Meet Loganberry
A raspberry-blackberry hybrid producing elongated, dark red berries with a sharp, tangy flavor perfect for cooking and preserving. Loganberry canes are vigorous and thorny, requiring a strong trellis and careful handling during pruning. The tart flavor mellows beautifully when cooked with sugar for jams, pies, and wine.
When to plant Loganberry
Loganberries are propagated vegetatively rather than from seed. Tip layering is the traditional method: in late summer, bend the tip of a vigorous primocane to the ground and bury it three inches deep. The buried tip will root over winter and can be severed and transplanted the following spring. Root cuttings taken from dormant plants in late winter also root reliably. Always start with certified disease-free stock from a reputable nursery to avoid introducing viral diseases.

How to grow Loganberry
Loganberries are vigorous trailing cane fruits that need a sturdy trellis with wires at three and five feet high. Choose a sunny, well-drained site and enrich the soil with compost before planting. Set plants five to six feet apart in early spring. The thorny canes can reach twelve feet or more, so allow ample room for training.
Like other hybrid berries, loganberries fruit on second-year floricanes. In the first year, train the new primocanes along the trellis in one direction. The following summer these canes will produce fruit, while new primocanes grow and should be trained in the opposite direction to keep the two generations of canes separate and organized.
After harvest, remove all spent floricanes at ground level and tie in the new season growth. Water consistently during fruit development and mulch the root zone with straw or bark to conserve moisture. Apply a general-purpose fertilizer in early spring. Loganberries are somewhat susceptible to winter cold, so in marginal areas, untie canes after leaf fall and lay them on the ground under a protective mulch layer until spring.

Loganberry's best neighbours
Thyme and borage planted near loganberries attract beneficial pollinators and predatory insects that help control pests. Alliums such as garlic and chives may deter aphids when planted along the row. Avoid planting near raspberries and other Rubus species to prevent the spread of shared diseases. Nitrogen-fixing plants like clover can be grown as a living mulch between rows to improve soil fertility naturally.
Thyme belongs beside it. Raspberry doesn't.

Feed it well
Loganberries prefer fertile, well-drained, slightly acidic soil with a pH of 6.0 to 6.5 enriched with organic matter. Amend poor soils with compost and aged manure before planting. Apply a balanced NPK fertilizer in early spring and side-dress with compost after fruit set. Avoid excessive nitrogen which promotes vegetative growth at the expense of fruiting. Potassium-rich amendments like wood ash support strong cane growth and good fruit quality.

Hardiness Zone Compatibility
From seed to harvest, stage by stage
Dormancy and Root Establishment
Bare-root or containerised loganberry plants are best planted in autumn or early spring while dormant. During this period the plant directs all energy into developing a deep, fibrous root system. Above-ground growth is minimal, but healthy root development at this stage determines the long-term productivity of the plant. The crown should sit at soil level and canes should be cut back to 20-25 cm after planting.
First-Year Cane Growth
Primocanes (first-year canes) emerge from the crown and grow vigorously throughout spring and summer, reaching 2-3 metres or more in length. These vegetative canes will not flower or fruit in their first year but are building the energy reserves that will fuel next year's fruiting. Leaves are large and composed of three to five leaflets with a slightly crinkled texture inherited from the raspberry parent.
Flowering (Second-Year Floricanes)
In their second year, the overwintered primocanes (now called floricanes) produce lateral shoots bearing clusters of pale pink to white five-petalled flowers in late spring to early summer. Loganberries are self-fertile, so a single plant will set fruit without a pollinator partner, but bee activity significantly increases yield. Each flower cluster can produce 5-15 individual berries.
Fruit Development
After pollination, berries develop over 4-6 weeks, passing through pale green, then red, and finally reaching the characteristic deep burgundy-red to purple-red colour of fully ripe loganberries. The fruit is elongated and somewhat conical, resembling a large elongated raspberry, and can reach 3-4 cm in length. Flavour develops during this phase, building the pronounced tart-sweet character the fruit is prized for.
Harvest
Loganberries ripen progressively over a period of 2-4 weeks in mid to late summer, typically July to August in the northern hemisphere. Ripe fruit is deep red-purple, slightly soft to the touch, and releases cleanly from the plug when gently pulled. Unlike blackberries, the plug does not remain in the berry at harvest. Fruit has a high juice content and a bold, tangy flavour that is more intense than either of its parent fruits.
Post-Harvest Cane Renewal
Once fruiting is complete, the floricanes that have borne fruit begin to die back naturally. These spent canes should be removed to allow the new primocanes (which have been growing throughout the summer) to take their place. This annual renewal cycle is the key to maintaining a productive plant and preventing the build-up of disease. The plant enters a period of gradual growth slowdown as days shorten and temperatures drop toward autumn.
Water in well after planting and mulch generously around the base with well-rotted compost or wood chips to retain moisture and suppress weeds. Avoid nitrogen-heavy fertilisers in the first weeks as these encourage weak top growth before roots are established.

