Establishment
4-6 weeksNew transplants focus on root development with minimal above-ground growth
Water regularly to keep soil moist. Protect from extreme temperatures and wind. Mulch to conserve moisture and regulate soil temperature.
Vegetative Growth
Spring through early summerShrub develops leafy stems and establishes a rounded, bushy form
Prune lightly to shape and encourage branching. Remove any dead wood. Apply balanced fertilizer in spring. Maintain consistent moisture.
Flowering
June to JulySmall, delicate yellow flowers appear in terminal clusters
Continue regular watering. Do not deadhead flowers as they develop into ornamental berries. Monitor for pests and diseases.
Berry Development & Maturation
August through NovemberFlowers transition to berries that turn from green to yellow to coral-red
Avoid heavy pruning during this phase. Maintain moderate watering. Berries reach peak color in fall. No fertilizer needed; excess nitrogen reduces berry production.
Winter Display
December through FebruaryBerries persist on branches through winter, providing ornamental interest even after leaf drop in colder zones
Minimal care needed. Berries may be harvested for arrangements. Prune back in late winter or early spring before new growth begins.
