Seedling
2-3 weeksTiny cotyledons emerge, followed by small true leaves. Plant is fragile and low to ground.
Keep soil consistently moist but not waterlogged. Provide bright light. Maintain warm temperature (70-75°F). Thin seedlings to proper spacing once true leaves appear.
Vegetative Growth
3-4 weeksPlant develops bushy, spreading mounding habit with increasingly dense foliage. Leaves are small, textured, and lance-shaped.
Pinch back growing tips early to encourage bushier branching and more flower buds. Reduce water frequency as plant matures. Feed with balanced or low-nitrogen fertilizer every 3-4 weeks.
Budding
1-2 weeksSmall flower buds form at branch tips. Buds are tightly clustered in flat-topped or slightly domed inflorescences.
Maintain consistent watering. Begin feeding with higher phosphorus fertilizer (bloom booster) to encourage flowering. Ensure full sun exposure.
Flowering
4-6 months (spring to fall frost)Small white flowers open in dense clusters (umbels). Blooms attract pollinators and cover much of the foliage. Plant reaches mature mounding size (12-18 inches wide, 8-12 inches tall).
Deadhead spent flower clusters regularly to encourage continuous blooming. Water when soil surface is dry. Feed every 2-3 weeks with bloom formula. Provide afternoon shade in extreme heat (above 95°F) to prevent flower fade.
Decline
Until frost or end of seasonFlowering slows or stops as temperatures drop below 50°F or as plant approaches frost. Foliage may discolor.
Cut back or allow frost to kill plant if growing as annual. In zones 8-10, prune back by 1/3 to 1/2 in late fall to encourage spring regrowth for next season. Reduce watering frequency.
