Germination

1-2 weeks

Tiny seedlings emerge with cotyledons (seed leaves), requiring 7-14 days at temperatures of 65-75°F

Keep soil moist but not waterlogged. Provide bright light. Avoid fungal damping-off with good air circulation.

2

Seedling & Early Growth

3-4 weeks

First true leaves develop; plants grow slowly but steadily with characteristic narrow, blue-green foliage

Maintain cool, bright conditions. Thin seedlings to proper spacing. Reduce watering frequency slightly.

3

Vegetative Growth

2-3 weeks

Plant develops bushy, compact form with dense foliage before flowering begins

Pinch growing tips early to encourage branching and fuller shape. Reduce nitrogen to promote flowering.

4

Flowering

8-12 weeks (continuous until frost)

Abundant small flowers appear in clusters; blooms are fragrant, 0.5-1 inch across in various colors

Deadhead spent flowers regularly to extend bloom. Provide consistent water during flowering. Avoid overfeeding.
