1. Site Selection

Light

• Tolerates some morning sun but avoid harsh afternoon heat
• Great for north‑facing beds or under hedges

Soil

2. Planting Vinca minor ‘Illumination’

Best Planting Time

3. Watering

• Keep soil consistently moist during establishment
• After settling, water lightly — Vinca is drought‑tolerant
• Avoid waterlogged soils (may cause fungal issues)

4. Fertilisation
