Seed Germination
7-14 daysTiny seeds begin sprouting; seedlings emerge with fine, delicate cotyledons
Keep soil moist but not soggy. Provide light (do not cover seeds completely). Maintain temperature of 65-70°F. Thin seedlings to prevent damping off.
Seedling
3-4 weeksYoung plants develop their first true leaves; growth is slow initially but steady
Provide bright light (grow lights recommended). Keep soil evenly moist. Maintain humidity around 50-60%. Begin light fertilization at half strength.
Vegetative Growth
2-3 weeksPlants develop bushy foliage with increasingly dense branching; no flowers yet
Pinch growing tips to encourage branching and fuller shape. Harden off seedlings before transplanting outdoors. Continue moderate watering and weekly fertilization.
Flowering
6-10 weeks or until frostSmall daisy-like flowers appear in abundance; blooms are 0.5-0.75 inches across in blue, purple, pink, or white
Deadhead spent flowers regularly to encourage continuous blooming. Provide consistent moisture and weekly fertilization. Reduce nitrogen to promote more flowers over foliage.
Late Season
Until frost or natural declineFlowering continues but may slow slightly in heat; plants can be rejuvenated by pruning
Cut back by one-third if plants become leggy. Provide afternoon shade in very hot climates. Continue deadheading. Plants decline with first frost.

Harvest Tips

Cut flowers for bouquets in early morning when stems are most turgid. Harvest entire stems rather than individual flowers for longer-lasting cuts.
