7 Heritage Apple Trees from Brogdale for a 30-Metre Orchard Row

Brogdale Collections at Faversham holds the National Fruit Collection on behalf of Defra, and its grafting service propagates accessions to order on a range of rootstocks. For a 30-metre row, MM106 is the practical default: it produces a tree of roughly 3 to 4 metres at maturity, accepts a 4-metre spacing, and starts cropping in year three to four. Seven trees at 4 metres use 24 metres of centre-to-centre distance, leaving the end trees clear of any boundary by a metre or more.

The selection logic is built around three constraints: flowering groups need to overlap so the trees set fruit, ripening should run in sequence so harvest is spread beyond a single short glut, and the row needs enough disease tolerance that one bad scab year does not strip every tree. Pollination groups at Brogdale run from 1, the earliest flowering, to 6. Groups 2 through 4 overlap freely.

Start the row with a triploid: Bramley’s Seedling

Bramley’s Seedling sits in flowering group 3 and is a triploid, meaning it carries three sets of chromosomes and produces sterile pollen. It cannot pollinate its neighbours and needs two diploid partners flowering at the same time to set its own crop. That makes it a deliberate first tree in the row, because every later choice has to cover its pollen deficit.

The tree is vigorous. On MM106 it will push toward the upper end of the 4-metre allowance, and on a more dwarfing stock it sulks. The fruit is the standard British cooker, picked in early October, storing into March in a cool shed at 3 to 5 degrees. A single mature Bramley can yield well over 20 kilograms in a good year, more cooking apple than most households use, so one tree is plenty for most kitchens.

Scab susceptibility is moderate. In a wet Kent spring the foliage will show lesions, and the usual countermeasure is open pruning that moves air through the canopy. Triploid vigour works against that openness, so winter pruning has to be assertive.

Egremont Russet, for the position nobody waters

Dry, free-draining ground at the south end of a row is where Egremont Russet earns its keep. It flowers in group 2, tolerates poorer soil than most dessert varieties, and its thick russeted skin resists the cracking that splits thinner-skinned apples in a dry-then-wet autumn. The flavour is nutty and dense, with a low juice content that suits people who dislike a watery apple.

It is a tidy, upright grower, easily the most compact of the seven on MM106, and it crops reliably without the biennial swing that afflicts heavier dessert types. Pick from late September. It eats well off the tree and holds firm into December.

Because it flowers in group 2, it brackets the lower edge of the Bramley’s group 3 window. The overlap is partial but sufficient in most seasons. If the row needs a hedge against a cold snap shortening the flowering period, the trees that follow tighten that overlap considerably.

Discovery and Worcester Pearmain handle the early end

Discovery is the first apple of the British season worth eating, ready from mid to late August, with a flush of red over cream flesh and a faint strawberry note that fades within days of picking. It has no storage value. In a long row, an early variety gives fruit when nothing else is ready and leaves the storage shed free.

Worcester Pearmain follows in early September, flowering in group 3, which puts it squarely in the Bramley pollination window and makes it one of the two diploid partners the triploid requires. Worcester is prone to scab and the fruit bruises easily, so it is best eaten direct from the tree. Its commercial decline came down to that fragility, but in a private row where the fruit travels three metres to a kitchen, the bruising tendency matters far less.

Planting Discovery and Worcester adjacent compresses the early harvest into a six-week run from mid-August. Both are group 2 to 3 flowerers, so they reinforce the pollination overlap that the triploid Bramley depends on. The risk is concentration: two scab-prone trees side by side in a wet year will share inoculum. Spacing them with a more resistant variety between is the standard mitigation, and the next selection is built for exactly that gap.

Worcester also throws useful blossom for bees in the second half of April, which matters if the row sits near a vegetable plot that needs pollinators. The flowering is heavy and the fragrance carries.

A scab-resistant break in the middle: Ashmead’s Kernel

Ashmead’s Kernel, a Gloucester variety dating to the early 18th century, flowers in group 4 and carries genuinely good field resistance to scab. Placed between the scab-prone Worcester and the later varieties, it acts as a low-inoculum buffer in the centre of the row. The fruit is small, dull-skinned, and unpromising to look at, with an intense sharp-sweet flavour that develops in storage and peaks around Christmas.

It is a shy and irregular cropper in its early years and rewards patience more than most. On MM106 it will not bear meaningfully before year four or five, but the eventual fruit keeps until February.

Why the spacing leaves a gap

Seven trees at 4 metres occupy 24 metres of centre spacing, with 2 metres of clear ground at each end. The remaining 6 metres of the 30-metre run is deliberate slack: room to widen one spacing to 5 metres for the vigorous Bramley, or to drop in a future eighth tree once the row’s vigour is known.

Lord Lambourne and Court Pendu Plat close the season

Lord Lambourne, raised by Laxton Brothers and introduced around 1923, flowers in group 2 and crops heavily early in life, often bearing usefully by year three. The fruit is aromatic, ready in late September, and the tree’s compact, spreading habit suits the position before the row’s final, slowest tree. It is one of the more dependable croppers in the seven, which balances the unreliability of Ashmead’s Kernel two trees up the line.

Court Pendu Plat anchors the far end. It is one of the latest-flowering apples in cultivation, sitting in group 6, so late that it often escapes spring frosts entirely, which is its historic reputation as the wise apple of medieval orchards. The very late flowering creates a problem: it barely overlaps with the group 2 to 4 trees up the row. In practice it sets some fruit from the tail of its own group and from late-lingering blossom on Ashmead’s Kernel in a warm spring, but its set is the least reliable of the seven.

The fruit compensates. It is flat, dense, and intensely flavoured, picked in mid-October and keeping until April in cool storage, the longest keeper in the row. The flesh holds its texture for months where Discovery has gone mealy within a week. Placing it at the end, isolated from the early bloomers, accepts a lighter crop in exchange for late frost escape and long storage life. A grower who wants a heavier set from it can underplant a crab apple such as Malus Evereste nearby, whose extended flowering bridges almost every pollination group.

Across the seven, the harvest runs from mid-August Discovery to mid-October Court Pendu, with storage carrying eating apples from the tree through to the following April. The flowering groups cluster 2 to 4 for five of the trees, with Bramley’s triploid demand met by Worcester and Lord Lambourne, while Court Pendu stands apart at group 6 as the calculated outlier.

Rootstock choice after the paper plan

The spacing math assumes MM106 throughout, although Bramley’s triploid vigour and Court Pendu’s weak set both put pressure on a uniform rootstock choice. A mixed-rootstock row, with a more dwarfing stock under the vigorous cooker and a more vigorous one under the shy late keeper, could even out cropping over fifteen years. The first five years of bearing will show whether that adjustment would have helped.

The far-end tree has the longest storage life and the weakest pollination fit. That is the row’s remaining imbalance: a tree with the strongest keeping life may give the least certain crop.
