Planting & Care Instructions
Sunlight: Radiance Abelia performs best in part shade, which enhances its variegated foliage color. It tolerates full sun but may show reduced color vibrancy in intense afternoon heat, particularly relevant for inland California climates like the Sacramento area.
Watering: Water regularly during the first growing season to help its root system to establish and aim for deep watering 2–3 times per week until. Once established, Radiance Abelia is moderately drought tolerant and typically requires watering once per week during hot summer months in California.
Soil: Plant in acidic, well-drained soil. Amend heavy clay soils with compost before planting to improve drainage. A soil pH of 5.5–6.5 is ideal.