Harvesting Loganberry
Loganberries ripen in midsummer, turning from red to a deep, dark wine-red when fully ripe. They are distinctly more tart than boysenberries or tayberries even when fully ripe, which is their characteristic flavor. Harvest when berries are deeply colored and pull away from the plug with gentle pressure. Wear thick gloves, as the thorny canes make picking painful. Collect berries into shallow containers and process quickly, as they soften rapidly after harvest.

Storage & Preservation
Fresh loganberries are perishable and keep in the refrigerator for only two to three days. Their high acidity makes them outstanding for preserving. Freeze on trays and transfer to bags for up to ten months. Loganberries produce some of the finest fruit wine due to their tart, complex flavor and deep color. They make exceptional jam, jelly, and syrup. Canning in light syrup preserves their vibrant color and tangy character.
What goes wrong — and the fix
Spur Blight
DiseasePurple-brown blotches around leaf nodes on canes in late summer; buds at affected nodes fail to grow or produce weak shoots.
Raspberry Beetle
PestSmall brown beetles feeding on flowers; larvae found inside ripe fruit, causing wormy berries and reduced marketability.
Botrytis Fruit Rot
DiseaseGray fuzzy mold on ripening and harvested berries; fruit becomes soft and mushy, especially in wet, humid weather.
Troubleshooting Common Problems
The thorny canes are the greatest practical challenge, making pruning, training, and harvesting difficult. Thornless varieties solve this issue. Loganberries are susceptible to the same diseases as raspberries, so avoid planting where Rubus species have grown in the past five years. Poor fruit set can result from inadequate pollination during cold or wet weather at bloom time. Canes left untrained become a tangled, unmanageable mass that harbors disease.
Growing Tips
- Plant loganberries in full sun in a sheltered position for the heaviest crops. They will tolerate partial shade but yield drops significantly in less than 6 hours of direct sunlight, and fruit flavour is less concentrated in shadier spots.
- Install a robust support system before planting rather than after. Horizontal wires at 50 cm, 1 m, and 1.5 m on sturdy posts will last the lifetime of the plant and make annual cane training straightforward. Loganberry canes can reach 3 m and need secure support.
- If space is limited, train loganberry canes in a fan system against a south- or west-facing wall or fence. The reflected warmth from a masonry wall encourages earlier ripening and often produces the sweetest fruit.
- Keep new primocanes trained separately from the fruiting floricanes throughout the growing season. A simple method is to tie primocanes vertically up the central post or along one side of the support, leaving the fruiting canes spread horizontally on the wires.
- Never allow the area around the base of the plant to dry out completely during the fruiting season. Irregular watering while berries are swelling causes split fruit and encourages grey mould (Botrytis). A deep organic mulch around the root zone dramatically reduces the irrigation needed.
- Renovate neglected loganberry plants by cutting every cane to ground level in late winter and starting the two-year cycle afresh. While you will lose one season's fruit, this hard renovation often produces a more vigorous and higher-yielding plant than trying to manage a tangle of old and new canes.
- Propagate loganberries by tip layering in late summer. Select a long, healthy primocane, bend the tip down to soil level, and bury the last 15 cm in a small hole enriched with compost. By autumn the tip will have rooted and can be severed from the parent and transplanted the following spring.
- Choose the thornless LY59 variety for most home gardens. It crops as heavily as thorned types, produces berries of equal quality, and makes harvesting, training, and pruning far safer and more pleasant — especially where children are involved.
- Apply a dedicated high-potassium fruit fertiliser (such as sulphate of potash) in early spring as buds break and again as fruit begins to colour. Potassium drives sugar development in the fruit, improving sweetness and depth of flavour in the harvest.
- Watch for signs of cane blight — a fungal disease that causes sudden wilting and death of individual canes — and remove affected canes immediately at the base using clean secateurs, disinfecting the blades between cuts with methylated spirit to prevent spreading the pathogen.

