Seed/Germination
7-14 daysTiny seeds germinate in warm soil; first true leaves emerge within 7-10 days
Keep soil warm (70-75°F) and consistently moist but not soggy. Provide good light once sprouted. Thin seedlings to prevent crowding.
Seedling to Transplant
3-4 weeksSeedlings develop 2-4 true leaves and grow small but sturdy; ready for larger containers
Provide bright light (grow lights 2-3 inches above seedlings). Fertilize weakly with balanced liquid fertilizer every 1-2 weeks. Harden off before transplanting outdoors.
Vegetative Growth
2-3 weeks after transplantingPlant establishes compact, mounding form with increasing leaf development; 6-10 inches tall
Pinch terminal buds when 4-6 inches tall to encourage bushier growth (optional but recommended). Water consistently. Fertilize every 2-3 weeks with balanced or slightly lower-nitrogen fertilizer.
Flowering
8-12 weeks (from first flower until frost)Abundant pure white double flowers bloom prolifically on compact plants; continuous bloom through season
Deadhead spent flowers to encourage more blooms (optional; this variety is self-cleaning). Water at soil level to reduce fungal issues. Reduce nitrogen fertilizer; use bloom-boosting formula if desired.
Late Season/Decline
Until frost (typically 4-8 weeks depending on region)Flowering continues until first frost; plants gradually slow production in fall cool temperatures
Allow some flowers to fade for seed collection if desired. Continue deadheading for continuous blooms. Plant remains vigorous until hard frost.
