Please check settings. My Japanese Quince bushes are covered with aphids and ants. How can this be controlled? I hear that banana peels buried in the ground repels aphids. Please help! The ants are attracted to the excrement left by the aphids; once the aphids are gone, the ants will lose interest.
For a serious aphid infestation, start by washing the leaves of the plant with a strong stream of water. In Jane's grandmother's time the quince tree Cydonia oblonga was among our popular trees.
And thankfully they have returned to fashion. Trendy chefs, restaurateurs and really good cooks love using quinces. It's a deciduous tree and a tough one. It will grow virtually anywhere throughout the country, as long as its in a sunny spot with well drained soil. The tree grows to about 7 metres high, and is approximately 2 metres wide, but it should be pruned to keep a more compact shape.

Quince trees Cydonia oblonga come in many shapes and sizes, to suit all gardens. You can choose from large spreading trees that would make an attractive specimen in a lawn, to half standards that are suitable for smaller gardens or even in pots. Free-standing trees reach a height and spread of 3. They are self-fertile and usually start cropping when five or six years old.
Quinces are often confused with the shrub Chaenomeles Japanese quince , the fruit of which is also edible. Quinces tolerate a range of soils, but grow best in a deep, fertile, moisture-retentive soil. They grow particularly well when planted near a pond or stream, but dislike waterlogging in winter. In light or shallow chalky soils, add plenty of organic matter before planting and mulch well afterwards.
Although they are hardy, quinces need a warm, sunny, sheltered spot, as the flowers open early so are susceptible to frost, and sun is needed for the fruit to ripen. Avoid planting in frost-prone positions.
In southern England or in mild coastal or urban sites they can be grown in the open. But further north or in colder or exposed sites, they are best planted in a sheltered spot, for example against a south- or south-west-facing wall.
As alternative to growing in the ground, compact forms are happy in large containers filled with soil-based compost. A 45cm 18in container is the smallest feasible, and 60cm 2ft would be ideal. Plant new quince trees between November and March, while they are dormant. If planting more than one, bush trees should be spaced about 3. Stake trees for the first three or four years. See our step-by-step guides for full planting details:.
Many of the insect pests that attack apples or pears, including codling moth and winter moth caterpillars also attack quinces, but are seldom significant problems. Quince leaf blight is usually the only disease that can be troublesome, but others may occur, such as powdery mildew, brown rot and fireblight.
