Brown spots are typically caused by Quince Leaf Blight, a fungal disease that thrives in warm, wet summers. This condition can cause premature leaf drop and may spot the fruit itself. To manage it, remove and destroy fallen leaves in autumn and prune the tree to improve air circulation.

Pruning should be done in winter when the tree is dormant to remove dead, diseased, or crossing branches. Because quinces fruit on the tips of the previous year's growth, you should avoid shortening all new shoots. Aim to maintain an open centre to allow light and air to reach the fruit.

Quince trees thrive in deep, moisture-retentive, and slightly acidic loamy soils. They struggle in dry, sandy soils or shallow chalky ground, which can cause poor growth and low fruit yield. Mulching with organic matter helps retain the moisture these trees need.

Quinces usually ripen in late October or early November, turning from green to a rich golden yellow. They should be left on the tree as long as possible to develop their strong aroma but harvested before the first severe frosts. Once picked, they can be stored in a cool, dark place for several weeks.

A standard bush quince tree typically reaches a height and spread of 3 to 4 metres. You can restrict the size for smaller gardens by choosing a tree grafted onto a semi-dwarfing rootstock like Quince C. Regular winter pruning also helps control the shape and size of the canopy.

Quince fruit is generally too hard, tart, and astringent to be eaten raw. The fruit must be cooked to break down its tough flesh and release its sweet, aromatic flavour. It is traditionally used for making jams, jellies, and fruit pastes like membrillo.

Most modern quince varieties grown in the UK are self-fertile, meaning a single tree can produce fruit without a pollination partner. However, planting a second tree often improves the yield through cross-pollination. Always check the specific variety label to confirm if it requires a partner.

The ideal time to plant bare-rootquince trees is between November and March while the tree is dormant. Pot-grown trees can be planted at any time of the year, provided the ground is not frozen or waterlogged. Ensure you water the tree regularly during its first dry season to help it establish.
