Seedling
2-3 weeksSmall plants with cotyledons (seed leaves) followed by true leaves. Seedlings are tender and require warmth.
Provide warmth (70-75°F), consistent moisture, and bright light. Thin seedlings to prevent damping off. Start indoors 6-8 weeks before last frost or direct sow after frost danger passes.
Vegetative Growth
4-6 weeksRapidly growing plants developing sturdy stems and increasingly feathery foliage. Plants are branching and establishing a full canopy.
Pinch back growing tips when plants are 6-8 inches tall to encourage bushier growth and more flower production. Water regularly and ensure excellent drainage. Apply balanced fertilizer every 2-3 weeks.
Bud Formation
2-3 weeksTerminal buds begin to form at branch tips. Plants are full and compact, with visible flower bud clusters.
Continue regular watering and feeding. Reduce nitrogen fertilizer to encourage flowering over foliage. Remove any diseased or weak lower foliage.
Flowering
8-12 weeks (until frost in cooler zones)Large, fully double blooms open in succession, creating dramatic displays. Plants may reach 2-4 feet tall depending on variety and growing conditions.
Deadhead spent flowers regularly to extend blooming season and encourage continuous flower production. Maintain steady moisture and feed every 2-3 weeks with flower fertilizer. Watch for spider mites in hot, dry conditions.
Seed Production (if allowed)
3-4 weeksIf flowers are not deadheaded, spent blooms develop large seed pods containing numerous viable seeds.
Allow late-season flowers to mature on the plant if saving seeds. Collect seed heads when fully dry and brown. Store seeds in cool, dry conditions for next season.
