Seedling
2-3 weeksTiny sprouted plants with small oval cotyledons and first true leaves appearing
Maintain warm soil (70-75°F), high humidity, and bright indirect light. Keep soil consistently moist. Thin seedlings to prevent crowding.
Vegetative Growth
4-6 weeksPlant develops bushy foliage with increasingly numerous green leaves on branching stems
Pinch back growing tips to encourage bushiness and branching. Maintain warm temperatures (65-75°F) and consistent watering. Fertilize every 2 weeks with balanced fertilizer.
Flowering Initiation
1-2 weeksFirst flower buds appear at leaf axils; tiny red buds form along stems
Ensure 6-8 hours of direct sun daily to promote flowering. Switch to higher-phosphorus fertilizer to support blooms. Maintain consistent moisture and humidity.
Full Flowering
8-12 weeks or longer in warm climatesMultiple bright red tubular flowers with white and dark purple-black tips bloom continuously along stems
Deadhead spent flowers to encourage continuous blooming. Keep watering consistent. Continue weekly fertilizing. Monitor for pests attracted to flowers.
Dormancy/Winter
3-5 months depending on climateIn frost-prone areas, plant growth slows or stops; foliage may thin and flowering decreases
Reduce watering frequency. Bring potted plants indoors before first frost. Cut back by one-third in late winter to rejuvenate. Minimal fertilizing needed.
