Vegetative Growth
3-4 weeksPlant develops bushy foliage with multiple stems and compound leaves. No flowers present yet.
Pinch back growing tips when 4-6 inches tall to encourage branching. Provide full sun and maintain moderate moisture. Fertilize lightly with balanced fertilizer every 2-3 weeks.
Bud Formation
2-3 weeksSmall rounded buds form at stem tips. Plant is full and compact with visible flower buds developing.
Continue pinching if desired for more flowers. Do not overwater. Reduce nitrogen fertilizer; apply phosphorus-rich fertilizer to support flowering.
Flowering
8-12 weeks (can extend with deadheading)Large, fully double orange blooms open. Plant becomes covered with flowers. Blooms continue through season if deadheaded.
Deadhead spent flowers regularly to encourage continuous blooming. Water when soil surface dries. Apply low-nitrogen fertilizer every 3-4 weeks or use slow-release granules.
Senescence

Harvest Tips
Deadhead (remove spent flowers) regularly by pinching off spent blooms just below the flower head to promote continuous flowering throughout the season. For seed collection, leave some flowers to mature and dry on the plant, then harvest seed pods when brown and dry. Cut flowers last 5-7 days in a vase with fresh water.
