Meet Jostaberry
A thornless hybrid cross between black currant and gooseberry, producing marble-sized dark berries with a unique flavor. Jostaberries combine disease resistance from gooseberry with the rich flavor of black currants in a vigorous, easy-care bush. The plants are self-fertile and highly productive, requiring only basic annual pruning.
When to plant Jostaberry
Jostaberries are propagated exclusively by vegetative means, as they are hybrid crosses that do not come true from seed and often produce infertile seeds. Hardwood cuttings taken in late autumn are the most reliable method: cut eight-to-ten-inch sections of the current season growth, remove the top buds, and insert into well-prepared soil with two buds above ground. Cuttings root readily over winter and can be transplanted the following autumn. Division of established bushes in late winter also works well.

How to grow Jostaberry
Jostaberries are vigorous, thornless shrubs that grow quickly to five or six feet tall and wide. They are remarkably low-maintenance and resistant to many diseases that plague their parent species. Plant in full sun to partial shade in well-drained, fertile soil enriched with compost. Space plants five feet apart for hedging or six to eight feet for individual bushes.
Plant bare-root jostaberries in late autumn or early spring. Water well during the first growing season to establish a strong root system. Jostaberries are self-fertile, but yields improve significantly when a black currant or gooseberry is planted nearby for cross-pollination.
Prune annually in late winter by removing about one-quarter of the oldest branches at ground level, along with any weak, damaged, or crossing growth. This keeps the bush productive with a mix of young fruiting wood. Mulch generously with compost or bark chips. Jostaberries are moderate feeders; apply a balanced organic fertilizer in early spring. These hardy, disease-resistant plants are among the easiest fruit bushes for home gardeners to grow.

Jostaberry's best neighbours
Chives and garlic planted near jostaberries help deter aphids and may discourage big bud mite. Planting a black currant or gooseberry nearby as a pollination partner can significantly improve jostaberry yields. Comfrey grown adjacent provides excellent mulch material when cut. Avoid planting near fennel, which inhibits growth of many plants. Jostaberries make excellent informal hedges and integrate well into mixed fruit garden designs.
Chives belongs beside it. Fennel doesn't.

Feed it well
Jostaberries grow well in a range of soil types but prefer fertile, moisture-retentive, well-drained soil with a pH of 6.0 to 6.8. Amend poor soils with generous compost before planting and top-dress annually. Apply a balanced organic fertilizer such as 5-5-5 in early spring. Avoid excessive nitrogen which promotes dense leafy growth at the expense of fruit. Potassium supports fruit development; supplement with wood ash or greensand if soils are potassium-deficient.

