Growth Stages

1

Establishment

First 6-12 months

Young plants with tender shoots and emerging bright green foliage; minimal branching structure

Water regularly to establish root system; provide shelter from harsh winds; avoid transplanting or heavy pruning in first season; apply mulch around base

2

Vegetative Growth

Year 2-3

Vigorous shoot development with dense foliage filling in; plant develops rounded, bushy form; bright glossy green leaves mature

Light pruning to encourage branching and shape; maintain consistent moisture; fertilize with balanced, slow-release fertilizer in spring; remove dead or diseased branches

3

Flowering

Spring, 2-4 weeks

Inconspicuous small yellowish-green flowers appear in spring among the foliage; flowers are not ornamentally significant

No special care needed; flowers attract pollinators; avoid heavy pruning during flowering to preserve flowers

4

Fruiting

Summer through autumn

Small purple-black berries develop after flowering if both male and female plants are present; berries ripen in summer-autumn

Allow berries to mature for ornamental effect and wildlife food; no intervention required

5

Mature

Year 4+ (indefinitely with proper care)

Full-sized shrub (8-12 feet tall and wide) with dense, compact growth habit and stable form; continuous bright green foliage

Maintain shape with annual pruning in late winter or early spring; reduce watering once fully established; monitor for pests occasionally; little fertilizer needed

Companion Planting

Plan your garden →

Plant with:

Coprosma (mirror bush) Phormium (New Zealand flax) Olearia (daisy bush) Hedera (ivy) Leptospermum (tea tree) Pittosporum Escallonia Hebe

Avoid planting near:

Plants requiring dry, well-drained conditions if soil is consistently wet Acid-loving plants in alkaline soils (broadleaf is tolerant but not ideal for their companions) Shallow-rooted plants that compete for moisture

Common Pests

  • Spray with horticultural oil in late winter; prune out heavily infested branches; encourage natural predators like ladybugs

  • Increase humidity with regular misting; spray with water to dislodge; use miticide if infestation is severe

  • Yellow sticky traps; spray with insecticidal soap; prune affected foliage

  • Usually not damaging; spray with neem oil if populations are high

Uses

Screening and Hedging

Harvest Tips

Not typically harvested for commercial use. For ornamental purposes, foliage can be cut for floral arrangements year-round. Prune in late winter or early spring before new growth; can be cut back hard if rejuvenation is needed. Maintain shape by removing straggly growth and shaping sides to encourage compact form.
