Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with needle-like cotyledons emerge; very delicate with minimal foliage

Keep soil consistently moist but not waterlogged; provide bright light; thin seedlings to proper spacing once they have true leaves

2

Vegetative Growth

4-6 weeks

Plant develops dense mats of fine, needle-like foliage; spreads horizontally forming low cushions

Water moderately; avoid overhead watering to prevent fungal issues; thin crowded growth to improve air circulation

3

Pre-flowering

2-3 weeks

Foliage mats thicken and compact; flower buds begin forming at branch tips

Reduce nitrogen fertilizer; ensure excellent drainage; light shearing can promote bushier growth and more blooms

4

Flowering

4-6 weeks (typically April-May in cooler zones)

Abundant coral-pink flowers with red or darker eye centers cover the plant, completely obscuring foliage in full bloom

Deadhead spent flowers to encourage continued blooming; water during dry spells; avoid fertilizing, which promotes foliage over flowers

5

Post-bloom

4-6 months until dormancy or next bloom cycle

Flowers fade and set seed; foliage remains attractive green throughout summer and into winter

Deadhead to prevent excessive self-seeding; very light shearing after bloom encourages compact growth; reduce water as plant enters dormancy
