Seedling
2-3 weeksTiny seedlings emerge with cotyledons, developing first true leaves within 1-2 weeks.
Keep soil consistently moist but not waterlogged. Provide bright light to prevent leggy growth. Thin seedlings if overcrowded.
Vegetative Growth
3-4 weeksPlant develops bushy foliage with multiple stems and feathery compound leaves, growing 12-36 inches tall depending on variety.
Pinch back growing tips when plants are 6 inches tall to encourage bushier growth and more flowers. Water moderately; allow surface soil to dry between waterings.
Budding
1-2 weeksFlower buds begin to form at branch tips, visible as small green protrusions within the foliage.
Maintain consistent watering and provide full sunlight. Apply balanced fertilizer every 2-3 weeks to support blooming. Remove any yellowing leaves.
Flowering
8-12 weeks or until frostWhite blooms fully open, displaying full, rounded flower heads with petals in shades of ivory to cream. Flowers continuously from midsummer through fall frost.
Deadhead spent flowers regularly to encourage continuous blooming. Water at soil level to keep foliage dry and prevent fungal disease. Stake tall varieties if needed.
Late Season & Seed Production
Until frostFlowering slows as temperatures cool and daylight decreases. If flowers are not deadheaded, seed pods develop for self-seeding next year.
Allow some flowers to remain on plants if you want self-seeding. Collect seed pods when brown and papery for seed saving. Plants typically decline after first hard frost.

Harvest Tips
Deadhead spent flowers regularly by pinching or cutting just below the flower head to encourage continuous blooming throughout the season. For cut flowers, harvest in the morning when stems are hydrated, cutting at a 45-degree angle. For seed saving, allow flowers to fade and remain on the plant; harvest seed pods when they turn brown and papery, then dry indoors before extracting seeds.
