How to Grow Portuguese Laurel
Prunus lusitanica
Portuguese laurel is a refined alternative to common cherry laurel, with smaller, darker leaves on distinctive red stalks. It makes an elegant formal hedge or can be trained as a standard tree. More tolerant of chalk, shade, and hard pruning than cherry laurel. Fragrant white flower racemes in June attract pollinators, followed by dark purple berries. Slower-growing than cherry laurel but ultimately more manageable and attractive. Hardy throughout the UK.
Yearly Lifecycle
Care Essentials
Mulch with compost in spring. Hedging plants benefit from a balanced feed in April to maintain dense growth.
Watch For
- Powdery mildew in dry conditions
- Shot hole disease
- Cherry slug sawfly larvae on leaves

☀️ Light
Full sun to partial shade
Portuguese laurel tolerates more shade than most hedging plants, making it useful for north-facing aspects and under tree canopy. For densest growth and best flowering, site in full sun.
💧 Watering
Low once established — water young plants in dry spells
Established plants are drought-tolerant and rarely need watering. In the first two years after planting, water during dry periods to help the root system establish.
🌱 Fertilizing
Light spring feed for hedging; established specimens need little
A balanced granular fertiliser along the hedge line in April helps maintain dense growth on regularly pruned hedges. Freestanding specimens on reasonable soil need no routine feeding.
✂️ Pruning
Once or twice in summer using secateurs, not hedge trimmers
Prune between May and July to shape. A second light trim in September tidies autumn growth on formal hedges. Always use secateurs — hedge trimmers shred the large leaves and leave unsightly brown edges.
❄️ Overwintering
Fully hardy throughout the UK — no protection needed
Portuguese laurel is reliably hardy to at least -15°C and requires no winter protection anywhere in the UK. Even young plants established in autumn will survive without fleece or other covering.
Growing Tips
Use secateurs, not hedge trimmers
Hedge trimmers shred the large leaves, leaving brown ragged edges that persist all season. Always use sharp secateurs or loppers for a clean cut.
Slower but more manageable than cherry laurel
Portuguese laurel grows at roughly half the rate of cherry laurel, which means less frequent pruning and a neater result with far less maintenance over time.
Excellent for chalk gardens
Unlike cherry laurel, Portuguese laurel thrives in alkaline chalk soils where many hedging plants struggle. No soil acidification needed.
Can be trained as a standard or cloud-pruned specimen
With patience, Portuguese laurel responds beautifully to topiary and cloud pruning. Its small leaves and strong framework make it ideal for formal or artistic shapes.
Pests & Diseases
Pest Cherry Slug Sawfly
Identification: Shiny, dark olive-green slug-like larvae on the upper leaf surface, skeletonising leaves and leaving a papery brown layer behind.
- Dust affected leaves with fine wood ash or kaolin clay to desiccate larvae.
- Knock larvae off with a strong jet of water and crush on the ground.
- Spray with pyrethrin-based insecticide as a contact treatment when larvae are present.
Pest Vine Weevil
Identification: Irregular notches eaten from leaf margins by adult beetles at night; C-shaped creamy-white grubs in the rootball cause wilting and plant collapse.
- Apply pathogenic nematodes (Steinernema kraussei) to moist soil in August-October to target grubs.
- Check rootball when repotting and hand-pick any grubs found.
- Apply an imidacloprid or acetamiprid drench to the rootball in spring or autumn.
Pest Leaf-Mining Moth
Identification: Brown blotch mines inside leaves, visible as pale irregular patches when held to light; the mine enlarges as the larva feeds.
- Remove and destroy mined leaves promptly to break the cycle.
- Encourage natural predators such as tits and other insectivorous birds.
- Systemic insecticides are rarely justified for ornamental hedging — control is usually cosmetic only.
Disease Shot Hole Disease Stigmina carpophila
Symptoms: Small brown circular spots on leaves that fall out, leaving neat round holes as if the leaf were shot through. Affected leaves may yellow and drop.
Treatment: Remove and dispose of affected leaves and fallen debris. Apply a copper-based fungicide in spring before new growth and again in autumn.
Prevention: Ensure good air circulation within the hedge. Avoid wetting foliage when watering. Prune in dry weather.
Disease Powdery Mildew Podosphaera pannosa
Symptoms: White powdery coating on young leaves and shoots, typically in late summer. Affected growth may be distorted or stunted.
Treatment: Remove badly affected shoots. Apply a sulphur-based or potassium bicarbonate fungicide at first sign.
Prevention: Avoid planting in dry, poorly ventilated spots. Water at the base and mulch to maintain soil moisture. Do not over-feed with high-nitrogen fertiliser.
