Growth Stages

1

Establishment (0-6 months)

3-6 months

Young plant focusing on root development with limited new leaf growth

Water regularly to keep soil moist; mulch around base (not touching stem); protect from wind and full sun; avoid fertilizing until established

2

Vegetative Growth (6 months - 2 years)

6-24 months

Plant develops dense foliage and branch structure; gradual height and width increase

Maintain consistent moisture; apply light pruning to shape; apply native-appropriate mulch; monitor for pest issues in high-humidity conditions

3

Canopy Development (2-3 years)

12-18 months

Shrub reaches near-mature size with full canopy and characteristic form

Reduce watering frequency as roots deepen; prune only for shape; apply organic mulch; begin observing for flowering/fruiting indicators

4

Flowering/Fruiting (varies by species)

2-6 months depending on species

Species-dependent; many produce small flowers and colorful berries attractive to native birds

Maintain established watering schedule; avoid heavy pruning during flowering; allow fruits to mature for wildlife benefit

5

Mature (3+ years)

Ongoing

Plant at full landscape size with established branching and regular seasonal cycles

Minimal maintenance; prune selectively for shape; maintain mulch; reduce supplemental watering in established plantings
