How to Grow Loganberries: A Complete British Guide

Loganberries thrive in our British climate, tolerating both rain and cooler temperatures whilst producing generous crops of fruit that make the most brilliant jams and crumbles. Whether you’ve got a proper garden in Surrey or just a sunny fence in a Manchester backyard, loganberries deserve serious consideration. They’re particularly well-suited to our growing conditions, requiring minimal spraying and producing fruit when many other berries have finished. I’ve found them especially rewarding because they fill that gap between summer raspberries and autumn blackberries, giving you fresh fruit throughout late July and August.

How to Grow Loganberries

Getting started with loganberries doesn’t require a huge investment, but having the right materials from the outset makes the whole process considerably easier. I’ve learned through trial and error that skimping on certain items just creates more work later on.

Plants and Growing Materials

You’ll need one or two loganberry canes to start with. I’d recommend buying certified virus-free stock from a reputable nursery rather than accepting cuttings from a neighbour. Loganberries can harbour viruses that seriously reduce yields, and starting with healthy plants makes all the difference. Look for bare-root canes between November and March, or pot-grown plants any time of year, though I’ve found autumn planting gives better establishment.

If you love our growing guides then you may enjoy growing chilli peppers that actually ripen too.

For soil preparation, you’ll want well-rotted manure or garden compost (about a wheelbarrow full per plant), some general-purpose fertiliser, and possibly some sulphur chips if your soil is too alkaline. Loganberries prefer slightly acidic conditions with a pH between 6.0 and 6.5. I’d suggest getting a basic soil testing kit from a garden centre to check your pH before planting.

Support Structure and Equipment

Loganberries are vigorous climbers that absolutely require support. You’ll need either a sturdy fence or a custom-built framework. For a framework, I use 2.4-metre wooden posts (8x8cm thickness) set about 3 metres apart, with four horizontal wires running between them at 60cm intervals. You’ll need galvanised wire (2.5mm gauge works well), vine eyes or eye bolts to attach the wire to posts, a wire strainer to keep everything taut, and sturdy garden twine for tying in the canes.

For ongoing maintenance, keep a good pair of secateurs handy, thick gardening gloves (those thorns are serious business), and some soft plant ties. I also keep a small pruning saw for removing older, thicker canes during winter pruning.

Step-by-Step Instructions

Choosing and Preparing Your Planting Site

Location is absolutely critical for loganberries. They need full sun for the best fruiting, though I’ve successfully grown them in partial shade where they get at least five hours of direct sunlight. They’ll produce fruit in shadier spots, but yields drop noticeably. Avoid frost pockets if possible, as late spring frosts can damage flowers and reduce your crop.

The soil needs to be moisture-retentive but well-drained. Loganberries are thirsty plants, but they hate waterlogged roots. If you’ve got heavy clay like I do in parts of my garden, work in plenty of organic matter and consider planting on a slight mound to improve drainage. Sandy soils need even more organic matter to help retain moisture during dry spells.

I prepare the planting area about a month before planting. Dig over a strip about 60cm wide and 45cm deep where the plants will go. Remove all perennial weeds (bindweed and couch grass are particular nightmares to remove once loganberries are established). Mix in that well-rotted manure or compost, working it thoroughly into the soil. This initial preparation really pays dividends.

Installing Your Support System

Before planting, get your support system properly sorted. I learned this the hard way after trying to install posts around established plants, which was awkward and risky. For a post-and-wire system, dig holes about 75cm deep for your posts, set them in concrete if your soil is light or loose, and let the concrete cure for at least a week before tensioning the wires.

Attach your vine eyes or eye bolts at 60cm, 120cm, 180cm, and 240cm from ground level. Thread the wire through and use a wire strainer at one end to get everything properly taut. Loose wires will sag badly once laden with fruit-bearing canes. If you’re using an existing fence, make sure it’s sturdy enough to take the weight. A fully grown loganberry can be surprisingly heavy, especially when wet.

