Growth Stages

1

Establishment

First 6-12 months

Young plant focuses on root development with slow above-ground growth; small leaves appear

Keep consistently moist but not waterlogged; provide shelter from strong winds; stake if needed; apply mulch around base

2

Vegetative Growth

Year 1-2

Plant develops dense branching and accumulates foliage; compact form becomes apparent

Light pruning to encourage bushiness; fertilize monthly during growing season with balanced fertilizer; maintain consistent moisture

3

Flowering

May-July (4-8 weeks)

Small, fragrant white flowers with prominent stamens appear in late spring to early summer

Reduce nitrogen fertilizer to encourage flowering; deadhead spent flowers to promote continuous blooming; ensure adequate sunlight

4

Fruiting & Hardening

August-October (8-12 weeks)

Small, round berries develop from flowers, progressing from red to dark blue-black; foliage hardens

Reduce watering slightly; allow berries to mature fully before winter; apply light pruning only; reduce fertilizer

5

Dormancy

November-March (4-5 months)

Growth slows dramatically; plant enters semi-dormant state in cooler zones while remaining evergreen

Minimal watering; no fertilizer; protect from hard freezes with frost cloth in zone 8b; prune only to remove dead wood
