Growth Stages

1

Seed germination

1-2 weeks

Seeds are tiny and require light to germinate. Small seedlings emerge with cotyledons.

Sow on soil surface and keep moist (not wet) until germination. Provide bright light. Germination takes 7-14 days at 65-70°F.

2

Seedling & establishment

3-4 weeks

Tiny plants develop their first true leaves and establish a root system. Growth is slow initially.

Thin seedlings to proper spacing. Keep soil consistently moist but not waterlogged. Grow in bright light. Fertilize sparingly or not at all.

3

Vegetative growth

4-6 weeks

Plant develops a bushy, mounding form with multiple stems and feathery foliage. Leaves are narrow and somewhat hairy.

Water moderately during dry spells. Reduce watering as plant establishes. Pinch back stems early to encourage bushiness. Avoid excessive fertilizer.

4

Flowering

6-12 weeks or more, depending on variety and conditions

Abundant daisy-like flowers with thin, delicate petals bloom on upright stems. Blooms are 0.5-1 inch across in clusters.

Deadhead spent flowers to extend blooming season. Water during dry periods. Provide support for taller varieties if needed.

5

Seed production & dormancy

Varies; perennials dormant in winter

Flowers fade and develop feathery seed heads. Plant may decline as seasons change or heat increases.

Allow some flowers to remain for seeds and wildlife. Trim back dead foliage in fall or early spring. Perennial types will regrow; annuals complete their life cycle.
