Growing Japanese Andromeda (Pieris) for Early Spring Blooms

Pronunciation: pie-ee'riss

These broad-leaved evergreen shrubs display flower buds all winter, opening in early spring as long white tassels. Glossy, narrowly oval leaves form dense rosettes, often with red-tinged new growth. Andromedas prefer conditions similar to rhododendrons and azaleas. Excellent for rock gardens, foundations, and woodland edges.

Light

Full sun or partial shade; protect from afternoon sun.

Soil

Moist, well-drained soil; cannot tolerate wet soil.

Watering

Water thoroughly after planting, monitor for a week, then soak weekly in summer unless rainfall exceeds 1 inch/week. Established plants prefer evenly moist soil. When in doubt, don't water.

Fertilizer

Don't fertilize at planting or during first growing season. Established plants need light feeding—once in early spring with balanced granular fertilizer (5-10-10, 10-10-10, or organic). Follow label directions for water-soluble fertilizers.

Continuing Care

Shelter from wind and afternoon sun to reduce lace bug susceptibility. Canker, dieback, root rot, and nematodes may occur. Many varieties grow in Zone 4 in protected spots. In cold climates, keep well-watered (not soggy) until ground freezes to prevent winter desiccation. Prune to shape after flowering; remove dead/damaged branches in mid-spring.
