Establishment
Year 1Young shrub with limited branching; foliage emerging in spring
Water deeply and regularly; mulch around base; avoid fertilizing first year; protect from harsh winds if in exposed location
Vegetative Growth
Years 2-3Foliage fills in, branch structure develops; dense mounding form takes shape
Light pruning to shape; maintain consistent moisture; apply balanced fertilizer in early spring if desired; mulch to retain moisture
Flowering
3-4 weeks in late springWhite lacecap flower clusters appear on branch tips in late spring (May-June)
Do not deadhead if berry production is desired; flowers are short-lived (2-3 weeks); avoid heavy pruning during flowering
Fruiting
Summer through winter (June-February)Flowers fade and berries develop, turning from green to bright red by late summer
No special care needed; berry production is heavy if flowering was successful; birds will begin feeding in fall and winter
Dormancy
Late fall through early spring (October-April)Foliage turns burgundy-red to maroon in fall; leaves drop; berries persist on bare branches through winter
Prune in late winter or early spring while dormant to shape plant; remove dead or crossing branches; no watering needed if adequate rainfall occurs

Harvest Tips
Not harvested for food. Prune for arrangement and decoration: cut flowering branches in late spring for indoor display, or cut berry-laden branches in fall/winter for seasonal arrangements. Prune immediately after flowering (June) to shape the plant and encourage denser growth next season. Remove deadwood and crossing branches anytime. Avoid heavy pruning in late summer/fall as this may reduce next year's flower and berry production.
Fun Facts
- 🌱 Compact Viburnum is a dwarf cultivar of the European Cranberry Bush (Viburnum opulus), bred specifically to achieve a more manageable size than the 10-15 foot species parent.
- 🌱 The bright red berries can persist on branches well into winter and even spring, providing critical food for migratory birds when other food sources are scarce.
- 🌱 Viburnum flowers typically require cross-pollination from another compatible viburnum variety for best berry set, though some berry production can occur with self-pollination.
