Growth Stages

1

Establishment

First 6-12 months

Young shrub with minimal branching and small leaves; initial root development

Water regularly to establish roots. Protect from extreme winds. Avoid heavy pruning in first year.

2

Vegetative Growth

1-2 years

Vigorous branching; dense foliage development with medium-green leaves

Provide consistent moisture. Light pruning to shape. Apply balanced fertilizer in spring.

3

Flowering

3-4 weeks in early spring

Delicate white catkins emerge on branches; soft, fuzzy flower clusters

Minimal intervention needed. Light pruning after flowering to maintain shape. Do not deadhead unless shaping.

4

Fruiting

4-6 weeks post-flowering

Flowers fade; small capsule-like fruits develop; foliage remains lush

Continue regular watering. Optional light pruning to remove spent flower stems.

5

Dormancy

October to March (depending on zone)

Leaves fade and drop in fall; bare branches reveal structure; plant prepares for winter rest

Reduce watering gradually. No fertilizer. Prune only to remove damaged wood. Mulch around base for winter protection in colder zones.
