Seedling
7-14 daysTiny seedlings emerge with two cotyledons, developing first true leaves within 7-10 days.
Maintain consistent moisture and warmth (70-75°F). Provide bright light to prevent leggy growth. Thin seedlings to prevent damping-off.
Vegetative Growth
2-3 weeksYoung plants develop multiple stems and foliage in a compact, bushy form.
Pinch back growing tips at 6 inches tall to encourage branching and fuller shape. Keep soil evenly moist. Begin fertilizing every 2-3 weeks with balanced fertilizer.
Pre-Flowering
1-2 weeksFlowering buds begin to form at branch tips as plant reaches mature size.
Reduce nitrogen fertilizer; switch to higher-phosphorus formula to promote blooming. Maintain consistent watering.
Flowering
6-10 weeks (or until frost)Small white flowers bloom prolifically across the plant; continuous bloom cycle throughout warm season.
Deadhead spent flowers regularly to encourage more blooms. Water consistently; heat and dry conditions can stress plants. Fertilize every 2-3 weeks.
Late Season
Varies; season-dependentFlowering may slow in intense mid-summer heat; resumes with cooler fall temperatures.
Provide afternoon shade in very hot climates. Continue deadheading. Plant often produces seed if flowers are left unharvested.
