Growing Cherries in Scotland: The Complete Guide

Prunus avium (sweet), Prunus cerasus (acid)

Acid and sweet cherries want genuinely different sites, not just different flavours, and a famous variety like Stella can let you down in a wet summer that a Morello wouldn't.

Cherries split into two real categories that behave differently, not one crop with two flavours. Sweet cherries want a warm, sunny wall. Acid cherries genuinely work in shade. The site you have available should decide which one you plant, not the other way round.

Choosing a rootstock

A cherry tree is a graftJoining a chosen fruiting variety onto a separate rootstock, so the tree grows the fruit of one plant on the roots of another. Full definition →: the rootstock controls its eventual size, not the variety or the tree's age. The size gap between cherries' two named rootstocksThe root system and lower stem a fruit tree is grafted onto, chosen to control the tree's eventual size rather than for its own fruit. Full definition → is unusually wide:

• Gisela 5: semi-dwarfingHow much a fruit tree's rootstock limits or allows its eventual size, from extremely dwarfing (smallest) through to very vigorous (largest). Full definition →, 3-4m. The smaller-garden option.
• Colt: semi-vigorous, 6-8m. A genuinely large tree, more than double Gisela 5's height.

Buy a tree already grafted onto the rootstock you want; it can't be changed later. For most gardens, Gisela 5 is the practical choice; Colt suits only a garden with real space to fill.

Choosing a site

Sweet cherries want a warm, sunny spot, ideally against a south- or south-west-facing wall. Acid cherries tolerate some shade and are suitable for a north-facing wall, a real option, not a fallback, if that's the only spare wall available. Soil should be deep, fertile and well-drained, ideally slightly acidic at pH 6.5-6.7, the narrowest sourced pH range of any fruit tree you're likely to grow.

Pollination

Acid cherries are self-fertileA plant that can set fruit using its own pollen, without needing a second, different variety nearby to cross-pollinate it. Full definition → as a rule. Among sweet varieties it's mixed: Stella and Lapins are self-fertile, while Kordia and Summer Sun genuinely need a pollination partnerA second, different variety of the same fruit planted nearby so the two can cross-pollinate each other, needed by any variety that isn't self-fertile. Full definition →. Check a specific variety before buying rather than assuming either way.

Planting

Choose a warm, sheltered location that isn't prone to late frosts. If planting into a lawn, clear a circle of grass at least 1m across first. For a fan-trainedA fruit tree or bush trained flat with branches radiating out from a low point, the standard shape for wall-grown stone fruit. Full definition → form, plant it 25-35cm out from the wall. Plant bare-root trees November to March while dormant; containerised trees any time of year. In a container, use a pot at least 45-50cm wide and deep with loam-based compost.

Care

Water newly planted trees regularly through dry spells for at least their first year. Once established, avoid overwatering in summer — it's a named cause of fruit splitting, especially in sweet varieties. Mulch in late winter or spring; a well-mulchedA layer of material spread over the soil around plants to suppress weeds, retain moisture, and improve soil structure as it breaks down. Full definition → tree generally needs no extra feeding. Container trees need a steady supply of moisture through the growing season plus a high-potassium liquid feed every fortnight from April to August.

Pruning and training forms

The same reversed rule as plums and damsons applies here too, all three sharing the Prunus family: never prune while dormant. Prune annually as soon as harvest finishes, usually late July or August; prune young trees in spring instead. A cut made over winter risks silver leaf disease and bacterial canker.

• Bush: small, open-centredA bush pruned with an open middle and outward-radiating branches, so light and air reach every part rather than a dense, shaded centre. Full definition →, the standard free-standing shape.
• Pyramid: larger, with the central leaderTwo more fruit tree shapes: central leader keeps one dominant upright trunk; half-standard is a free-standing tree on a clear trunk of about 1.2–1.5m. Full definition → kept intact.
• Fan: trained flat against a wall or fence; the form that lets sweet cherries be netted against birds and lets acid cherries make use of a shaded wall.

Varieties

6 AGMThe RHS's Award of Garden Merit: a UK-wide trials award for reliable performance, not a Scotland-specific recommendation. Full definition → cherry varieties, split across sweet and acid types. Morello is the only acid cherry on the list and self-fertile by default; the sweet varieties split between self-fertile (Stella, Lapins, Sweetheart) and needing a partner (Kordia, Summer Sun).

Sweetheart (sweet, self-fertile, August harvest) and Summer Sun and Kordia (sweet, not self-fertile, July-August) round out the list. Only Morello and Stella have a confirmed site-suitability or weather-risk trait; the other three simply haven't been checked for one.

Harvesting

Cherries ripen from early summer onwards, starting late July for the earliest varieties, depending on type. Pick during dry weather where possible, and hold the stalk rather than the fruit, which bruises easily — cutting whole bunches free with stalks intact works well too, rather than pulling individual cherries.

Not every cherry on a tree ripens at once, so expect to check back over several days rather than stripping the whole crop in one go. There's no dedicated storage advice for cherries the way there is for some other fruit, so treat a picked batch as something to eat, cook or freeze promptly rather than something that keeps well in a bowl.

Common problems

• Fruit aphids distort new growth and shoots.
• Brown rot and blossom wilt both affect fruit and flowers, spreading fast in damp conditions.
• Birds strip ripening cherries fast; net fan-trained trees or move potted trees somewhere protected as fruit colours up.
