Growth Stages

1

Establishment

3-6 months

Young plant with developing root system and new shoots emerging

Water regularly to keep soil moist but not waterlogged. Protect from strong winds and extreme heat. Mulch around base to retain moisture.

2

Vegetative Growth

1-2 years

Vigorous shoot and foliage development; plant fills in and becomes denser

Prune lightly to encourage branching and compact shape. Remove any dead or damaged branches. Maintain consistent watering.

3

Maturation

Ongoing (2-3+ years)

Plant reaches desired size with full canopy; dense, glossy green foliage

Maintain shape with annual pruning in spring. Reduce watering frequency as plant is now drought-tolerant. Fertilize lightly in spring.

4

Flowering & Fruiting

Spring-fall

Small yellowish-green flowers appear in spring, followed by purple berries in late summer/fall

No special care needed. Flowers attract pollinators; berries attract birds. Prune after flowering if shaping is needed.
