Seed Germination
7-10 daysTiny seeds barely visible; require light exposure for germination
Keep soil consistently moist but not waterlogged. Germination occurs in 7-10 days at 70-75°F. Do not cover seeds with soil.
Seedling
3-4 weeksFirst true leaves emerge; plants are very small and delicate with thread-like foliage
Provide bright light (grow lights if indoors). Keep soil moist. Thin seedlings to proper spacing. Begin light fertilizing at half strength.
Vegetative Growth
2-3 weeksBushy, compact plants develop with finely divided, feathery foliage; no flowers yet
Pinch growing tips when plants reach 6 inches tall to encourage bushier growth. Water moderately. Reduce fertilizer; too much causes leafy growth without flowers.
Flowering & Blooming
8-12 weeks (until frost in zones 2-8)Abundant small, daisy-like flowers cover compact plants; colors include pink, red, orange, white, and bicolors
Deadhead spent flowers to encourage continuous blooming. Water regularly but allow soil to dry between waterings. Feed with low-nitrogen, flower-promoting fertilizer monthly.
Decline
Variable; until first frost or end of seasonBlooming slows as temperatures drop; plants become leggy or decline with first frost
In warmer zones, cut back by one-third to rejuvenate. Allow flowers to set seed if desired for self-sowing next year. Remove at frost or before plants look too shabby.

Harvest Tips
