Growth Stages

1

Seed Germination

7-14 days

Tiny seeds germinate with light exposure over 7-14 days at temperatures of 65-70°F. Seedlings emerge with delicate cotyledons.

Do not cover seeds; provide bright indirect light. Keep soil moist. Ensure good air circulation to prevent damping off.

2

Seedling Development

2-3 weeks

True leaves develop and seedlings form a small rosette of foliage. Growth is relatively slow at this stage.

Maintain consistent moisture and bright light. Thin seedlings if necessary. Avoid overwatering to prevent fungal issues.

3

Vegetative Growth

3-4 weeks

The plant develops a compact, bushy form with dense green foliage. Branching begins and the plant fills out its designated space.

Pinch back tips early to encourage bushier growth. Maintain regular watering and apply balanced fertilizer every 2-3 weeks.

4

Flowering

6-12 weeks (or until frost)

Small, brightly colored snapdragon-like flowers appear abundantly across the compact plant in a spectrum of colors. Blooms are 0.5-1 inch in size.

Deadhead spent flowers regularly to encourage continuous blooming. Provide weekly fertilizer with higher phosphorus. Keep soil moist but not soggy.

5

Decline

Variable; frost-sensitive annual

As temperatures rise in summer or after first frost, flowering slows and foliage may become stressed. Plant may look tired or leggy.

In cool climates, deadheading and proper care can extend bloom time. In hot areas, provide afternoon shade. Plant will cease flowering at first frost.

Harvest Tips
