Growth Stages

1

Seedling

2-3 weeks

Tiny emerald leaves emerging from soil; delicate 1-2 inch tall plants with narrow foliage

Maintain consistent moisture without waterlogging. Provide bright light. Keep temperatures cool (65-70°F). Thin seedlings to prevent damping-off disease.

2

Vegetative Growth

4-6 weeks

Bushy growth with multiple shoots; gray-green linear leaves forming dense mounds, 6-12 inches tall

Pinch back growing tips at 6 inches to encourage branching. Provide full sun and excellent drainage. Water moderately and fertilize every 3-4 weeks with balanced fertilizer.

3

Budding

3-4 weeks

Terminal buds forming at stem tips; buds developing in clusters, enclosed in sepals

Support tall stems with stakes or cages if needed. Continue regular fertilization with slightly higher phosphorus to promote flowering. Remove any diseased foliage.

4

Flowering

4-8 weeks per flush

Large, fully double white blooms with ruffled petals opening sequentially; flowers 2-3 inches diameter on strong stems

Deadhead spent flowers regularly to extend blooming. Maintain consistent watering. Stake tall varieties. Cut flowers in early morning when stems are fully hydrated.

5

Mature/Dormancy

Ongoing through seasons

Plant slows growth and blooming in extreme heat or cold; foliage persists, may decline in harsh conditions

Reduce watering in winter. Remove dead foliage. In hot climates, provide afternoon shade. In cold climates, mulch for winter protection. Cut back by half in fall.
