Establishment
First 4-6 weeks after plantingYoung plant focuses on root development with limited above-ground growth
Water regularly to keep soil consistently moist but not waterlogged. Provide afternoon shade in hot climates. Stake if necessary in windy locations.
Vegetative Growth
Spring through early summer (approximately 8-10 weeks)Plant develops dense foliage with small, elongated leaves; new stems emerge from base and branch tips
Prune lightly in early spring to shape and encourage bushiness. Remove dead or weak wood. Fertilize monthly with balanced fertilizer during growing season.
Flowering
June through September (3-4 months)Produces clusters of bright golden-yellow, five-petaled flowers at stem tips; blooms are 1-1.5 inches across
Deadhead spent flowers to encourage continuous blooming. Keep soil moderately moist. Avoid heavy pruning during flowering season.
Berry Development
Late summer through early winter (August-November)Flowers transition to ornamental berries that ripen from green to red, then deepen to burgundy or dark red
Reduce watering slightly to encourage berry development. Minimize pruning to preserve berry displays. Berries attract birds and wildlife.
Winter Dormancy
December through FebruaryFoliage may discolor in cold zones; berries persist on branches providing winter interest; growth slows significantly
No pruning needed. Reduce watering. In zone 5, apply 2-3 inches of mulch around base for protection. Protect from harsh winds.
