Plum Quetsche D'Alsace 15 Litre Pot Half Standard

Plum (Prunus domestica 'Quetsche D'Alsace') – A Classic Alsatian Damson-Type Plum for Reliable Crops & Ornamental Garden Trees

Prunus domestica 'Quetsche D'Alsace' is a traditional European plum of long-standing reputation, prized for generations in the orchards of Alsace and beyond for its generous crops of richly flavoured, deep blue-purple fruit. A handsome, moderately vigorous deciduous tree, it brings both productive value and seasonal beauty to the garden — clouds of white blossom in spring giving way to lush summer foliage and, in late summer to early autumn, heavy clusters of oval, freestone plums with sweet, fragrant, amber-yellow flesh.

Well-suited to UK conditions, this variety is reliably hardy and self-fertile, meaning a single tree will crop without the need for a pollination partner. Whether planted as a freestanding standard in a lawn, trained against a sunny wall, or incorporated into a productive kitchen garden, 'Quetsche D'Alsace' is a rewarding and long-lived choice for gardeners seeking both ornament and harvest.

Key Features

• Traditional Alsatian plum variety with a long heritage of reliable, heavy cropping

• Deep blue-purple, oval freestone fruit with sweet, fragrant amber flesh — excellent fresh or for preserves, tarts, and eau-de-vie

• Self-fertile — crops well without a pollination partner

• Attractive white blossom in spring and good ornamental character throughout the seasons

• Reliably hardy and adaptable to a wide range of UK growing conditions

Growing Conditions

Position: 'Quetsche D'Alsace' performs best in full sun — a warm, open, sheltered site will encourage the finest fruit set and ripening. It will tolerate partial shade but cropping may be reduced. Avoid frost pockets where possible, as late spring frosts can damage the early blossom and diminish the harvest. A south- or west-facing aspect is ideal, and the tree responds particularly well when trained against a warm wall.

Soil: Best suited to a deep, fertile, moisture-retentive but well-drained loam. It will grow in a range of soil types, including clay and chalky soils, provided drainage is reasonable — plums dislike sitting in waterlogged ground, which can cause root problems and increase susceptibility to disease. Slightly alkaline to neutral soils (pH 6.5–7.5) are ideal. Enrich poorer soils with well-rotted organic matter before planting.

Hardiness: Fully hardy throughout the UK, tolerating typical winter temperatures without difficulty. The main vulnerability lies with late spring frosts coinciding with blossom — in colder or more exposed gardens, some frost protection at flowering time is beneficial.

Habit & Appearance

Foliage: The leaves are broadly oval, mid- to deep green, with a slightly matt surface texture, providing a lush, full canopy through the growing season. Autumn brings a pleasing turn of yellow before leaf fall, giving a final flush of seasonal colour before the tree enters its winter dormancy.

Flowers: In mid-spring, the bare branches are covered in clusters of delicate, five-petalled white flowers — an attractive and welcome sight early in the season, and an important early nectar source for bees and other pollinating insects.

Fruit: The plums ripen in late summer to early autumn, typically August into September. The fruit is oval, medium-sized, with a distinctive deep blue to purple-black skin and a natural waxy bloom. The flesh is sweet, juicy, and freestone — separating cleanly from the stone — making it ideal for eating fresh, cooking, bottling, making jam, or distilling in the traditional Alsatian fashion.

Ultimate Size: On a standard rootstock, this variety will develop into a medium-sized deciduous tree. Growth rate is moderate, and ultimate size will vary depending on rootstock selection — trees on semi-dwarfing rootstocks such as St. Julien A are more compact and easier to manage in smaller gardens, while those on more vigorous rootstocks will develop into larger, long-lived orchard trees.

Care & Pruning

Watering: Water regularly and thoroughly during the first two growing seasons to support strong establishment. Once settled, the tree is largely self-sufficient in normal UK rainfall, though during prolonged dry spells in summer — particularly when fruit is swelling — additional irrigation will help prevent premature fruit drop and improve crop size and quality.

Feeding: Apply a balanced general-purpose fertiliser or a dedicated fruit tree feed in early spring as growth begins. An annual mulch of well-rotted organic matter or garden compost around the base — keeping it clear of the trunk — will help retain soil moisture, suppress competing weeds, and steadily improve soil fertility over time.

Pruning: Plums should always be pruned during the active growing season — late spring through to late summer — to minimise the risk of silver leaf disease, which can enter through pruning wounds made during dormancy. When establishing a young tree, aim to build an open, balanced framework of main branches. Once established, routine pruning involves the removal of dead, diseased, damaged, or crossing branches, and the thinning of congested growth to maintain good light and air circulation through the canopy. Avoid heavy pruning in any single season — little and
