Growth Stages

1

Establishment

3-6 months

Young plant focuses on root development with slow above-ground growth; foliage is bright blue-green and tender.

Water regularly (weekly in dry periods), provide shelter from harsh winds, mulch lightly to retain moisture while maintaining good air circulation around the base.

2

Vegetative Growth

1-2 years

Plant develops dense, spreading branching structure with increasing feathery foliage coverage; slower growth compared to non-compact varieties.

Maintain consistent watering schedule, apply light pruning to shape if desired, avoid over-fertilizing which promotes weak growth.

3

Mature Shrub

Ongoing

Plant reaches full compact form (typically 2-3 feet tall and 3-4 feet wide), develops deeper blue-green or grey-green coloration, shows full spreading habit.

Reduce watering frequency, prune only to maintain shape or remove dead wood, provide excellent drainage year-round.

4

Fruiting/Coning

Summer through winter

Small, waxy, blue-grey berry-like cones develop along branches, providing ornamental interest and food source for wildlife.

No special care needed; cones develop naturally and persist through winter; prune selectively around cones to avoid excessive removal.
