Pear trees

How should you choose a pear tree?

Choosing a pear tree involves more than finding a famous cultivar or a fruit with an appealing flavour. Reliable cropping depends on climate adaptation, flowering period, pollination, disease behaviour, rootstock, soil, harvest season and the intended use of the fruit.

Our collection includes heritage and regional cultivars, dessert pears, cooking pears and perry pears, together with varieties selected for early ripening, storage life, fruit quality or useful behaviour in humid European climates.

A celebrated pear may prove disappointing when it is poorly suited to the local soil, flowers without a compatible pollinator or requires more summer warmth than the site can provide.

A less familiar cultivar that ripens reliably, remains reasonably healthy and produces regularly may be a much better choice for a garden or orchard.

Choose a pear according to its intended use

European pears and Asian pears ripen differently

Most cultivars in this category belong to the European pear, Pyrus communis. They should not be treated in the same way as nashi or Asian pears.

European pears generally develop their characteristic melting texture after harvest. Nashi pears are normally allowed to ripen more completely on the tree and retain a crisp, apple-like texture.

Leaving a European pear on the tree until it feels fully soft can produce internal breakdown, coarse flesh or browning around the core before the outside appears overripe.

Conversely, picking far too early may produce a pear that shrivels, remains hard and never develops its expected sweetness or aroma.

Extend the pear harvest and eating season

Planting several cultivars can spread the harvest from summer into autumn and provide fruit for consumption throughout winter.

Early pears generally ripen quickly and keep for only a short period. They should be eaten or processed soon after harvest.

Autumn cultivars may keep for several weeks and can be brought into a warm room progressively for ripening.

Winter pears are picked late but may not reach their best eating quality until they have experienced a period of cold storage followed by ripening at a milder temperature.

It is important to distinguish the picking period from the eating period. A pear harvested in September may not be ready to eat until October or later.

Harvest periods are indicative and vary according to country, region, exposure, rootstock, crop load and seasonal weather.

Picking maturity and eating maturity are different

Picking maturity is reached when the pear has completed enough of its development on the tree to ripen normally after harvest.

At this stage, the fruit may remain firm, green and unsuitable for immediate eating.

Eating maturity is reached later, once the flesh has softened, the aroma has developed and the balance between sweetness, acidity and texture corresponds to the characteristics of the cultivar.

Between these stages, some pears require only a few days at room temperature, while others need several weeks or months of cold storage before they can ripen correctly.

The exact process depends on the cultivar. Summer, autumn and winter pears should not all be harvested or stored in the same way.

How can a pear be judged ready for picking?

No single sign is completely reliable. The usual harvest period of the cultivar should be combined with observations of background colour, ease of detachment, seed development, firmness and flavour.

Hold the pear in the palm of your hand, raise it towards a horizontal position and turn it gently. When picking maturity approaches, the stalk normally separates without a strong downward pull.

A pear that remains firmly attached may need more time, although ease of detachment varies between cultivars.

The background skin colour often becomes slightly lighter as maturity approaches, changing from dark green towards pale green or greenish yellow.

The seeds usually become darker, but seed colour alone is not sufficient because the timing differs between cultivars and seasons.

Taste representative fruit rather than relying on one pear from the warmest side of the tree. A pear intended for storage may still be firm, but should no longer have completely immature, grassy flesh.

Why should pears not be left to become soft on the tree?

Many European pears ripen from the inside out when left on the tree for too long.

The flesh around the core may become brown, coarse or overripe while the outer part of the fruit still feels relatively firm.

Late picking also reduces storage life and increases susceptibility to bruising, internal disorders and fungal decay.

For most dessert and storage pears, it is preferable to harvest at physiological maturity and complete the ripening process under controlled conditions.

This general rule does not eliminate cultivar differences. Some early pears can remain on the tree until close to eating maturity, while winter cultivars require much earlier picking relative to their final eating date.

How should pears be ripened after harvest?

Once the required storage period has been completed, move a small quantity of fruit into a room at a moderate temperature.

Check the pears daily because the change from firm to fully ripe may occur rapidly.

For many cultivars, slight softness near the neck around the stalk indicates that the flesh is approaching eating maturity.

Do not wait for the entire fruit to become very soft. By that stage, the centre may already be overripe.

