How to Grow Haskap Berry
Lonicera caerulea
Haskap berries (honeyberries) are one of the earliest fruiting berries in the UK, often ripe by mid-June. Plant at least two different varieties for cross-pollination, spacing them about 1.2m apart in moist, well-drained soil. They are extraordinarily cold-hardy and need minimal care once established. Prune in late winter to remove old wood and keep the centre open for good airflow.
Yearly Lifecycle
Care Essentials
Early spring with a balanced fertiliser. Mulch with compost or bark.
Watch For
- Generally pest-free

☀️ Light
Full sun for best crops, tolerates partial shade
Full sun to partial shade. Haskaps tolerate some shade but produce the heaviest crops in full sun. Avoid very exposed, windy sites which can damage the early blossom.
💧 Watering
Consistently moist soil, mulch to retain moisture
Keep soil consistently moist, especially during fruit development. Haskaps have shallow roots and suffer in dry conditions. Mulch well to retain moisture.
🌱 Fertilizing
Balanced feed in early spring, annual compost mulch
Apply a balanced fertiliser in early spring. Mulch annually with garden compost or bark. Avoid excessive nitrogen which promotes leafy growth over fruit.
✂️ Pruning
Late winter pruning, remove oldest stems at base
Prune in late winter while dormant. Remove the oldest stems at the base and thin crowded growth to let light and air into the centre. Avoid heavy pruning on young bushes.
🍂 Mulching
Generous bark or compost mulch, top up annually
Mulch generously with bark or compost to keep the shallow roots cool and moist. Top up annually in spring.
Growing Tips
Pollination partners
Always plant at least two different haskap varieties — they need cross-pollination to fruit well. Check bloom times overlap when choosing pairs.
Harvest timing
Wait until berries are deep blue all the way through, not just on the skin. Taste-test a few — unripe berries are bitter.
Bird protection
Net bushes as fruit ripens — birds love haskaps. Drape netting over a frame rather than directly on branches to avoid trapping birds.
Winter pruning
Prune in late winter while dormant. Remove the oldest stems at the base and thin crowded growth to let light and air into the centre.
Pests & Diseases
Pest Birds
Identification: Missing or partially eaten berries. Bird droppings on and around bushes.
- Net bushes before fruit begins to colour, using a frame to keep netting off branches
- Use bird-scaring devices as a temporary deterrent
- No chemical treatment applicable
Pest Aphids
Identification: Clusters of green or black aphids on shoot tips. Leaves may curl slightly. Generally a minor problem.
- Blast off with a strong jet of water
- Encourage ladybirds and lacewings
- Usually self-limiting and rarely needs treatment
- Spray with a pyrethrin-based insecticide only if severe
Disease Powdery Mildew Podosphaera spp.
Symptoms: White powdery coating on leaves, usually appearing in late summer. Affected leaves may curl and brown at the edges.
Treatment: Remove badly affected leaves. Improve air circulation by thinning crowded growth.
Prevention: Prune to maintain an open bush with good airflow. Avoid drought stress. Water at the base.
Disease Leaf Blight Insolibasidium deformans
Symptoms: Brown spots on leaves that enlarge and merge, causing premature leaf drop. Worst in wet seasons.
Treatment: Remove and destroy affected leaves. Prune to improve air circulation.
Prevention: Ensure good spacing and airflow. Clear fallen leaves in autumn. Avoid overhead watering.
