Seedling
2-3 weeksTiny seedlings with first true leaves appearing. Very delicate and slow-growing at this stage.
Maintain high humidity and consistent moisture. Provide bright indirect light. Use grow lights if needed. Keep soil temperature around 70-75°F.
Vegetative Growth
2-3 weeksPlant develops branching stems and dense foliage. Compact mounding shape becomes apparent. Multiple leaf nodes form along stems.
Begin fertilizing weekly with balanced liquid fertilizer (20-20-20). Pinch growing tips when 3-4 inches tall to encourage bushiness. Maintain shade and consistent moisture.
Budding & Early Flowering
1-2 weeksSmall flower buds form at leaf axils. First blooms appear in mixed colors. Plant becomes increasingly floriferous.
Continue weekly fertilization or switch to bloom-promoting formula (higher phosphorus). Deadhead spent flowers to encourage continuous blooming. Maintain consistent watering.
Peak Flowering
6-12 weeks (or until frost for annuals)Plant is covered with abundant flowers in multiple colors—red, pink, white, orange, and bi-colors. Compact, mounding form is fully developed.
Continue deadheading. Feed every 7-10 days. Monitor for spider mites and whiteflies. Ensure adequate air circulation to prevent fungal issues.
Decline or Overwintering
Variable; until frost or into dormancyFlowering slows as temperatures drop (if grown as annual) or plant enters dormancy. Foliage may deteriorate.
If overwintering indoors, reduce watering and move to cooler location (60-65°F). Cut back fertilization. Provide bright indirect light. Prune heavily in spring if keeping.
