Growth Stages

1

Establishment

6-12 months

Young plant with minimal growth; focus on root development below ground

Water regularly to keep soil evenly moist; apply 2-3 inches of mulch; avoid fertilizing first year; prune only to shape if needed

2

Vegetative Growth

1-3 years

Dense foliage development with glossy, dark green oval leaves; plant reaches 50-75% of mature size

Water moderately; light pruning to encourage bushiness; apply balanced fertilizer in spring; maintain mulch layer

3

Flowering

2-4 weeks, typically spring (March-May in southeastern US)

Small, fragrant white flowers appear in small clusters (umbels) throughout the canopy

Do not prune during flowering; ensure adequate water; light pruning after blooming; pollination by insects is important for fruit set

4

Fruiting & Berry Development

3-4 months, summer through fall

Small round berries develop, transitioning from red to dark red to black as they mature; birds begin feeding

Provide consistent moisture; do not prune; allow berries to mature for full color and wildlife benefit; cross-pollination with another viburnum improves berry set

5

Mature Plant

Ongoing

Fully established shrub 6-12 feet tall and wide with dense evergreen foliage; reliable annual flowering and fruiting

Prune lightly after flowering to maintain shape; minimal fertilizer needed; occasional deep watering during drought; monitor for pests; enjoy wildlife activity
