Seedling
2-3 weeksTiny plants with 2-4 true leaves emerging; delicate appearance with fine foliage
Keep soil consistently moist but not soggy; provide bright light (12-14 hours daily); maintain 65-70°F for optimal germination
Vegetative
3-4 weeksBushy growth with densely packed green foliage; multiple shoots developing; plant becomes fuller
Pinch back tips when 3-4 inches tall to encourage branching; reduce watering slightly; apply balanced fertilizer every 2 weeks
Budding
1-2 weeksCompact buds forming at branch tips; foliage remains lush green; plant takes on dense, mounded shape
Maintain consistent watering; apply low-nitrogen fertilizer to encourage blooming; deadhead any early flowers to promote more buds
Flowering
6-12 weeks or longer with deadheadingAbundant, clustered flowers open; blooms display full colors and fragrance; plant becomes a solid mass of flowers
Deadhead spent flowers regularly to extend blooming; maintain consistent moisture; fertilize every 3-4 weeks with bloom-promoting formula
Decline
Variable; extends with proper careFlowering slows in intense heat or after many weeks of bloom; foliage may yellow slightly
Cut back plant by one-third if blooming slows in summer; increase watering; move containers to partial shade in extreme heat
