Seedling
2-3 weeksTiny seedlings with two cotyledons (seed leaves) appear within 7-14 days. First true leaves are narrow and delicate.
Maintain warm soil (70-75°F for optimal germination). Keep soil moist but not soggy. Provide bright light to prevent leggy growth. Thin seedlings to prevent overcrowding.
Vegetative
3-4 weeksPlant develops multiple sets of elongated, lance-shaped leaves. Stems thicken and branch out. Plant reaches 6-24 inches tall depending on variety.
Maintain consistent moisture and full sun exposure. Pinch off terminal bud when seedlings have 4-6 true leaves to encourage bushier growth. Fertilize biweekly with balanced fertilizer.
Flowering Initiation
1-2 weeksFlower buds begin forming at stem tips. The characteristic crested or velvety texture becomes visible as tiny flowers cluster tightly together.
Continue regular watering and feeding. Reduce nitrogen fertilizer slightly to encourage flowering over foliage. Ensure at least 6 hours of direct sun daily.
Blooming
6-12 weeks or until frostFull, velvety crested flower heads open with rich colors. Flowers remain attractive for extended period (often until frost). Plant becomes focal point in garden.
Deadhead spent flowers to encourage continued blooming. Water during dry spells. Support tall varieties with stakes if needed. Monitor for pests.
Decline
Until first frostFlowers fade and lose color; foliage may yellow as temperatures cool. Plant growth slows dramatically.
Plant will decline with frost and freezing temperatures. Allow some flowers to remain if saving seeds. Cut back and compost after frost kills plant.

Harvest Tips
For fresh arrangements, cut flowers in early morning when stems are fully hydrated. Cut just below the flower head with sharp scissors. Flowers last 1-2 weeks in a vase with fresh water. For dried arrangements, cut flowers when fully mature and hang upside down in a warm, dry location for 1-2 weeks. Allow some flowers to remain on plant to self-seed for next season if desired.