A single mature loganberry plant — typically sold for £8-15 as a container-grown specimen or £5-10 bare-root — can yield 3-5 kg of fruit annually once established. At typical farmers market or pick-your-own prices of £4-8 per 500 g, each plant represents £24-80 of fruit per season. Over a productive lifespan of 10-15 years, the total harvest value of one plant can exceed £400-1,000, representing a return of 30-80 times the original planting cost, even accounting for modest annual maintenance inputs such as fertiliser and netting.
Quick recipes
Loganberry Jam
45 minutesA classic preserve that captures the loganberry's intense tartness and deep fruit flavour. Loganberries are naturally high in pectin thanks to their blackberry parentage, so this jam sets beautifully without the addition of commercial pectin. The resulting jam has a vivid purple-red colour and a complex flavour that is far more interesting than standard raspberry jam. Excellent on sourdough toast, scones, or stirred into plain yoghurt.
5 ingredients
Loganberry Crumble
20 minutes preparation, 35 minutes bakingA simple and deeply satisfying British-style baked pudding that pairs the loganberry's tartness with a buttery, oaty crumble topping. The berry filling is barely sweetened to allow the fruit's natural character to shine, and a pinch of vanilla in the crumble adds warmth without overpowering the fruit. Serve warm with clotted cream, vanilla custard, or a scoop of good vanilla ice cream.
8 ingredientsLoganberry Coulis
10 minutesA vibrant, pourable fruit sauce that can be made in under 10 minutes and transforms simple desserts. The sauce balances the loganberry's natural tartness with just enough sugar to round the flavour, then is strained smooth for an elegant, glossy consistency. Use it drizzled over vanilla panna cotta, spooned around a chocolate fondant, swirled into cheesecake, or used as a sauce base for cocktails and mocktails.
5 ingredientsCulinary Uses
Loganberries are primarily a culinary rather than fresh-eating berry, as their pronounced tartness is best complemented by sugar and cooking. They make exceptional pies, crumbles, and fruit sauces. Loganberry wine and juice are considered some of the finest fruit beverages. Their tart flavor pairs beautifully with rich meats and game as a sauce component. They are high in vitamin C and antioxidants.

Where Loganberry comes from
The loganberry (Rubus × loganobaccus) has one of the most precisely documented origin stories in the history of cultivated fruit. In the early 1880s, Judge James Harvey Logan — a former district attorney turned amateur horticulturist — was growing a collection of blackberry varieties alongside a row of Red Antwerp raspberries in his garden in Santa Cruz, California. His intention was to improve blackberry cultivars through deliberate crossing, but by 1881 he noticed seedlings with characteristics unlike either parent. The resulting plants bore elongated, deep red fruit with a flavour that combined elements of both blackberry and raspberry while possessing a distinctive tartness that set it apart from both. Logan introduced the new fruit to the public in 1883, and it was formally described and named the loganberry in his honour.
Botanists subsequently debated for decades whether the loganberry was a true hybrid or a chance polyploid mutation of the blackberry. Modern chromosome analysis has confirmed it as a natural amphidiploid hybrid, combining the full chromosome sets of both parent species. This hybrid vigour is reflected in the plant's robust growth, heavy cropping, and adaptability across a range of climates.
While initial reception in California was modest, the loganberry was introduced to Britain in the 1890s and rapidly gained popularity in the mild, moist climate of the British Isles. By the early 20th century, commercial loganberry orchards were established across the West Country, Scotland, and particularly in the Vale of Evesham. British fruit breeders played a major role in improving the variety, most notably through work at the East Malling Research Station in Kent, which in 1950 released the LY59 thornless clone — still the most widely grown variety today.
In the United States, loganberry cultivation reached its commercial peak in the Pacific Northwest and Northern California during the 1920s and 1930s, where the fruit was processed for juice, canned preserves, and wine. Commercial production declined in the mid-20th century as softer, sweeter strawberries and raspberries became more popular with consumers, but the loganberry retained a devoted following among home gardeners, jam makers, and craft beverage producers. Today it is enjoying a modest revival among heritage fruit enthusiasts and small-scale growers who value its intense flavour, disease resilience, and generous yield.