Planting Your Loganberries

Plant bare-root loganberries between November and March, when they’re dormant. I prefer November planting in milder areas, as it gives the roots time to establish before spring growth begins. Container-grown plants can go in any time, but avoid midsummer when keeping them watered becomes challenging.

Dig a hole large enough to spread the roots out comfortably. Look for the soil mark on the stem showing the previous planting depth, and plant to the same level. I’ve found planting too deep can lead to rotting, whilst too shallow leaves roots exposed. Backfill with your improved soil, firming gently with your boot as you go to eliminate air pockets.

Water thoroughly after planting, even if the soil seems moist. This helps settle the soil around the roots. Space multiple plants about 2.5 to 3 metres apart. They spread considerably, and adequate spacing improves air circulation, reducing disease problems.

Training the Canes

This is where loganberries differ significantly from other soft fruit, and getting the training right makes future management so much easier. The key principle is keeping fruiting canes separate from new growth. I use what’s called the ‘fan system’, which I find most practical for home gardens.

In the first year, tie your new canes to the wires as they grow, spreading them out in a fan shape to the left and right of the plant. These canes won’t fruit in their first season, but they’re building strength for next year’s crop. By autumn, you should have several strong canes trained along the lower wires.

During the second summer, these established canes will produce flowers and fruit. Meanwhile, new canes will emerge from the base. Here’s the crucial bit: train these new canes vertically up the middle, keeping them separate from the fruiting canes on either side. This keeps them out of the way during picking and makes pruning straightforward.

Watering and Feeding

Loganberries need consistent moisture, particularly during flowering and fruit development from May through August. I’ve found that irregular watering leads to smaller berries and can cause them to drop prematurely. During dry spells, give them a thorough soaking once or twice weekly rather than daily sprinkles. A good mulch of compost or well-rotted manure applied in spring helps retain moisture and suppresses weeds.

Feed in early spring with a general-purpose fertiliser, scattering about 100g per square metre around the base of plants. Avoid high-nitrogen feeds later in the season, as these promote soft growth that’s vulnerable to winter damage. I give mine a potassium-rich feed (something like sulphate of potash) in late June to support fruit development and help the new canes ripen properly for winter.

Harvesting Your Crop

Loganberries ripen from mid-July through August, usually a couple of weeks after summer raspberries finish. They’re ready when they turn a deep burgundy colour and pull away easily from the plug (the white core that stays on the plant). Unlike blackberries, they won’t ripen further once picked, so timing matters.

Pick every two or three days during peak season. I harvest in the morning once the dew has dried, as wet berries don’t store well. They’re quite soft when ripe, so handle gently and use shallow containers to avoid crushing the bottom layers. Expect about 4 to 5kg from an established plant in a good year, though yields vary with growing conditions.

Winter Pruning

Prune in autumn after fruiting finishes, typically September or October. This is wonderfully straightforward with proper training. Simply cut down all the canes that produced fruit this year, right to ground level. These won’t fruit again, and removing them prevents disease build-up and lets light and air reach the new canes.

Take those new canes you’ve been training vertically and fan them out to replace the old ones, tying them along the wires where the fruiting canes were. Select about six to eight of the strongest canes and remove any weak or damaged growth. This gives you a fresh framework ready for next year’s crop. I burn or dispose of the old canes rather than composting them, particularly if I’ve noticed any disease issues.

Common Mistakes to Avoid

Overcrowding and Poor Air Circulation

I see this constantly in gardens around Hampshire where I help out occasionally. People plant loganberries too close together or fail to thin out the canes, creating a tangled mess that’s nightmare to manage and harvest. This dense growth holds moisture and creates perfect conditions for fungal diseases like botrytis and cane spot.

Stick to that 2.5 to 3-metre spacing between plants, and don’t be afraid to remove excess canes. More canes doesn’t mean more fruit. In my experience, six to eight well-spaced, vigorous canes produce far better than a dozen crowded ones. The improved air circulation also means fruit dries quicker after rain, reducing rotting.

