Establishment
First yearYoung shrub developing root system and initial branching structure
Water regularly during first growing season to establish deep roots. Mulch around base to retain moisture and suppress weeds. Avoid transplanting once established.
Vegetative Growth
Year 2-3Active shoot elongation with characteristic narrow, willow-like foliage developing along arching branches
Prune lightly after flowering to shape plant and maintain attractive form. Remove any dead or crossing branches. Apply balanced fertilizer in early spring.
Flowering
Late spring to early summer (4-6 weeks)Small white or pale pink flowers appear in flat clusters along branches, attracting bees and other pollinators
Ensure adequate sunlight for abundant flowering. Do not over-fertilize with nitrogen, which reduces bloom. Avoid heavy pruning during this stage.
Fruiting
Late summer through winter (4-6 months)Flowers give way to small bright red berries (sometimes orange-red) that persist through fall and into winter, providing ornamental interest
Do not remove berries; they attract birds and wildlife and persist for months. Ensure adequate sunlight and moderate fertility for best berry color.
Dormancy
Winter (variable by zone)In colder zones, plant becomes deciduous or semi-evergreen; foliage may develop reddish tones before dropping
Minimal care needed. Prune only to remove dead wood. The persistent berries remain ornamental throughout dormancy.
