Seedling
2-3 weeksTiny seedlings with first true leaves appearing 7-10 days after germination. Plants are delicate and low-growing.
Maintain warmth (70-75°F), keep soil moist but not soggy, provide bright light. Avoid damping off by ensuring good air circulation.
Vegetative Growth
3-4 weeksYoung plants developing multiple leaves and branching structure. Rapid height increase with increasingly robust stems and foliage.
Pinch back growing tips at 4-6 inches to encourage bushy branching. Provide adequate spacing for air circulation. Begin fertilizing every 2 weeks.
Budding & Early Flowering
2-3 weeksFirst flower buds appear at branch tips. Plant reaches mature height and form with dense foliage.
Continue regular watering and feeding. Remove any diseased foliage. Support tall varieties with stakes if needed. Deadhead spent blooms to encourage more flowers.
Peak Flowering
4-8 weeksAbundant, vibrant blooms cover the plant. Colors are most intense and vivid. Multiple flowers at various stages simultaneously.
Deadhead regularly to maximize bloom production. Water consistently. Apply balanced or bloom-boosting fertilizer every 2-3 weeks. Monitor for pests.
Late Season & Senescence
Until frost or end of growing seasonBlooming may slow as temperatures drop in fall or as plants mature. Seeds develop on missed flowers.
Continue deadheading if wanting continuous blooms. Reduce fertilizer frequency. Allow some flowers to go to seed if collecting seed for next year.

Harvest Tips
Cut flowers in early morning when stems are fully hydrated for best vase life. Remove lower foliage before arranging. Cut just above a leaf node to encourage branching and more blooms. Cutting regularly actually promotes more flowering throughout the season. For seed saving, allow some late-season flowers to develop seed pods fully before collecting.
