How to grow escallonia
Overview
Escallonia is an evergreen shrub grown for its dense foliage and reliable seasonal interest, often used as a hedge or screen. It provides structure and texture in the garden, linking bolder feature plants together.
Varieties
- Escallonia rubra 'Crimson Spire' — Compact, upright growth with deep crimson flowers; ideal for formal hedges in temperate zones.
- Escallonia 'Apple Blossom' — Pale pink flowers and dense foliage; popular for informal screens in coastal gardens.
- Escallonia 'Iveyi' — White-flowered variety with glossy leaves; excellent for a softer look in subtropical climates.
Soil Preparation
Escallonia prefers slightly acidic to neutral soil (pH 6.0–7.0) with good drainage. Amend heavy clay with gypsum or organic matter to improve drainage; add compost before planting.
Growing Guide
Plant in full sun with well-drained soil; space 60–90 cm apart for a dense hedge. Dig a hole twice the width of the root ball, backfill with compost, and water in well. Mulch around the base to retain moisture and suppress weeds. Avoid planting in heavy clay or waterlogged sites.
Care
Feed with a balanced slow-release fertiliser in early spring. Prune lightly after flowering to maintain shape and encourage dense growth; remove dead or damaged wood in late winter.
Companion Planting
Escallonia pairs well with lavender, rosemary, and other Mediterranean shrubs for a cohesive look. Avoid planting near shallow-rooted trees like eucalypts that compete for moisture.
Common Pests & Risks
Scale insects and leaf spot are common; treat scale with horticultural oil in winter. Leaf spot can be managed by improving air circulation and avoiding overhead watering.
Troubleshooting
Yellow leaves: often due to poor drainage or overwatering; improve soil and reduce watering. Brown leaf edges: caused by salt burn or dry winds; mulch and shelter from wind. Sparse growth: insufficient light; move to full sun. Leaf drop: scale infestation; treat with oil.
