Seedling
2-3 weeksSmall green cotyledons emerge with first true leaves appearing within 1-2 weeks. Plants are delicate and vulnerable.
Keep soil consistently moist but not waterlogged. Provide bright light and maintain 70-75°F. Thin seedlings to proper spacing once they develop true leaves.
Vegetative Growth
3-4 weeksPlants develop sturdy stems and increasingly larger leaves. Growth is rapid in warm conditions. Plants reach 6-12 inches tall depending on variety.
Pinch back the growing tips when plants are 6 inches tall to encourage bushier, more compact growth and more blooms. Water when top inch of soil is dry. Begin fertilizing every 2-3 weeks.
Budding
1-2 weeksTerminal flower buds begin forming at the ends of branches. Plant structure is fully established with dense foliage.
Continue regular watering and fertilizing. Deadhead any early flowers to redirect energy into more bud production. Monitor for pests and diseases.
Flowering
8-12 weeks (until frost)Large, colorful pompom-like flowers in mixed bright colors bloom prolifically. Flowers are 2-3 inches in diameter with full, layered petals.
Deadhead spent flowers regularly to encourage continuous blooming. Maintain consistent water supply. Feed every 2 weeks with balanced or bloom-promoting fertilizer. Cut flowers for arrangements to promote more flowering.
Seed Production
2-3 weeks after flowering stopsIf flowers are not deadheaded, they develop seed heads as petals fade and dry. Seeds mature within the flower head.
Allow flowers to remain on the plant if you wish to collect seeds. Once fully dry and brown, remove seed heads and store in cool, dry location. Collect seeds before frost.

Harvest Tips
Cut flowers in early morning when stems are fully hydrated for longest vase life (7-10 days). Cut flowers just as petals are opening, above a leaf node to encourage branching. Pinching back tall stems also encourages more branching and fuller plants. Deadhead spent blooms regularly to maintain continuous flowering throughout the season. For seed collection, allow flowers to dry completely on the plant, then remove seed heads and dry indoors before storing.
Fun Facts