Neglecting Virus-Infected Plants

Virus diseases are the single biggest problem with loganberries, causing yellowing leaves, stunted growth, and disappointing crops. The frustrating thing is that symptoms often don’t show immediately, so infected plants can look fine initially. Always buy certified stock from reputable suppliers rather than accepting free plants from unknown sources.

If your established plants start showing virus symptoms (distorted leaves, yellow mottling, poor growth despite good care), you need to dig them up and destroy them. I know it’s painful, but there’s no cure, and the viruses spread to healthy plants. Don’t replant loganberries in the same spot for at least three years, as viruses can persist in the soil.

Inadequate Support Structures

I’ve watched several friends’ loganberry setups collapse under the weight of mature plants, usually during a summer storm when everything’s laden with fruit. Those canes are heavy and the wind catches them like sails. Whatever support you install needs to be seriously robust, with posts firmly anchored and wires properly tensioned.

Don’t rely on lightweight trellis panels or flimsy fencing. If you’re using an existing fence, check it’s structurally sound first. I’ve reinforced several questionable fences with additional posts before planting loganberries against them, and it’s always been worthwhile.

Wrong Pruning Timing

Pruning loganberries in spring or early summer removes the canes that would produce your crop, as they fruit on the previous year’s growth. I once watched a neighbour enthusiastically ‘tidy up’ their loganberries in March, cutting everything back neatly. They got precisely no fruit that year and couldn’t understand why.

Always prune after fruiting finishes in autumn. The only exception is removing obviously dead, diseased, or damaged material, which you can do any time. If you’re ever unsure which canes to remove, wait until fruiting. The canes bearing fruit are the ones you’ll cut out afterwards.

Expert Tips

Maximising Flavour and Yield

The eating quality of loganberries improves dramatically with proper ripening. I’ve found that berries picked just slightly underripe are disappointingly sharp, whilst those left an extra day or two develop a wonderful balance of sweetness and acidity. Look for that deep burgundy colour and a slightly soft feel.

For larger berries and heavier crops, adequate water during fruit swell makes an enormous difference. From when flowers first open until the last berry ripens, don’t let plants dry out. A thick mulch helps, but in dry periods like we’ve experienced recently, regular watering is essential. I use a leaky hose along the row, which delivers water slowly and deeply.

Managing in Small Spaces

Even a small garden can accommodate loganberries if you’re creative with training. I’ve seen excellent results with single plants trained along house walls, garage sides, or boundary fences in gardens around Bristol and Bath. The key is using the vertical space efficiently.

Try the ‘rope’ method for tight spaces. Train all fruiting canes along the wires in one direction (say, to the right), whilst training new canes to the left. After fruiting, remove the old canes from the right and redirect the new ones that way. It takes a bit more attention but works brilliantly in narrow borders.

Pest and Disease Management

Loganberries suffer from fewer pests than many fruits, but birds absolutely love the ripe berries. Netting is the only reliable solution. I drape netting over the whole structure once berries start colouring, making sure it doesn’t touch the fruit directly (birds will peck through). Proper support structures make netting much easier to manage.

Raspberry beetle can affect loganberries, causing small grubs in the fruit. If you notice this, a few applications of approved insecticide at the flowering stage controls them, though I’ve generally found loganberries less troubled than raspberries. Cane diseases like spur blight occasionally appear as purple patches on canes. Cut out affected canes promptly and improve air circulation.

Extending the Season

Loganberries naturally fruit in mid to late summer, but you can extend this slightly. Plants against warm, south-facing walls ripen a week or two earlier, whilst those in cooler, shadier spots fruit later. I’ve got plants in both situations, giving me a longer harvesting period.

There’s also a thornless variety called ‘LY654’ that I’ve grown alongside the standard thorny type. The thornless version fruits slightly later and is absolute joy to handle and harvest. The fruit quality is comparable, though I find the thorny type slightly more vigorous and productive. Growing both gives you fruit from mid-July through early September.

Frequently Asked Questions

How long do loganberries take to fruit?

