Dormancy & Planting
2-4 weeksTubers are stored or freshly planted in warm soil with visible growth buds emerging within 2-3 weeks.

Vegetative Growth
4-6 weeksShoots emerge and develop into bushy plants with robust foliage. Multiple stems form as the plant establishes.
Pinch out growing tips when plant reaches 12 inches to encourage bushier growth and more flower buds. Stake or support tall varieties early. Water regularly.
Budding & Early Flowering
2-3 weeksFlower buds appear at stem tips. First blooms begin to open, showing characteristic coral-red coloring.
Apply balanced fertilizer every 2-3 weeks. Deadhead spent flowers to encourage continued blooming. Remove lower leaves to improve air circulation.
Peak Flowering
6-12 weeksPlant is covered with large double flowers in vibrant coral-red, blooming profusely on strong stems.
Continue deadheading regularly. Provide consistent water and nutrients. Stake if needed to support heavy flower heads. Cut flowers for arrangements regularly.
Decline & Dormancy
4-8 weeksBlooming slows as temperatures drop in fall. Foliage yellows and dies back as tuber enters dormancy.
Stop fertilizing. Reduce watering. After frost kills foliage, cut stems to 2-4 inches and dig tubers. Clean, dry, and store in cool place over winter.
