Growth Stages

1

Establishment

4-6 weeks

Young transplants with minimal foliage spreading slowly outward

Water consistently 2-3 times weekly. Protect from hot afternoon sun in zones 8-9. Pinch back occasionally to encourage bushiness.

2

Vegetative Growth

6-10 weeks

Plant fills in as a dense, low mat with aromatic needle-like leaves

Reduce watering once established. Avoid high-nitrogen fertilizers. Deadhead or shear lightly after initial flowering to maintain shape.

3

Flowering

6-8 weeks (early to mid-summer)

Abundant small magenta-pink flowers cover the foliage on short spikes

Deadhead spent flowers to encourage continued blooming. Do not fertilize; nutrients encourage leaf growth over flowers.

4

Post-Bloom & Hardening

Late summer through fall

Flowers fade, foliage becomes denser and more compact; plant prepares for dormancy

Light shearing acceptable. Reduce watering slightly. No pruning needed for winter in most zones; foliage is evergreen.

5

Winter Dormancy

3-4 months

Evergreen foliage persists; minimal growth

No water or fertilizer needed. In zones 4-5, mulch lightly if snow cover is unreliable. Ensure drainage is excellent to prevent ice damage.
