Seedling
2-3 weeksTiny seedlings emerge with cotyledons (seed leaves); develop first true leaves within 1-2 weeks.
Keep soil moist but not soggy. Provide bright light and good air circulation to prevent damping off. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
2-3 weeksPlant develops multiple branching stems and lush foliage; gradually increases in height and bushiness.
Water moderately; avoid overwatering. Pinch off the top 1-2 inches when 4-6 inches tall to encourage branching and fuller growth. No fertilizer needed unless soil is extremely poor.
Flowering
4-8 weeks (longer in cool climates)Distinctive ruffled, rose-pink double blooms appear in clusters along stems; continuous flowering if deadheaded.
Deadhead spent flowers regularly to extend bloom time. Water during dry spells but avoid wet foliage. Support tall varieties with stakes if needed. Cool temperatures extend flowering.
Peak Bloom & Maintenance
3-4 weeksPlant is at maximum flower production with densely packed blooms; maintains ornamental value.
Continue deadheading for continuous blooms. Reduce watering if temperatures rise significantly. In hot climates, provide afternoon shade to prolong flowering.
Seed Set & Decline
2-3 weeksIf not deadheaded, plant produces seed pods and flowering slows; plant eventually senesces.
Allow some flowers to remain for self-seeding or seed collection. Stop deadheading toward end of season if you want seed for next year. Plant naturally ends as weather warms.
