How to grow laurustinus
Overview
Laurustinus (Viburnum tinus) is a dense, evergreen shrub valued for its dark green foliage and clusters of pinkish-white flowers in late winter to spring. It provides reliable structure and year-round interest in mixed borders and hedges, and is one of the few shrubs that flowers well in part shade.
Varieties
- Viburnum tinus 'Lucidum' — Glossy, dark green leaves and a more compact habit, ideal for smaller gardens.
- Viburnum tinus 'Eve Price' — A popular cultivar with pink buds opening to white flowers, very free-flowering.
- Viburnum tinus 'Gwenllian' — Deep pink buds and a slightly more upright form, excellent for hedging.
Soil Preparation
Laurustinus prefers slightly acidic to neutral soil (pH 6.0–7.0) that is rich in organic matter and well-drained. Before planting, incorporate compost or well-rotted manure into the soil to improve fertility and structure. If soil is heavy clay, add gypsum and raise the bed to improve drainage.
Growing Guide
Plant laurustinus in well-drained soil enriched with organic matter, in a position that receives morning sun or dappled light. Space plants 1.5–2 m apart for hedges or 2.5–3 m for specimen shrubs. Dig a hole twice the width of the root ball, backfill with native soil mixed with compost, and water in well. Apply a 5–7 cm layer of mulch around the base, keeping it clear of the stem. Water deeply once a week for the first two growing seasons to establish a strong root system.
Care
Feed in early spring with a balanced slow-release fertiliser (e.g., 10-10-10) at the rate recommended for the plant's size. Prune lightly after flowering to shape and remove spent blooms, cutting back to a healthy bud. Mulch annually with 5–7 cm of organic mulch to retain moisture and suppress weeds.
Companion Planting
Pair laurustinus with other shade-tolerant evergreens such as camellia, rhododendron, and daphne for a layered winter border. Avoid planting near shallow-rooted trees like eucalypts that compete heavily for moisture. It also works well with spring bulbs like daffodils and bluebells planted at its base.
Common Pests & Risks
Aphids can cause distorted new growth; control with a strong water spray or horticultural oil in early spring. Scale insects appear as brown bumps on stems and leaves; treat with white oil in winter. Thrips may cause silvery mottling on leaves; use a systemic insecticide if damage is severe. Maintain good air circulation to reduce fungal issues like powdery mildew.
Troubleshooting
Yellow leaves: often caused by poor drainage or overwatering; improve soil drainage and reduce watering frequency. Brown leaf edges: usually from dry conditions or wind exposure; increase watering and provide a sheltered position. Sparse flowering: may be due to too much shade; move to a brighter spot or prune back overhanging branches. Leaf drop: can indicate root rot from waterlogged soil; check drainage and avoid planting in low spots. Powdery mildew: white coating on leaves in humid conditions; improve air circulation and apply a fungicide if needed.
