Growth Stages

1

Establishment

3-6 months

Young plant with initial leaf growth and root system development

Water regularly to establish deep roots. Provide shelter from harsh winds. Mulch around base to retain moisture.

2

Vegetative Growth

6-18 months

Plant develops bushy form with increasing foliage coverage

Prune lightly to encourage branching and dense growth. Remove any diseased or dead wood. Monitor for pests.

3

Flowering

2-3 months (typically spring)

Small white flowers appear along branches in clusters

Maintain consistent moisture during flowering. Do not heavily prune during this period. Light feeding with balanced fertilizer is beneficial.

4

Fruiting

3-4 months

Flowers develop into clusters of distinctive bright red berries

Ensure adequate water during fruit development. Protect from extreme heat if in hot climates. Fertilize sparingly to avoid excessive vegetative growth.

5

Maturity

Ongoing

Established shrub with regular annual flowering and fruiting cycles

Prune after fruiting to maintain shape and encourage next season's flowers. Thin out congested growth. Continue regular watering during dry periods.
