Growth Stages

1

Germination

14-21 days

Tiny seedlings emerge with cotyledons; very slow and delicate growth

Maintain 70-75°F soil temperature; provide bright indirect light; keep soil moist with fine mist; ensure excellent air circulation to prevent damping-off

2

Seedling

4-6 weeks

Development of first true leaves; slow growth continues; plants remain small and fragile

Grow under bright lights 14-16 hours daily; maintain humidity around 60-70%; begin very light fertilization at half strength

3

Vegetative Growth

6-8 weeks

Plant develops branching stems and elongates; foliage becomes more robust

Harden off gradually when temperatures reach 60°F; space properly to avoid crowding; pinch growing tips once to encourage bushier growth; continue regular feeding

4

Bud Formation

3-4 weeks

Visible buds appear at stem tips; plant achieves near-full size before flowering

Continue consistent moisture and feeding; provide support with stakes if needed; reduce nitrogen to encourage flowering over foliage

5

Flowering

6-12 weeks total flowering

Large, showy flowers open with ruffled, papery petals; blooms progress from lower to upper buds

Deadhead spent flowers to extend bloom season; maintain consistent watering; reduce fertilizer; enjoy 3-4 week blooming period per flower
