Establishment
First 6-12 monthsYoung transplant with minimal new growth
Water regularly, mulch base with 2-3 inches of organic mulch, protect from extreme heat first season
Vegetative Growth
Months 6-24Vigorous branch and foliage development, dense compact form emerging
Light pruning to shape, maintain consistent moisture, fertilize spring and early summer with balanced fertilizer
Flowering
November through March (peak winter bloomer)Pink buds opening to white-tinged pink flower clusters (panicles) appearing along branches
Do not heavily prune during flowering; deadhead spent flowers if desired for tidiness; allow some flowers to set seed for berries
Fruiting
December through FebruarySmall ornamental blue-black berries develop where flowers were pollinated
Berries persist through winter; do not over-deadhead to allow berry formation; provide cross-pollination if possible with other viburnums
Mature Specimen
Year 3 onwards indefinitelyDense, rounded shrub 6-8 feet tall, continuously cycling through flowering and fruiting
Annual pruning after flowering to maintain shape and size; remove dead/diseased wood; occasional rejuvenation pruning every 3-4 years
