Germination & Seedling
2-3 weeksTiny seedlings emerge with two cotyledons, developing true leaves within 1-2 weeks
Keep soil consistently moist but not waterlogged. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
3-4 weeksPlant develops bushy, compact foliage with multiple stems and leaves becoming more abundant
Pinch back growing tips at 4-6 inches tall to promote bushier growth. Water moderately and avoid overfeeding with nitrogen, which encourages foliage over flowers.
Budding & Early Flowering
2-3 weeksFlower buds form at the tips of stems; first blossoms appear in vibrant orange or yellow
Reduce nitrogen fertilizer and apply balanced or phosphorus-rich fertilizer to support blooming. Deadhead spent flowers to encourage continuous blooming.
Peak Flowering
6-12 weeks or until frostPlant is covered with open daisy-like flowers; stems may be harvested for bouquets
Deadhead regularly to extend flowering season. Water moderately at soil level. Monitor for pests and diseases. Cut flowers last 5-7 days in arrangements.
Decline & Seed Set
Until frostFlowers fade and seeds develop in the center of blooms if not deadheaded; plant slows as temperatures drop
Allow some flowers to remain on plant if saving seeds. Let seed heads dry on the plant before collecting. Can self-seed for next season in mild climates.
