Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with cotyledons emerge; first true leaves are narrow and slightly fuzzy.

Keep soil lightly moist but well-draining. Provide bright light. Avoid overwatering to prevent damping off.

2

Vegetative Growth

3-4 weeks

Plant develops rosette of narrow, silvery-green foliage. Stems lengthen and become sturdier.

Water moderately; reduce frequency as plant establishes. Do not fertilize heavily—lean soil encourages better flowering. Transplant when 3-4 inches tall.

3

Budding & Early Flowering

2-3 weeks

Flower buds form on long stems above the foliage. First blooms appear in bright yellow.

Continue moderate watering. Stop fertilizing or use low-nitrogen formula. Deadhead spent flowers to encourage continuous blooming.

4

Peak Flowering

8-12 weeks

Plant produces abundant large daisy-like flowers with dark centers and prominent yellow petals. Flowers open fully in bright sun.

Maintain regular deadheading. Water only during prolonged drought. Minimal fertilizer needed. Flowers close at dusk and on overcast days.

5

Decline & Over-winter (perennial zones)

2-4 months

Flowering may slow in cooler months. Plant may go dormant in zones 9-10 during winter.

Reduce watering significantly. No fertilizer needed. Prune back by one-third to half in late winter to promote spring growth. In colder zones, treat as annual or bring indoors.
