How to Grow Sea Buckthorn
Hippophae rhamnoides
Sea buckthorn is an extremely hardy, nitrogen-fixing shrub that thrives in poor soil and exposed coastal sites across the UK. You need both a male and a female plant within 15m for wind pollination and fruit production. The bright orange berries are exceptionally nutritious but very difficult to pick — the best method is to freeze branches then shake off the berries. Plant in full sun, avoid rich feeds which encourage excessive suckering, and install a root barrier as it spreads vigorously by suckers.

☀️ Light
Full sun essential, thrives in exposed sites
Full sun is essential for fruiting. Extremely tolerant of exposed, coastal, and windy sites. Avoid shade.
💧 Watering
Very drought-tolerant once established
Very drought-tolerant once established. Rarely needs watering except in the first year after planting.
🌱 Fertilizing
Rarely needed, fixes own nitrogen
Rarely needed — thrives in poor soil and fixes its own nitrogen. Avoid rich feeds which encourage excessive suckering.
✂️ Pruning
Late winter prune, control suckers, wear gloves
Prune in late winter. Remove dead wood and unwanted suckers. Wear thick gloves as stems are very thorny. Contain spread with a root barrier.
🍎 Harvesting
Freeze branches then shake off berries
Berries ripen August to September. Very difficult to pick individually — freeze branches then shake off berries, or snip whole clusters.
Growing Tips
Need male and female
Plant at least one male within 15m of female plants for wind pollination — without a male, you won't get berries.
Freeze then shake
Freeze harvested branches then shake off the berries — picking them individually is nearly impossible due to thorns.
Contain the suckers
Install a root barrier at planting to contain vigorous suckering; sea buckthorn spreads aggressively if unchecked.
Wear thick gloves
Wear thick gloves when pruning or harvesting — the thorns are vicious and can cause painful wounds.
Pests & Diseases
Pest Scale Insects
Identification: Small brown or grey waxy bumps on stems and branches; sticky honeydew and sooty mould
- Scrub off with a soft brush dipped in soapy water during winter
- Encourage ladybirds and parasitic wasps
- Plant oil-based winter wash applied to dormant stems
Pest Aphids
Identification: Clusters of small green insects on young shoot tips; minor leaf curling
- Blast off with water — plants are robust enough to tolerate this
- Encourage natural predators
- Rarely needed; fatty acid spray if severe
Disease Verticillium Wilt Verticillium dahliae
Symptoms: Wilting and yellowing of leaves on individual branches; progressive dieback; brown streaking in wood when cut
Treatment: Prune out and destroy affected branches well below visible symptoms. Sterilise tools between cuts.
Prevention: Plant in well-drained soil. Avoid planting where susceptible crops (potatoes, tomatoes) have grown.
Disease Sea Buckthorn Scab Stigmina hippophaes
Symptoms: Dark spots on berries and leaves; fruit may crack or shrivel; reduced harvest quality
Treatment: Prune out affected growth. Improve air circulation within the canopy.
Prevention: Thin branches to improve airflow. Remove fallen debris. Choose resistant cultivars.
