Growth Stages

1

Establishment

4-6 weeks

Young transplants with fine needle-like foliage establishing root systems

Water regularly but allow soil to dry between waterings. Ensure excellent drainage. Avoid fertilizer; lean soil is ideal.

2

Vegetative Growth

6-10 weeks

Dense, cushion-like mounds of dark green needle foliage forming; no flowers yet

Maintain moderate watering during dry spells. Avoid excessive fertilizer which promotes weak growth and disease. Keep soil well-draining.

3

Flowering

6-8 weeks

Delicate white pompom flower heads (about ½ inch diameter) appearing on thin stems 4-6 inches above foliage

Remove spent flowers to encourage continued blooming. Water at base during extended drought. No deadheading required but improves appearance.

4

Prolific Bloom

4-6 weeks

Peak flowering with numerous white flower clusters creating an airy, cotton-like display

Continue deadheading for extended bloom. Provide consistent but light watering. Avoid overhead watering which damages delicate flowers.

5

Dormancy/Fall Transition

4-5 months

Flowers fade; foliage remains evergreen but may take on bronze or reddish tones in cold climates

No watering needed unless soil becomes dust-dry. Do not cut back in fall; allow evergreen foliage to overwinter. No fertilizer needed.
