’re new to growing fruit bushes or a seasoned gardener, this guide will take you through everything you need to know about cultivating jostaberries successfully.

A jostaberry is a unique hybrid that combines the size and hardiness of a gooseberry with the rich flavour of blackcurrant. The bush forms a big, sprawling shape, making it a great choice for gardens with ample space. Unlike the gooseberry, it is thornless, making harvesting easier and more enjoyable. The berries darken as they ripen, turning a deep reddish-black when ready to eat. These fruits are rich in vitamin C and can be eaten raw, cooked, or bagged for later use.

Jostaberries thrive in a well-drained but moisture-retentive soil, in either full sun or partial shade. If you have restricted space, you can train your jostaberry against a wall or fence. Avoid water-logged areas and choose a location where the plant will have enough room to spread out. The best yield comes from bushes planted in rich, fertile soil, enhanced with homemade compost or well-rotted manure.

When buying jostaberry plants, choose healthy specimens from a reputable nursery. Look for strong stems and leaves and small buds forming along the branches. Avoid any plants that appear unproductive or show signs of pest damage.

When planting in spring, dig a hole large enough to accommodate the roots comfortably. Backfill the hole with soil mixed with well-rotted manure or compost to give your plant the best start. Keep the base of the bush weed-free to prevent competition for nutrients. If planting multiple bushes, space them at least 1.5 metres apart to allow for proper growth.

Jostaberry bushes are easy to grow and require minimal maintenance once established. Regular pruning is essential to maintain an open-centred shape, which helps air circulation and prevents diseases such as mildew and leaf spot. It’s best to prune in late winter while the bush is dormant, removing any unproductive wood and cutting back recent year’s wood to encourage new growth.

While jostaberries are relatively pest-resistant, they can sometimes attract small mammals or insects. To protect the flowers from late frosts, use fleece to protect them on particularly cold nights. Keep an eye out for common problems such as leaf spot and mildew, and treat early if needed.

The fruit is produced in late spring and ripens over the summer months. Jostaberries swell and darken as they ripen, turning a dark reddish-black when ready for picking. Unlike the gooseberry, they are easier to harvest due to their thornless nature. You can eat fresh berries straight from the bush, cook them into desserts and preserves, or freeze them for later use.

Jostaberries are versatile and can be used in a variety of recipes. Their sweeter flavour makes them perfect for muesli and desserts, while their tartness works well in jams and sauces. If the berries are quite tart compared to your taste preference, adding a little sugar will enhance their natural sweetness. They freeze well, allowing you to enjoy their flavour year-round.

Key Points to Remember:

• Jostaberry is a cross between a gooseberry and a blackcurrant, offering the best traits of both
• Plant in full sun or partial shade, in well-drained but moisture-retentive soil
• Space bushes adequately to allow for growth and air circulation
• Prune regularly to maintain an open-centred shape and remove unproductive wood
