Pear

Pyrus communis

Grown almost exactly like an apple, and harder in Britain for one reason: pears flower a fortnight earlier, straight into the frosts. That single fact drives everything — a warm sheltered site is not a refinement but the difference between fruit and none. The second thing worth knowing is that a pear ripened on the tree is already going soft at the core.

Timing that travels

Beth is pollinated by Concorde, Conference, Doyenné du Comice, Invincible, Onward, Williams' Bon Chrétien, Winter Nelis.

A small early pear on a naturally compact tree, cropping young and heavily. One of the better choices where space is limited and the wait for a first crop matters.

Concorde is pollinated by Beth, Conference, Doyenné du Comice, Invincible, Onward, Williams' Bon Chrétien, Winter Nelis.

A Conference × Comice cross that keeps much of the Comice flavour with Conference's reliability. Compact, precocious and partially self-fertile — the modern default where one pear tree is wanted.

Conference is pollinated by Beth, Concorde, Doyenné du Comice, Invincible, Onward, Williams' Bon Chrétien, Winter Nelis.

The most widely grown British pear and the most forgiving. Its partial self-fertility is why a lone Conference still produces something, and the long narrow fruit it sets without a partner is a recognised outcome rather than a fault.

Doyenné du Comice is pollinated by Beth, Concorde, Conference, Invincible, Williams' Bon Chrétien, Winter Nelis.

Widely held to be the best-flavoured pear and among the hardest to grow well in Britain: it wants warmth and shelter, and in a poor summer it drops its fruit. Flowering in group 4, it needs a late partner rather than a Conference.

Invincible is pollinated by Beth, Concorde, Conference, Doyenné du Comice, Onward, Williams' Bon Chrétien, Winter Nelis.

Bred to flower twice, so a frost that destroys the first blossom does not necessarily cost the crop. That is the reason to choose it on a frost-prone site rather than any quality of the fruit.

Onward is pollinated by Beth, Concorde, Conference, Invincible, Williams' Bon Chrétien, Winter Nelis.

Comice-like flavour on an easier tree. The one thing to know is that it cannot partner Comice itself — a case where overlapping flowering groups give the wrong answer and the recorded pairing overrides it.

Williams' Bon Chrétien is pollinated by Beth, Concorde, Conference, Doyenné du Comice, Invincible, Onward, Winter Nelis.

The classic tinned pear, and one that must be eaten within days of ripening — it goes from hard to over-ripe quickly and will not keep. Known worldwide as Bartlett. This is also the cultivar that makes rootstock notes necessary: it will not form a durable union with quince on its own.

Winter Nelis is pollinated by Beth, Concorde, Conference, Doyenné du Comice, Invincible, Onward, Williams' Bon Chrétien.

A late-keeping pear, small and unattractive but still good eating well into winter when nothing else is left. The reason to grow it is the calendar rather than the fruit.

Rootstocks — the decision that fixes the size

A grafted fruit tree is two plants. The top decides what the fruit tastes like; the rootstock decides how big the tree gets, how soon it crops and whether it needs staking for life.

Pears are grafted onto quince, which brings them into cropping years earlier than their own roots would. Some cultivars are graft-incompatible with quince and are sold with an interstem — the reason such a tree has two visible unions.

Heights are ranges and always will be — the same rootstock behaves differently on light sand and deep loam.

Pruning and training

Every piece of fruit pruning advice follows from one fact: where the plant carries next year's crop.

Fruits on: Spurs on older wood

Fruit forms on short stubby spurs that persist on wood two years old and older. Pruning aims to build and renew those spurs, so the framework is kept and young growth is shortened.

Which wood carries the fruitThree fruiting habits compared. On a spur-bearer such as most apples and pears, fruit forms on short stubby spurs on wood two years old and older, so the older framework must be kept and long new shoots can be shortened. On a tip-bearer, fruit forms at the ends of shoots made last year, so shortening every shoot removes the entire crop. On a cane fruit such as a summer raspberry, fruit forms on canes grown the previous season, which die after cropping and are cut to the ground while this year's new canes are kept.Spur-bearerfruit on old spursshorten new growthTip-bearerfruit at the shoot tipsshortening loses the cropCane fruitcut fruited canes outkeep this year’s canes
Cutting the wrong wood does not damage the plant. It removes the crop, and the loss is not visible until the following summer.

Chalky and alkalineStruggles herePear struggles on chalky and alkaline: The soil is substantially too alkaline for it: it wants pH 6 to 7, and this soil sits around 7.8 to 8.5.

Growing it

  • PlantingChoose the warmest, most sheltered position available — a south or west-facing wall is ideal. Keep the graft union above soil level.
  • ProtectionCover a wall-trained pear with fleece on frosty nights while it is in flower. It is the one intervention that reliably changes the outcome for pears in a cold spring.
  • HarvestingPick pears BEFORE they are ripe. A pear left to ripen on the tree goes soft and brown at the core while the outside still feels firm. Lift and twist; if the stalk parts, pick the whole crop and ripen it indoors.
  • WateringWater newly planted trees through their first two summers, and any tree in grass rather than bare soil, because turf takes the surface water first. Pears are less drought-tolerant than apples on Quince rootstocks, which are shallow-rooted: a dry spell while the fruit is sizing shows up as small, gritty fruit rather than as a wilted tree.
  • FeedingA mulch of garden compost over the root area each spring is enough for a tree in reasonable soil. Where growth is weak — less than about 30 cm of new shoot in a season — apply a general fertiliser in late winter before growth starts. Feeding a tree that is already growing strongly produces soft shoots that scab and canker take first.