Ripen only the quantity likely to be eaten within a few days and keep the remaining fruit in cold storage.

Pears release ethylene and may ripen more quickly beside ripe apples, bananas or other ethylene-producing fruit. This can be useful for a small batch but may cause an entire stored crop to advance too quickly.

Storing pears successfully

Only healthy, dry and undamaged fruit should be selected for storage.

Separate bruised, split, insect-damaged and stalkless pears for immediate use or processing.

Store the fruit in shallow trays or crates so that it is not crushed by the weight of several layers.

A cool, dark and ventilated environment with relatively high humidity but no persistent condensation is suitable for many cultivars.

A refrigerator provides consistent conditions for small quantities, while a cold cellar or fruit store may be suitable where temperatures remain low and stable without freezing.

Inspect stored pears regularly and remove any fruit that begins to soften, leak or develop rot.

Storage potential varies greatly by cultivar. A summer pear cannot be turned into a winter-storage pear simply by keeping it colder.

Pear tree pollination

Most pear trees crop more reliably when a genetically different cultivar flowers at a compatible time nearby.

Some cultivars are described as partially self-fertile and may produce fruit alone under favourable conditions, but cross-pollination normally improves yield and regularity.

Planting at least two compatible cultivars is therefore the safer option unless suitable pear trees already grow in neighbouring gardens or orchards.

Flowering periods must overlap sufficiently, but simultaneous flowering does not always guarantee complete genetic compatibility.

Some triploid cultivars produce pollen of limited fertility. They can receive pollen and produce fruit but should not be relied upon as the only pollinator for another tree.

Cold, wind and prolonged rain during flowering can reduce the activity of bees and other insects. Compatible cultivars cannot compensate completely for exceptionally poor flowering weather.

Choose a rootstock suited to the soil and available space

The rootstock influences vigour, mature dimensions, time to first cropping, anchorage, soil adaptation and the eventual form of the tree.

Some pear cultivars are incompatible with quince

Not every European pear cultivar forms a durable and productive graft union directly with quince rootstock.

An incompatible combination may grow poorly, form a weak graft union or decline after several years.

Where a cultivar is known to be incompatible, a short section of a compatible pear cultivar can be used as an interstem between the rootstock and the desired variety.

This allows the final tree to retain much of the size-controlling effect of the quince while avoiding direct incompatibility.

Compatibility is therefore part of the production method and should be considered alongside the advertised vigour of the rootstock.

Which soil suits a pear tree?

Pear trees generally prefer deep, fertile and well-structured soil with sufficient moisture during growth but without prolonged waterlogging.

Soil requirements vary with the rootstock. A vigorous pear rootstock may explore deeper ground and tolerate temporary drought better than a shallow-rooted quince rootstock.

Some quince rootstocks can develop iron chlorosis in highly calcareous soil, while other combinations tolerate lime more successfully.

Heavy clay may suit pears where it remains structured and drains adequately. Permanently saturated or severely compacted soil restricts oxygen and weakens the root system.

Very dry, shallow soil can reduce shoot growth, fruit size and the formation of future flower buds.

Improve the wider planting area rather than filling a narrow hole with potting compost that differs greatly from the surrounding ground.

Planting and establishing a pear tree

Bare-root pear trees are planted during dormancy, generally from autumn until late winter, whenever the ground is neither frozen nor waterlogged.

Prepare a broad weed-free area and loosen compacted soil before planting.

Position the root collar correctly and keep the graft union clearly above the final soil level.

Spread bare roots naturally, backfill primarily with the original soil and water thoroughly to settle the ground around the roots.

Stake the tree where necessary, especially on quince rootstock or in an exposed position.

Keep a broad area free from grass and perennial weeds during establishment. Dense turf competes strongly for water and nutrients.

Water throughout the first growing season whenever rainfall is insufficient, not only during the first weeks after planting.

Which form of pear tree should you choose?

Pear trees may be supplied as maiden trees, low-stem trees, half standards or standards depending on cultivar, rootstock and availability.

A maiden tree allows the gardener to create a shape suited to the available space, including a bush, central leader, espalier, cordon or other trained form.

A low-stem tree keeps the crown and fruit within easier reach and is suitable for most gardens.

