About

The quince (; Cydonia oblonga) is the sole member of the genus Cydonia in the Malinae subtribe (which contains apples, pears, and other fruits) of the Rosaceae family. It is a deciduous tree that bears hard, aromatic bright golden-yellow pome fruit, similar in appearance to a pear. Ripe quince fruits are hard, tart, and astringent. They are eaten raw or processed into jam, quince cheese, or alcoholic drinks.

The quince tree is sometimes grown as an ornamental plant for its attractive pale pink blossoms and as a miniature bonsai plant.

How to grow it

Quince is a hardy, drought-tolerant shrub which adapts to many soils of low to medium pH. It tolerates both shade and sun, but sunlight is required to produce larger flowers and ensure fruit ripening. It is a hardy plant that does not require much maintenance, and tolerates years without pruning or major insect and disease problems.

Quince is cultivated on all continents in warm-temperate and temperate climates. It requires a cooler period of the year, with temperatures under 7 °C (45 °F), to flower properly. Propagation is done by cuttings or layering; the former method produces better plants, but they take longer to mature than by the latter. Named cultivars are propagated by cuttings or layers grafted on quince rootstock. Propagation by seed is not used commercially. Quince forms thick bushes, which must be pruned and reduced into a single stem to grow fruit-bearing trees for commercial use. The tree is self-pollinated, but it produces better yields when cross-pollinated.
