Growth Stages

1

Seedling

2-3 weeks

Tiny green seedlings with first true leaves emerge; very delicate appearance

Keep soil consistently moist but not soggy. Provide bright, indirect light. Maintain 65-70°F temperature.

2

Vegetative Growth

4-6 weeks

Plant develops bushy form with increasing stems and fine, linear foliage; no buds yet

Pinch back stem tips in early summer to encourage branching and bushier habit. Water regularly. Begin light fertilizing with balanced fertilizer every 2-3 weeks.

3

Budding

2-3 weeks

Numerous small flower buds appear at stem tips; plant becomes dense and rounded

Continue regular watering and feeding. Ensure full sun exposure. Monitor for powdery mildew and improve air circulation if needed.

4

Flowering

6-8 weeks

Profusion of small white daisy flowers cover the compact mound; peak bloom in fall (September-November)

Deadhead spent flowers to extend bloom. Reduce nitrogen fertilizer to encourage more flowers over foliage. Water at soil level.

5

Senescence

3-4 months

Flowers fade; foliage yellows and plant begins dormancy in late fall and winter

Cut back to 3-4 inches above ground in late fall or early spring. Divide every 3-4 years to maintain vigor. Minimal watering needed.
