Establishment

4-6 weeks

Young plants with thin, needle-like foliage establishing root systems

Keep soil consistently moist but not waterlogged during first 4-6 weeks. Mulch lightly with gravel to suppress weeds. Avoid fertilizer.

2

Vegetative Growth

8-12 weeks

Mat expands with increasing needle-like foliage; no flowering yet or minimal flowers

Flowering

4

Post-Bloom

Flowers fade; foliage remains attractive and may green up in summer

Optional: shear plants back by one-third to one-half after flowering to maintain compactness and prevent legginess. Reduce watering significantly.

Dormancy

4-6 months

Foliage persists or becomes evergreen depending on climate; plant enters winter dormancy

No watering needed unless prolonged drought. Ensure good drainage to prevent winter rot. No fertilizer needed.
