8 Step Quince Tree Fan Training Routine with Vranja on a South Wall

Step one: wire the wall before the tree arrives

Put the support system up before the maiden arrives. Galvanised 2.5mm wire fixed at 30cm vertical intervals carries the fan, with vine eyes screwed into the brick mortar joints so the wire sits 8cm off the face. That gap keeps air moving behind the leaves and lowers the risk of July scorch from brick radiance on Vranja foliage. The lowest wire is set 40cm above the soil, and a south wall 1.8m high takes five horizontal wires before the coping cuts off the run.

Vranja is sometimes catalogued as Bereczki. On Quince A rootstock it is a heavy cropper and can make more growth than loose wires will manage. Straining bolts at each end of the wire allow retensioning during the second and third summers, when the rib arms thicken and draw the line slack. Plant the maiden whip 22cm out from the wall, leaning into it at about 45 degrees, and keep the graft union 8cm above the soil surface.

Step two: make the first cut and choose the first arms

At planting, cut the maiden back to 45cm at a point where three sound buds sit within the top 10cm. The top bud becomes the leader, while the two beneath it form the first pair of ribs. By the following June, tie those side shoots to canes set 40 degrees from vertical and fixed onto the lowest two wires. Once the side arms are growing strongly, usually by the end of the first season, remove the central leader above them.

The two chosen buds should face left and right. Buds aimed into the brick or out into the path give awkward ribs from the start, and a shoot pointing at the masonry crowds the wall and shades its own fruit spurs. The cane angle matters more than the first angle of the shoot, because the shoot is tied to the cane and the cane establishes the permanent line. In a warm position, Vranja extension growth can reach 90cm during that first summer, so ties and cane positions need checking every three weeks while growth is active.

Step three: spread the ribs over the next two summers

In the second dormant season, cut each of the first-tier arms back to 45cm, again to three buds. That pruning produces four developing ribs in year two. By the end of year three, the fan should carry eight ribs across the wall in an even spread.

At maturity, the target is one rib for roughly every 10cm of vertical wall space. Each rib is tied to its own cane, and the canes are secured to the horizontal wires.

Spacing governs how much light reaches the fruiting wood. If ribs are closer than 8cm, they shade one another and the lower spurs stop fruiting within two seasons. If the spaces open beyond 14cm, bare wall is left unused and some of the warmth from the south aspect is wasted. A 2m allocation is enough for eight to ten ribs on Quince A.

Do not pinch the extension shoots during these framework years. Let them run, tie them in, and leave shortening until a rib has reached the top wire.

Once a rib reaches the coping, cut it back each winter to a downward-facing bud to hold its length. From that point, the fruiting spur system starts to matter more than extension.

By the third winter, the structure is mostly set. Later pruning is maintenance work, aimed at keeping spurs productive and stopping the fan from thickening into a hedge.

Cropping in the fourth year depends heavily on the regularity of the rib angles in the first three seasons. A rib left upright for a season tends to suffer when it is forced down later, while one trained at its final angle from the start thickens into its position without the same breakage or choking.

Step four: pinch the fruiting laterals in summer

From the fourth year onward, treat the laterals growing off the ribs much like those on a cordon apple. In late July, pinch each lateral back to five or six leaves above the basal cluster. The reduced shoot then feeds fruit bud formation at the base. Any sub-laterals that grow after that are pinched to one leaf in early September.

This is the standard cordon pruning regime applied to a wall fan. Vranja fruits on spurs and also on the tips of two-year wood, so leave a share of one-year laterals unpinched and tie them in to renew the spur system over a three-year cycle. If every lateral is cut back to spurs, the tree gradually loses the tip wood that also carries fruit.

Step five: feed the wall tree and avoid the ericaceous mistake

A quince on a warm wall dries quickly at the root. The same reflected heat that helps ripen the fruit also bakes the rooting zone. In March, mulch with 5cm of garden compost, keeping it a hand’s width clear of the trunk. A spring feed of sulphate of potash at 15g per square metre supports fruit bud formation. After the framework years, keep nitrogen low to avoid soft growth that scorches against the brick.

Ericaceous compost is a common mistake here. That acidic mix is made for blueberries and other lime-hating plants, while quince wants near-neutral soil around pH 6.5 to 7.0 and dislikes acidity lowered by sulphur. Blueberry compost belongs in its own container. For quince fruit size, July and August watering matters more: in dry spells, give a deep soak of 20 litres every five days, directed to the root zone instead of the foliage.

Step six: raise spare plants from hardwood cuttings

Vranja strikes reasonably from hardwood cuttings taken in late autumn, although Quince A rootstock produced by layering or stooling gives a more predictable plant. Use pencil-thick prunings 25cm long, cut just below a bud at the base and above a bud at the top, then insert them two-thirds deep into a trench with 5cm of sharp sand in the bottom and leave them undisturbed for a full year before lifting.

A cutting-raised quince grows on its own roots and suckers more freely than a grafted tree, which can suit a free-standing bush yet complicates a trained wall specimen where every rib has a set place. For the fan, a maiden on a named rootstock remains the surer route, with hardwood cuttings better kept for a hedge or for giving away.

Step seven: use the August chip-budding window for gaps

If a rib dies or a gap opens in the fan, chip budding in August can replace it. Take a dormant bud from the current season’s Vranja growth with a small sliver of wood attached, fit it into a matching cut on a stub of rootstock or an adjacent rib, and bind it with grafting tape. The union forms over winter. The bud then breaks the following spring and throws a shoot that can be trained as a replacement rib.

The work falls in the period when the bark still lifts cleanly because sap is moving, usually from mid-July to late August in a temperate climate. Buds cut before they are mature fail to settle properly, and by the back end of the window the bark begins to cling to the wood. A grafting knife with a flat-ground edge makes the matching cuts clean, and the tape is slit to release the bud once growth can be seen the following spring.

Step eight: harvest when colour and scent are right

Leave Vranja fruit on the tree until late October, well after apples are picked, because it ripens slowly and improves with extra hang time. The skin shifts from green to deep gold, and the heavy quince scent builds around the wall as ripeness approaches. Fruit taken before that change remains woody and lacks its full perfume. Frost-damaged fruit bruises and stores poorly, so the crop should come in once the scent and colour have arrived.

Cut the fruit with secateurs, leaving a short stalk attached, and avoid pulling it from the tree. Store the quinces in single layers in a cool shed, away from apples or pears that would take up the scent. Vranja keeps for six to eight weeks and is used cooked, because the raw flesh remains hard and astringent.
