How to Grow Griselinia
Griselinia littoralis
Griselinia is a superb coastal hedging plant with glossy apple-green leaves that look fresh year-round. It thrives in mild, maritime climates and tolerates salt spray and wind. Plant in well-drained soil — it dislikes waterlogging. Not fully hardy inland; in cold areas, plant against a sheltered wall or choose a hardier alternative. Trim hedges in late spring and again in late summer.
Yearly Lifecycle
Care Essentials
Mulch with compost in spring. Hedging plants benefit from a balanced feed in April.
Watch For
- Frost damage in cold inland areas
- Leaf spot in wet conditions
- Root rot in waterlogged soil

☀️ Light
Full sun to partial shade
Thrives in full sun or partial shade. In deep shade the foliage becomes pale and growth is weak.
💧 Watering
Moderate; avoid waterlogging
Water regularly during establishment (first 1-2 years). Once established, griselinia tolerates some drought but dislikes prolonged dry spells in summer.
🌱 Fertilizing
Balanced feed in April, compost mulch in spring
Hedging plants benefit from a balanced granular feed in April followed by a compost mulch. This replaces nutrients lost through regular trimming.
✂️ Pruning
Twice yearly — late May and August
Trim in late May after the spring growth flush and again in August. Avoid autumn pruning as soft new growth is vulnerable to frost damage.
❄️ Overwintering
Mild areas only; protect from hard frost
Griselinia is not fully hardy in cold inland UK areas. Protect young or recently planted specimens with fleece during severe frost. Established coastal plants are generally fine.
Growing Tips
Ideal for coastal hedging
Griselinia is one of the best hedging plants for coastal gardens, tolerating salt spray and strong winds better than most alternatives. It is less suitable for cold inland areas.
Avoid cold inland positions
In the UK, griselinia is not fully hardy inland. In areas prone to hard frosts, plant against a sheltered south or west-facing wall, or choose a hardier hedging plant instead.
Prune twice, not once
Two trims per year — late May and August — keeps hedges dense and neat. Pruning only once produces a looser, less formal shape and encourages more vigorous growth.
Feed hedges regularly
Hedging plants are regularly stripped of leaf material (and its nutrients) when trimmed. A balanced feed in April and a thick compost mulch maintains vigour over time.
Pests & Diseases
Pest Aphid
Identification: Clusters of small insects on soft new shoot tips in spring and early summer.
- Blast off with a jet of water.
- Apply insecticidal soap.
- Pyrethrum contact spray.
Pest Vine Weevil
Identification: Notched leaf margins from adult feeding at night; C-shaped grubs in the root zone causing wilting.
- Apply Steinernema kraussei nematodes to moist soil in autumn.
- Imidacloprid drench for container-grown plants.
Pest Scale Insect
Identification: Brown or white waxy bumps on stems; sticky honeydew and sooty mould on lower leaves.
- Scrub off with soapy water and a soft brush.
- Apply horticultural oil in late winter.
- Systemic insecticide containing thiacloprid.
Disease Leaf Spot Pseudomonas syringae / Phoma spp.
Symptoms: Dark brown or black spots on leaves, often with a yellow halo. Most common in wet summers.
Treatment: Remove and dispose of affected leaves. Improve air circulation by not over-crowding.
Prevention: Avoid overhead irrigation. Ensure good spacing and air flow through the hedge.
Disease Honey Fungus Armillaria mellea
Symptoms: Sudden dieback of sections of hedge; white fungal sheets under bark at the base; honey-coloured toadstools in autumn.
Treatment: No cure. Remove all infected material including as many roots as possible. Do not replant with susceptible species.
Prevention: Avoid planting near old tree stumps. Keep plants healthy and well-fed to resist infection.
