Quince

Thrives in USDA Zones 5 - 9

• Transplant

  Plant bare-root or container trees in late autumn to early spring while dormant

• Harvest

  Harvest when fruit has turned from green to yellow and developed a strong fragrance; a gentle tap should produce a hollow sound. Fruit should be firm - unlike most fruits, quince does not soften at harvest

• Apply compost around the drip line each spring; quince is a light feeder compared to apples and pears - avoid high-nitrogen fertilisers that encourage soft growth susceptible to fire blight.

• Prune for an open vase shape to maximise airflow and reduce fungal disease pressure; remove crossing branches annually.

• Copper-based sprays applied at early bloom and repeated through wet springs significantly reduce fire blight and quince leaf blight infections.

• Harvest before the first hard frost; quince stores for 2-3 months in a cool cellar and improves in fragrance off the tree.

• Watering

  If dry weather lingers, let the top 2 inches start to dry before watering again. This plant often responds better to an occasional deep soak than to frequent light watering.

• Feeding

  Extra feeding is rarely required if soil is healthy. If growth looks pale or slow, a light compost top-dressing is often enough before adding anything stronger.

• Pruning

  If pruning is needed, dormancy or the period just after harvest is often the simplest window. Dead, damaged, or crossing growth is usually the first place to start.

• Seasonal care

  In late fall, a light cleanup and fresh mulch can help if winter protection is useful in your climate. Leaving a little space around crowns and trunks often helps air move and keeps excess moisture from sitting there.

• Pineapple

  The most popular American variety; large, round fruit with excellent pineapple-like flavour when cooked. Relatively early-ripening.

  Best for

  Jelly, preserves, baking; most widely available

• Aromatnaya

  Rare Russian variety that can be eaten raw when fully ripe; sweet with only mild astringency. A novelty for those wanting fresh quince.

  Best for

  Fresh eating; unique in the genus for raw palatability

• Champion

  Very large fruit with excellent cooking quality and intense flavour; later-ripening than Pineapple. Good disease resistance.

  Best for

  Cooking; heavy crops

• Smyrna

  Old Mediterranean variety with large lemon-yellow fruit and classic quince flavour; widely grown commercially in the Middle East and Europe for membrillo paste.

  Best for

  Traditional quince paste (membrillo); cooking

• Vranja

  Serbian heirloom with very large, pear-shaped fruit and exceptional fragrance; one of the best ornamental quinces for garden use.

  Best for

  Ornamental value; cooking; zones 5-9

• Quince Leaf Blight
• Codling Moth
• Aphids
• Fire Blight
• Brown Rot

Origin

Native to the Caucasus region and northern Iran; wild populations persist in mountain forests of Georgia, Armenia, and Iran, where the species has been cultivated for over 4,000 years.

Native Habitat

Rocky slopes, forest edges, and riverbanks in the Caucasus and northern Middle East at elevations up to 1,200 meters.

Current Distribution

Cultivated across the temperate world; primary commercial production in Turkey, China, Argentina, Iran, and Morocco. Frequently naturalised near old homesteads in North America and Europe.

Rose family (Rosaceae)

Genus

Cydonia

Species

Cydonia oblonga

• Root System

  Spreading, moderately deep root system; more tolerant of wet or heavy soils than apple and pear. Roots sucker occasionally from the base.

• Stem

  Small, somewhat crooked deciduous tree or large shrub typically reaching 12-20 feet with a graceful, gnarled character that increases with age. Bark becomes deeply furrowed on old specimens.

• Leaves

  Ovate, dark green leaves with a woolly white underside that persists through the growing season; leaves turn yellow-orange in autumn before dropping.

• Flowers

  Large, solitary, 5-petaled flowers in soft pink and white at the stem tips in spring, after leaves emerge; among the most beautiful of orchard flowers. Flowers are self-fertile and attract early bees.

• Fruit

  Large, irregular pear or apple-shaped fruit with a thick, bumpy golden-yellow skin and a downy surface when young; intensely fragrant at maturity. Flesh is hard, white, and astringent raw but turns rose-pink and tender when cooked, with a complex floral-quince aroma.

Quince is the only species in its genus and one of the oldest cultivated fruits in the world, with archaeological evidence of cultivation in the Caucasus and Middle East dating back over 4,000 years. The ancient Greeks regarded it as a sacred fruit associated with love, marriage, and Aphrodite; Homer's Odyssey and other classical texts mention quince, and Greek brides customarily ate a quince before their wedding night as a ritual preparation. Roman orchardists grew quince extensively, and Pliny the Elder described multiple varieties. The Roman cookbook Apicius includes quince preserves and wine. In medieval Europe, quince marmalade - the original marmalade, from the Portuguese marmelo, meaning quince - was a luxury confection traded across the continent. Modern orange marmalade only acquired the name in the 17th-18th century as quince was gradually displaced by cheaper citrus. The Japanese quince (Chaenomeles japonica) is a related ornamental shrub grown for its spring flowers, not the same plant as fruiting quince.

Quince has a long history in Mediterranean, Middle Eastern, and European folk medicine, primarily used for digestive ailments, sore throats, and as a general tonic. Its high pectin content gave it a practical role in traditional medicine as a binding agent.

• Ancient Greek and Roman use - Fruit and seeds

  Greek and Roman physicians including Dioscorides and Galen recommended quince for gastric disorders, diarrhoea, and as a digestive aid. The high pectin and tannin content of quince fruit likely gave these preparations real efficacy as astringents. Quince seed mucilage, extracted by soaking seeds in water, was used as a topical soothing agent for sore throats and skin irritation.

• Persian and Islamic medical tradition - Fruit and juice

  Ibn Sina (Avicenna) praised quince extensively in the Canon of Medicine for its toning effect on the stomach and heart, recommending it for nausea, vomiting, and as a general strengthening food. Persian medical texts considered quince a "warm" food that balanced "cold" digestive constitutions. Quince syrup (rob-e beh in Persian) remains a traditional remedy for gastrointestinal discomfort across the Middle East.

Quince fruit and seeds are safe in normal culinary quantities. Quince seeds contain small amounts of amygdalin (as do apple seeds) and should not be consumed in large quantities or used as an extract; they are safe as part of the whole fruit in normal cooking contexts.
