Seedling
2-3 weeksTiny plants with 2-4 true leaves emerging after germination. Delicate appearance with thin stems.
Keep soil consistently moist; provide bright indirect light under grow lights or in a sunny window. Begin fertilizing with half-strength liquid fertilizer every 2 weeks once true leaves appear.
Vegetative Growth
6-8 weeksBushy plants developing multiple stems and branches with lance-shaped green foliage. Roots establish and plant gains height and width.
Pinch back growing tips in early summer to encourage bushier, more compact growth. Provide full sun and maintain consistent moisture. Apply balanced fertilizer monthly.
Budding
3-4 weeksFlower buds form at stem tips in late summer. Plant appears fuller with visible clusters of tight, greenish buds along branches.
Reduce nitrogen fertilizer to avoid excessive foliage at expense of flowers. Maintain adequate water as buds develop. Support tall stems if needed.
Flowering
6-8 weeksProlific white daisy-like flowers with bright yellow centers bloom throughout the plant. Flowers open in succession from bottom to top of plant.
Deadhead spent flowers to encourage continued blooming. Water regularly as flowering increases plant water demands. Stake or support if plant becomes heavy.
Seed Development & Senescence
4-6 weeksFlowers fade; seed heads develop if flowers are not deadheaded. Foliage may yellow or show signs of aging. Plant energy shifts to seed production.
Leave some flowers for seed production and wildlife benefit, or deadhead to extend blooming. Cut back plant after hard frost or in early spring.
