Growth Stages

1

Establishment

First 1-2 years

Young plant with developing root system and initial branching; compact form begins to establish

Keep soil consistently moist but not waterlogged. Shelter from harsh winds. Light mulch to retain moisture. Avoid fertilizer in first year.

2

Vegetative Growth

3-10 years

Gradual increase in density and height; fine-textured foliage becomes more prominent; pyramidal form develops

Maintain consistent watering during growing season. Prune only to maintain shape or remove dead branches. Apply balanced slow-release fertilizer in spring.

3

Mature Landscape Form

10+ years

Reaches typical ornamental size (2-5 feet tall depending on cultivar selection); dense, compact, well-defined shape

Water during drought periods. Mulch around base to conserve moisture and regulate soil temperature. Monitor for pests. Minimal pruning needed.

4

Seasonal Dormancy

October-March (varies by region)

Winter rest period; foliage may develop bronze or purplish tones in cold climates; growth ceases

Reduce watering frequency. Protect from harsh winds and heavy snow damage with stakes or guards if necessary. No fertilizing.
