Establishment (Year 1)
4-6 months after plantingYoung shrub focused on root development and establishing branch structure. Foliage is bright green and tender; plant is relatively small.
Water regularly (2-3 times weekly in first season), apply 2-3 inches of mulch, stake if windy, prune only to remove dead wood. Avoid heavy fertilization.
Vegetative Growth (Years 1-2)
12-18 monthsShrub develops dense, bushy form with fine, glossy, dark green evergreen foliage. No flowers or berries yet.
Continue regular watering and mulching. Light shaping prune in late winter/early spring to encourage branching. Reduce watering frequency once established (weekly unless drought).
Flowering (Spring, Years 2+)
3-4 weeks (May-June)Small, inconspicuous white or cream flowers appear in clusters in late spring (May-June). Flowers are fragrant but easily overlooked.
Ensure a compatible male pollinator (like 'Jersey Knight') is within 30-50 feet. Do not prune flowers off. Flowers typically self-compatible somewhat but need male pollen for best fruit set.
Fruit Development (Summer-Fall)
12-14 weeks (June through September-October)Small, glossy black berries develop from pollinated flowers, covering the foliage by late summer and persisting through winter.
Maintain consistent moisture during fruit development. Do not prune berries off—they persist and attract wildlife. Berries are more abundant with adequate sunlight and a pollinator nearby.
Dormancy/Winter Display (Fall-Winter)
6-8 months (November-March)Evergreen foliage remains glossy dark green while black berries persist on branches, creating striking winter ornamental effect.
Minimal care; water only during extended dry periods. Prune selectively in late winter if needed (before spring growth). Berries provide food for birds through winter.