Loganberries typically produce their first crop in their second summer after planting. You might get a few berries in the first year if you plant pot-grown stock in autumn, but the main cropping begins in year two. Plants reach full productivity by their third or fourth year and can continue producing well for 10 to 15 years with proper care. The wait might seem long, but I’ve found they’re worth it. Once established, they’re incredibly reliable croppers that require minimal maintenance compared to annual vegetables.

Do loganberries need full sun to grow well?

Loganberries perform best in full sun, producing the heaviest crops and sweetest fruit with at least six hours of direct sunlight daily. However, they’re more shade-tolerant than many fruits, and I’ve successfully grown them in partial shade where they receive about four to five hours of sun. In shadier conditions, expect smaller yields and slightly more tart berries, but they’ll still crop reasonably. Avoid deep shade entirely, as plants become weak and unproductive. North-facing walls work if they’re open to the sky, but south or west-facing positions are ideal.

Can I grow loganberries in containers?

You can grow loganberries in large containers, though they’re happier in the ground. Use a container at least 45cm wide and deep, with excellent drainage. John Innes No.3 compost mixed with some ericaceous compost works well, providing the slightly acidic conditions loganberries prefer. Container plants need much more frequent watering and feeding than those in the ground. Feed every fortnight during the growing season with a liquid fertiliser. Support is still essential, so position containers against a wall or fence where you can train the canes. Expect smaller yields than ground-planted specimens.

Why are my loganberry leaves turning yellow?

Yellow leaves usually indicate either nutrient deficiency or virus infection. If older leaves yellow whilst new growth stays green, this suggests nitrogen deficiency. Apply a balanced fertiliser and mulch with compost to address this. If yellowing appears as mottling or patterns on younger leaves, particularly with distorted growth, suspect virus disease. Unfortunately, viruses can’t be cured, and affected plants should be removed and destroyed. Yellowing can also result from waterlogging, so check your drainage. Iron deficiency causes yellowing between leaf veins on alkaline soils, which you can treat with sequestered iron.

How do I know when loganberries are ripe?

Ripe loganberries turn a deep burgundy or wine-red colour and feel slightly soft when gently squeezed. The most reliable test is whether they pull away easily from the plant. When ready, they should come away cleanly with a gentle tug, leaving the plug behind on the plant. Unripe berries resist pulling and taste sharply acidic. I’ve found that berries continue darkening for several days after they first colour, and waiting that extra day or two makes a huge difference to flavour. Pick regularly once they start ripening, as overripe berries become mushy and may drop off.

What’s the difference between loganberries and tayberries?

Both are raspberry-blackberry hybrids, but they’re different crosses with distinct characteristics. Loganberries are generally larger, darker, and more tart, with a robust flavour that’s brilliant for cooking and preserving. Tayberries are slightly smaller, sweeter, and more aromatic, tasting more like raspberries with excellent eating quality fresh. Tayberries ripen a week or two earlier than loganberries. In terms of growing, they’re very similar in requirements and cultivation, though I’ve found tayberries slightly less vigorous. If you enjoy sharp, tangy flavours and want fruit for jam-making, choose loganberries. For sweeter eating berries, tayberries might suit better.

Moving Forward with Loganberries

Growing loganberries successfully comes down to understanding their basic needs and staying on top of the annual training and pruning cycle. They’re genuinely one of the easiest soft fruits once established, needing far less fussing than strawberries or gooseberries in my experience. The initial setup with support structures requires some effort and investment, but it’s a one-time job that lasts for years.

Start with one or two certified plants, get your support sorted properly, and be patient through that first year whilst they establish. The training system might seem complicated initially, but after you’ve done it once, the logic becomes clear and it’s straightforward to maintain. Those generous crops of tart, flavourful berries make the effort worthwhile, and you’ll wonder why more British gardeners don’t grow these wonderful fruits.

I’ve found loganberries particularly rewarding because they’re so versatile in the kitchen. Fresh in crumbles, cooked into jam, or frozen for winter puddings, they bring that proper old-fashioned fruit flavour that you just can’t get from shop-bought berries. They’re part of our horticultural heritage and deserve a place in more gardens across the country.
