Germination
7-10 daysTiny seedlings with thread-like cotyledons emerge from soil surface
Keep soil consistently moist but not waterlogged. Provide bright light (grow lights or sunny window). Germination temperature 65-75°F ideal.
Seedling
2-3 weeksPlants develop fine, feathery foliage; remain small and delicate with minimal growth
Thin seedlings to proper spacing. Reduce watering frequency as roots develop. Avoid transplanting stress; grow directly in final location when possible.
Vegetative Growth
3-4 weeksBushy, mounding habit develops with dense feathery foliage; compact growth pattern
Pinch back stems early to encourage branching and bushier form. Maintain moderate watering. Begin fertilizing monthly with dilute balanced fertilizer if desired.
Flowering
8-12 weeks (until frost or end of season)Profusion of tiny golden-yellow daisy-like flowers cover the foliage; continuous bloom through season
Deadhead spent flowers to encourage continuous blooming. Reduce fertilizer to avoid excessive foliage at expense of flowers. Water during drought stress only.
Senescence
2-3 weeks before frost or season endFlowers decline and fade as temperatures cool or frost approaches; foliage may thin
Plant is frost-sensitive; pull up at season's end. In warm zones, may self-seed for next year if allowed to mature seeds.

Fun Facts