A half standard or standard provides clearance beneath the crown and suits a large garden, meadow or traditional orchard.

Pears respond particularly well to trained forms because their branches can be guided while young and their fruiting spurs can remain productive for several years.

The final form should be planned together with the rootstock. A very vigorous tree cannot be kept permanently compact simply through severe pruning.

How should a pear tree be pruned?

Young pear trees often grow strongly upright. Formative pruning should create a well-spaced framework before the branches become large and rigid.

Spreading or tying suitably positioned young branches towards a wider angle can reduce excessive vertical growth and encourage earlier fruiting.

Pears produce on short spurs and on younger branches depending on the cultivar and training system.

Severe pruning stimulates numerous upright water shoots and can delay cropping by returning the tree to vigorous vegetative growth.

On an established tree, remove dead, diseased, crossing and badly shaded branches while maintaining sufficient young and well-lit fruiting wood.

Summer pruning may be useful on trained trees to control vigorous shoots and expose fruiting spurs to light, but it should not remove so much foliage that fruit quality and tree reserves are reduced.

Fruit thinning and crop regularity

A pear tree may set more fruit than it can develop to a useful size.

Heavy crops produce small pears, bend branches and may reduce flower-bud formation for the following season.

After natural fruit drop, thin excessively dense clusters while retaining the best-positioned and healthiest fruit.

Thinning is particularly valuable on young trees, large-fruited cultivars and branches carrying several pears from one spur.

A moderate and regular harvest is preferable to alternating between branches overloaded with small fruit and a season with almost no crop.

Choose a cultivar suited to local disease pressure

Pear cultivars differ considerably in susceptibility to scab, canker, fire blight, pear rust and other diseases affecting foliage, fruit and wood.

A cultivar known to perform well in a comparable climate may be more useful than a famous variety that repeatedly develops cracked fruit, severe scab or damaged branches.

Heritage cultivars should not automatically be described as disease-resistant. Some are notably robust, while others require careful management in humid climates.

A sunny, ventilated position and an open crown help foliage and fruit dry after rain but do not replace cultivar resistance.

Remove dead wood, mummified fruit and severely diseased shoots, and avoid applying excessive nitrogen that produces soft and densely shaded growth.

Pear scab

Pear scab produces dark marks on leaves, young shoots and fruit.

Severe infections can distort pears, cause skin cracking and create entry points for secondary rots.

Susceptibility varies greatly between cultivars, and symptoms are favoured by prolonged leaf wetness during suitable temperatures.

A cultivar that remains relatively clean in one dry region may behave differently in a humid coastal or northern climate.

Maintaining an open crown, avoiding excessive vigour and selecting a suitably tolerant cultivar are particularly valuable where scab pressure is regularly high.

Canker, fire blight and wood diseases

Cankers may develop around wounds, damaged buds and frost injuries, causing localised bark death and progressive branch dieback.

Fire blight can affect flowers, young shoots and branches, producing rapid blackening and a characteristic hooked shoot tip in severe cases.

A blackened shoot is not automatically fire blight. Frost, canker and physical injury may produce similar symptoms, so unusual rapid dieback should be identified correctly.

Remove confirmed diseased wood using clean tools and avoid large unnecessary wounds.

Rootstock and cultivar susceptibility, tree vigour, weather and the presence of nearby susceptible plants all influence the level of risk.

Which pear tree should you choose?

For eating fresh, compare flavour, texture, ripening behaviour and storage life rather than fruit appearance alone.

For winter consumption, choose a genuine storage pear and make sure suitable cold conditions are available.

For cooking, choose a cultivar whose flesh and flavour improve with heat and whose harvest period suits the intended recipes.

For perry, compare sugar, acidity, tannins, juice yield and maturity rather than fresh-eating quality.

For a small garden, choose a cultivar compatible with a lower- or moderate-vigour rootstock and consider a low-stem or trained form.

For a traditional orchard, a vigorous pear rootstock, half standard or standard can produce a large and potentially long-lived tree.

For a humid climate, prioritise cultivars with useful tolerance of scab, canker and other locally important diseases.

For a reliable harvest, make sure that compatible pollen is available and combine cultivars with different picking and eating seasons.
