Establishment
3-6 monthsYoung shrub with sparse branching and small stature (first year after planting)
Water regularly to establish deep roots. Mulch around base to retain moisture. Avoid heavy pruning in the first year.
Vegetative Growth
Late spring through fallShrub expands in size and develops a fuller branching structure with light green foliage
Continue regular watering during dry spells. Apply balanced fertilizer in early spring. Begin light shaping pruning immediately after flowering if needed.
Pre-flowering
December-February (depending on zone)Flower buds develop along branches in late winter; buds appear as small, swollen growths on stems
Do not prune during this stage as you'll remove flower buds. Avoid late frosts which can damage developing buds. No fertilizing needed.
Flowering
2-4 weeks (typically March-April depending on zone)Abundant four-petaled yellow flowers cover the branches before or as leaves emerge; blooms can be pale to bright golden yellow
Prune immediately after flowering ends to shape the shrub and encourage next year's buds. Deadheading is not necessary but light pruning directs growth.
Foliage & Maturity
May-NovemberDark green leaves fully develop and shrub reaches its mature height (3-4 feet); little ornamental interest until next spring
Water during dry periods. Can fertilize lightly in late spring if desired. Minimal pruning except to maintain shape; prune only in summer after flowering period ends.
