How to Grow Bilberry
Vaccinium myrtillus
Bilberry needs acidic, peaty soil (pH 4.5–6) and full sun to partial shade. It is extremely hardy and suits moorland-style conditions. Amend heavy or neutral soils with ericaceous compost before planting. Plant in groups of three or more for best yields. Water consistently in dry spells, especially in the first two seasons. Prune lightly in late winter to remove dead wood. Harvest the intensely flavoured dark berries in July–August.
Yearly Lifecycle
Care Essentials
Early spring with an ericaceous (acid-loving) fertiliser. Mulch with pine bark or composted bracken to maintain acidity and moisture.
Watch For
- Birds (net during ripening)
- Vine weevil
- Botrytis (grey mould) in wet summers
- Chlorosis from alkaline soil
Care Requirements
Light
Full sun to partial shade
Thrives in full sun on open moorland and heathland, but tolerates partial shade under light tree cover. Avoid deep shade, which reduces fruiting.
Watering
Consistent moisture; avoid waterlogging
Keep soil evenly moist, especially during fruit development. Bilberry tolerates peaty, damp conditions but not prolonged waterlogging. Water in dry spells during establishment.
Fertilizing
Ericaceous feed in spring
Apply an ericaceous (acid-loving plant) fertiliser in early spring as growth resumes. Avoid general-purpose feeds — they raise soil pH. Mulch annually with pine bark or composted bracken.
Pruning
Light pruning in late winter
Remove dead or very old stems at the base in late winter or early spring. Do not hard prune — bilberries fruit on the previous year's wood. Young plants need minimal pruning; established plants benefit from occasional renewal cuts.
Spacing
60 cm apart in groups
Space plants 60 cm apart in groups of three or more. Bilberries spread slowly by rhizomes and form colonies over time. Closer planting speeds ground cover.
