Seedling
2-3 weeksTiny seedlings emerge with two cotyledons, developing fine needle-like true leaves within 1-2 weeks.
Provide bright light, maintain consistent moisture (not soggy), and thin seedlings to proper spacing. Keep at 65-70°F for optimal germination.
Vegetative Growth
3-4 weeksPlant develops dense, bushy foliage with narrow, lance-shaped leaves. Stems become more robust and the plant spreads outward.
Pinch back growing tips when plants are 3-4 inches tall to encourage bushiness. Maintain consistent watering and provide full sun exposure.
Budding
2-3 weeksFlower buds begin forming at branch tips, appearing as tight, clustered structures.
Ensure adequate light and warmth (65-75°F). Continue regular watering and consider a balanced or slightly phosphorus-rich fertilizer to support flower development.
Flowering
8-12 weeks (extends with deadheading)Vibrant hot pink flowers open fully, displaying frilly or ruffled petals with slight fragrance. Plant may bloom in clusters.
Deadhead spent flowers regularly to encourage continuous blooming. Water consistently, and apply balanced fertilizer every 2-3 weeks to maintain vigor.
Extended Bloom to Senescence
Ongoing until frost or heat stressWith proper deadheading, flowers continue proliferating. Eventually, plant may decline in late summer heat or when first frost arrives.
Continue deadheading and watering. In extremely hot climates, afternoon shade can extend blooming. Discontinue heavy fertilizing in late season.
