Seedling
4-6 weeksTiny seedlings with first true leaves appearing; delicate and light green
Keep soil moist but not waterlogged. Provide bright, indirect light. Maintain temperatures above 70°F for best germination (60-70 days).
Vegetative Growth
4-6 weeksPlant develops multiple stems and bushy foliage; dark green leaves are glossy and oval-shaped
Pinch back growing tips to encourage bushier growth. Fertilize every 2-3 weeks with balanced fertilizer. Keep consistently moist but well-draining.
Budding
2-3 weeksFlower buds form at branch tips; plant continues to fill out
Maintain regular watering and fertilizing schedule. Ensure full sun exposure for abundant buds. Watch for pests.
Flowering
Throughout warm season (8-12 weeks or more)Five-petaled pink flowers with contrasting centers bloom continuously; flowers measure 1-1.5 inches across
Deadhead spent flowers regularly to encourage continued blooming. Maintain watering schedule and apply diluted fertilizer every 3-4 weeks. Vinca tolerates heat and drought at this stage.
Seed Production
3-4 weeksIf not deadheaded, flowers fade and elongated seed pods develop; plant energy shifts to seeds
Allow some flowers to remain if collecting seeds. Seeds mature in 3-4 weeks after flowering. Harvest seed pods when they turn brown and dry.
