Growth Stages

1

Seedling

2-3 weeks

Tiny linear leaves emerge; plant remains very low and compact

Keep soil moist but not waterlogged. Provide bright light and good air circulation to prevent damping-off. Thin seedlings to proper spacing early.

2

Vegetative Growth

4-6 weeks

Dense cushion of narrow, blue-green foliage develops; plant gradually fills out horizontally

Pinch growing tips once or twice to encourage bushier growth and more flower buds. Ensure excellent drainage and air circulation. Avoid nitrogen-rich fertilizers that promote foliage over flowers.

3

Bud Formation & First Blooms

2-3 weeks

Flower buds appear at stem tips; semi-double pink blooms with deeper centers begin opening

Deadhead spent flowers regularly to encourage continued blooming. Provide balanced or low-nitrogen fertilizer. Maintain consistent moisture without waterlogging.

4

Peak Flowering

6-12 weeks (spring through summer, may repeat in fall)

Plant is covered in semi-double fragrant pink flowers; peak ornamental display

Deadhead spent blooms daily or every 2-3 days to maximize flowering. Water at soil level only. Apply mulch around base to maintain even moisture and keep foliage dry.

5

Late Season & Winter Dormancy

Fall through spring

Blooming slows as temperatures cool; foliage remains evergreen and compact in most zones

Reduce watering significantly. Cut back lightly after frost or in early spring; do not heavily prune. Ensure excellent winter drainage. Divide every 2-3 years to maintain vigor.