From seed to harvest, stage by stage
Dormant Planting
Jostaberries are most commonly planted as bare-root whips or containerized shrubs during the dormant season, from late autumn through early spring. Bare-root plants establish readily if planted while fully dormant. The root system begins establishing in cool soil before top growth resumes. Young plants may show no visible signs of life for several weeks after planting, which is entirely normal while roots are actively colonizing the soil.
First Bud Break and Leafing Out
As soil temperatures rise in early spring, buds swell and burst to reveal the characteristic lobed, glossy leaves strongly reminiscent of blackcurrant foliage. New canes begin pushing up from the base of the plant with vigor. Young plants establish their framework of 3-5 primary canes in their first year. The growth rate accelerates quickly once the root system is settled. Jostaberry leafs out slightly later than most other Ribes species, helping it avoid the worst late frost damage.
Flowering
Small clusters of pale white to blush-pink flowers appear in early to mid-spring, typically before the leaves are fully expanded. Each cluster carries 3-5 flowers that are largely self-fertile, meaning a single plant will produce a crop without a pollination partner. However, planting two or more jostaberry bushes, or proximity to blackcurrant or gooseberry plants, can increase fruit set and yield significantly. Flowers emerge early enough that late frost is an occasional risk in exposed sites.
Fruit Development
Successfully pollinated flowers develop into clusters of 3-5 berries, initially small and grass-green. The fruits swell rapidly over the following weeks, progressing through green to a red-purple stage before reaching full ripeness at black-purple. At maturity, jostaberries are noticeably larger than blackcurrants — roughly the size of a small gooseberry. Unlike gooseberries, the berries lack the characteristic veining and spines, with smooth skin and a small dried calyx at the tip end.
Harvest
Jostaberries ripen in midsummer, typically from late June through July in Northern Europe and North America. Ripe fruits are deep black-purple, slightly soft, and have an intensely aromatic fragrance combining blackcurrant musk with a gooseberry tartness. Unlike blackcurrants, jostaberries do not all ripen simultaneously — berries in a cluster can be at different stages, requiring picking over several days. The flavor peaks when berries are fully black and yield gently to the touch.
Post-Harvest Growth and Pruning
After harvest, the jostaberry bush continues vigorous vegetative growth, producing new canes from the base that will carry fruit in subsequent years. The bush develops its full productive framework over 2-3 years, ultimately reaching 1.5-2 meters in height and spread. Late summer is the ideal time to prune out the oldest, least productive canes — those 3 years or older — to encourage new basal growth. The characteristic thornless canes make post-harvest pruning a safe and easy task.
Dormancy
As temperatures drop in autumn, jostaberry leaves turn yellow to purple before falling, revealing the attractive arching framework of thornless canes. The bush enters full dormancy by late autumn, requiring a chilling period of 800-1200 hours below 7°C (45°F) to break dormancy and flower properly the following spring. This chilling requirement makes jostaberry well-suited to continental and maritime temperate climates but unsuitable for warm subtropical areas without sufficient winter cold.
Plant in a prepared hole twice the width of the root ball and at the same depth as previously grown. Incorporate well-rotted compost into the planting hole. Cut back all stems to 15-20 cm from the ground at planting time to encourage strong new growth from the base. Water in well even in cool weather. Mulch with 8-10 cm of compost or wood chip to suppress weeds and retain moisture.
Caring for Jostaberry month by month
What to do each month for your Jostaberry
July
You are hereHarvest month for most temperate climates. Pick ripe black-purple berries regularly every 2-3 days — do not wait for the whole cluster to ripen simultaneously. Freeze excess harvest promptly on trays before bagging. After the main harvest, begin post-harvest pruning by removing one-third of the oldest canes at the base.
Harvesting Jostaberry
Jostaberries ripen in midsummer, turning from green to dark purple-black when ready. Unlike black currants, individual berries within a cluster ripen at different times, so multiple harvests over two to three weeks are typical. Pick berries when fully dark and slightly soft. They are larger than black currants, about the size of small grapes, making them easier to harvest. Jostaberries detach cleanly from the strig when ripe. Taste-test before bulk harvesting, as under-ripe berries are quite tart.

