Loquat

Loquat is grown mainly for its early-season fresh fruit, prized for arriving before most other tree fruits, and also for preserves, syrups, and other products. Trees are grown commercially in orchards and very widely as ornamental and backyard trees for their attractive evergreen foliage and fruit.

Because the fruit ripens in clusters and is delicate, fruit thinning and careful handling are used to improve size and quality for the fresh market.

Family

Rosaceae (rose family)

Genus and species

Eriobotrya japonica

Growth habit

Small to medium evergreen tree with large, leathery leaves, bearing pome fruit in clusters

Relatives

A pome fruit related to apple, pear, and quince within the rose family

Loquat is native to south-central China and has been cultivated in China and Japan for a very long time. It has since spread to subtropical and mild-temperate regions worldwide, including the Mediterranean basin, South Asia, and the Americas.

Loquat is adapted to subtropical and mild-temperate climates. The tree itself is fairly cold-hardy, but because it flowers in autumn or early winter and carries young fruit through winter, its flowers and developing fruit are vulnerable to frost, which is the main climatic limitation on cropping.

Mild winters and warm springs favor good fruit set and early ripening, while hot, dry conditions during fruit development can reduce quality.

Loquat grows on a range of soils but does best on deep, fertile, well-drained loams. Good drainage is essential, as the tree is sensitive to waterlogging, which promotes root problems.

Loquat is grown from seed for rootstocks and ornamentals, while selected fruiting cultivars are propagated by grafting to reproduce their fruit quality and shorten the time to bearing. Fruit thinning, pruning, and, in frost-prone areas, protection of the developing fruit are important management practices.

• Grafted cultivars used to propagate selected fruiting types true to type
• Fruit thinning to improve fruit size and quality for the fresh market
• Pruning to maintain an open, manageable canopy and remove damaged wood
• Frost protection of autumn-winter flowers and developing fruit where feasible

Loquat responds to balanced nutrition, with nitrogen supporting growth and potassium contributing to fruit development and quality. Excessive vigor can delay bearing and increase disease susceptibility, so nutrition is balanced against tree vigor.

Loquat benefits from adequate, regular moisture during fruit development in late winter and spring, and irrigation is used in areas with dry springs. Good drainage is maintained to avoid waterlogging, and consistent moisture supports fruit size and reduces splitting.

Fire blight, a bacterial disease of the rose family, can seriously affect loquat, killing blossoms and shoots, and loquat scab and anthracnose blemish leaves and fruit. Root and collar rots occur on poorly drained soils.

Fruit flies attack the ripening fruit, and aphids, scale insects, and birds also cause damage. Management combines sanitation, removal of blighted wood, fruit protection such as bagging in some systems, and, where warranted, locally authorized controls applied according to their labels.

Loquat is harvested by hand when the fruit is fully colored and ripe, since it does not improve in sweetness after picking. The delicate fruit bruises easily and has a short shelf life, so it is picked carefully, often with the stalk attached, and marketed promptly.

• Fresh fruit valued as one of the earliest tree fruits of the season
• Preserves, jams, syrups, and jellies made from the fruit
• Use in juices, desserts, and, in some regions, traditional preparations
• Ornamental use of the evergreen tree in gardens and landscapes
