Soil & Growing Conditions

Water: Prefers moist soil (PFAF)

Soil pH range

4.5 6

Span reflects genuine variation between the cited authorities, not a single agreed figure.

Growth Stages

Stage	BBCH	Notes
Planting and establishment	0	Propagate by semi-hardwood cuttings mid-late summer or by layering (RHS); PFAF adds seed (3 months cold stratification) or sucker division in spring/early autumn as alternatives. Needs moist, free-draining, lime-free acidic soil -- becomes chlorotic in alkaline conditions (RHS; PFAF).
Vegetative spread	3	Forms a dense, prostrate, spreading carpet -- RHS records up to 1-1.5m spread from a 0.1-0.5m tall plant (PFAF gives a closer 1m spread on a 0.3m plant). Full sun gives the best fruiting, though light or partial shade is tolerated (RHS; PFAF).
Flowering	6	White, bell-shaped flowers (RHS); PFAF records flowering May-June.
Fruiting and harvest	8	Tart red fruit ripens July-August (RHS); PFAF records seed ripening extending into October.

Harvest & Storage

When to pick: Tart red fruit ripens July-August (RHS). Used much like cranberries in preserves, given its acid flavour (PFAF).

Diseases

Lime-induced chlorosis

moderate

Both RHS and PFAF independently confirm this acid-loving plant becomes chlorotic in alkaline/lime-containing soil; the same abiotic issue already documented for Cranberry.

Powdery mildew

low

Named directly on RHS's own growing-guide page as "powdery mildews" (no severity grading given).

Foot and root rot (general)

low

Named directly on RHS's own growing-guide page as "root rot".

Honey fungus

low

Armillaria spp.

Named directly on RHS's own growing-guide page; RHS states this rarely affects the crop, and PFAF separately states the genus is notably resistant to honey fungus -- compatible, low-risk descriptions from two sources.

1. Plants For A Future (PFAF) - Vaccinium vitis-idaea (cowberry, lingonberry)

   Evergreen, USDA zones 3-8, UK zone 5. Flowers May-June, seed ripens August-October. Size 0.3m x 1m, dense prostrate carpet. Soil: moist but freely-draining, lime-free, pH 4.5-6, light loamy with leaf-mould/peat preferred, chlorotic in alkaline soil. Full sun or light shade, fruits better in sun. Propagation: seed (3mo cold stratification), half-ripe cuttings August (slow/difficult), layering (18mo), sucker division. Genus notably resistant to honey fungus. Native to Europe, north Asia to Japan, North America. Edible: fruit raw/cooked, acid flavour, used like cranberries in preserves; leaves for tea but contain arbutin, not for regular use. Medicinal: leaves antiseptic/astringent/diuretic, traditionally used for arthritis, rheumatism, diabetes, diarrhoea, sore throats. Yellow dye from leaves/stems, purple dye from fruit, ground cover use.

2. Royal Horticultural Society - Vaccinium vitis-idaea (cowberry)

   Evergreen, dwarf creeping/spreading habit, 10-20yrs to maturity. Hardiness H6 (-20 to -15C). Soil: loam/sand, acidic, moist but well-drained. Full sun to partial shade, south/west-facing, tolerates exposed or sheltered. Height 0.1-0.5m, spread 1-1.5m. Propagate by semi-hardwood cuttings mid-late summer, layering mid-summer, or seed in cold frame autumn. Pests/diseases: generally pest-free; honey fungus (rarely), powdery mildews, root rot, chlorosis from iron/manganese deficiency. Native to GB/Ireland and Europe. White bell-shaped flowers, tart red fruit July-August. Family Ericaceae.