Storage & Preservation
Fresh jostaberries keep in the refrigerator for up to one week. Freeze by spreading on trays and transferring to bags for up to twelve months. Jostaberries make excellent jam, jelly, and fruit syrup with a flavor that blends the richness of black currant with the brightness of gooseberry. They work well in pies, crumbles, and smoothies. Their high pectin content means jam sets easily without added pectin. Jostaberry wine has a deep color and complex flavor.
What goes wrong — and the fix
Gooseberry Sawfly
PestRapid defoliation from small, pale green caterpillar-like larvae feeding from the interior of the bush outward.
Big Bud Mite
PestAbnormally swollen, rounded buds in winter and spring; affected buds fail to open or produce distorted growth.
Leaf Spot
DiseaseSmall dark brown spots on leaves that may coalesce, causing premature leaf drop in severe cases during wet seasons.
Troubleshooting Common Problems
The most common complaint is the vigorous growth habit, as jostaberries can become large, spreading bushes that overwhelm small gardens. Regular pruning controls their size. Some gardeners find the flavor too mild compared to black currants, though this makes them more palatable for fresh eating. Birds can strip ripe fruit quickly; netting is advisable. Although resistant to most diseases, they can still be affected by sawfly larvae if the parent species are grown nearby.
Growing Tips
- Plant in full sun for maximum yield and flavor — jostaberry will grow in partial shade but fruit production and sugar content drop significantly. A minimum of 6 hours of direct sun per day is needed for a reliably productive crop.
- Jostaberry is self-fertile and will crop from a single plant, but planting two or more bushes, or growing near blackcurrant or gooseberry plants, significantly improves fruit set through cross-pollination and can increase yields by 20-40%.
- Prune annually using the renovation method: after harvest each year, cut out one-third of the oldest canes at the base, leaving one-, two-, and current-year canes. This rotating structure keeps the bush in its most productive 1-3 year wood and prevents the center from becoming congested and disease-prone.
- The thornless canes are a major advantage at harvest time, but the plant still grows vigorously and can become a large, spreading shrub up to 2 meters tall and wide if unpruned. Budget sufficient space — a minimum of 1.5 x 1.5 meters per plant — or be prepared to manage size with annual pruning.
- Net the bush as fruits begin to color from green to red-purple — birds, particularly starlings and blackbirds, will strip ripe jostaberries within hours of ripening. A simple frame and drape of bird netting is essential for a worthwhile harvest in most gardens.
- Propagate easily from hardwood cuttings taken in autumn. Cut 20-25 cm sections of pencil-thick current-season wood, dip the base in rooting hormone, and insert two-thirds of the cutting's depth into a sandy compost mix. Over winter, cuttings root reliably and can be potted on in spring — a free way to expand your planting.
- Jostaberry is an excellent candidate for fruiting hedges along garden boundaries. Planted 1.2-1.5 meters apart in a row, established plants knit together into a productive, wildlife-friendly barrier that provides privacy, wind protection, and a heavy annual fruit harvest from a small footprint.
- Avoid waterlogged soil — jostaberry roots are susceptible to Phytophthora root rot in consistently wet conditions. If your soil is heavy clay, improve drainage by incorporating sharp grit and compost before planting, or raise the planting position slightly above the surrounding soil level.
- Mulch generously and permanently around jostaberry plants. A 10 cm layer of wood chip or compost, refreshed annually, suppresses the weeds that compete strongly with shallow-rooted Ribes species, retains moisture during summer drought, and feeds the soil as it breaks down — reducing the need for additional fertilizer.
- Jostaberry responds well to an annual application of potassium-rich fertilizer in spring — a high-potassium organic feed such as comfrey pellets or wood ash worked into the soil around the base encourages abundant fruiting, improves fruit flavor and sugar content, and strengthens cane tissue.

Where Jostaberry comes from
The jostaberry (Ribes × nidigrolaria) is a relatively modern horticultural achievement, the product of deliberate interspecific hybridization work conducted in Germany over much of the 20th century. The breeding goal was to combine the superior flavor and vitamin content of the blackcurrant (Ribes nigrum) with the vigor, large fruit size, and thornlessness of the gooseberry, while incorporating disease resistance from the American spreading gooseberry (Ribes divaricatum).
The theoretical possibility of crossing blackcurrants and gooseberries had been explored since the late 19th century, but early attempts produced mostly sterile or unproductive hybrids due to the chromosomal differences between the species. Serious systematic breeding work began in Germany in the 1920s at what would later become the Max Planck Institute for Plant Breeding in Cologne. Researchers eventually discovered that including Ribes divaricatum — a tetraploid North American species — in the cross allowed the production of fertile, vigorous offspring that combined traits from all three parent species.
After decades of selection and evaluation, the Max Planck Institute released the first commercial jostaberry cultivar in 1977, naming it after a combination of the German words for its parent species. The release was met with considerable horticultural interest across Europe, particularly in Germany, Switzerland, the Netherlands, and later in the United Kingdom and Scandinavia. Commercial orchards were established in Eastern Europe, particularly Poland and the Czech Republic, to supply the fresh and processed fruit markets.
In North America, jostaberry cultivation gained interest partly because of its resistance to white pine blister rust, a fungal disease for which Ribes species serve as an alternate host and which led to widespread bans on blackcurrant cultivation across many US states in the early 20th century. Jostaberry's demonstrated resistance to this pathogen has made it legally cultivable in some states where blackcurrants remain restricted.
Today, jostaberry remains a specialist crop rather than a mainstream commercial fruit, occupying a niche as an exceptional home garden plant and small-scale specialty crop. Its combination of large, flavorsome fruit, disease resistance, thornlessness, and cold hardiness has earned it a dedicated following among home gardeners and fruit enthusiasts across temperate regions of Europe, North America, and New Zealand.
