Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with first true leaves appearing. Very delicate and susceptible to damping off.

Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation. Avoid overhead watering.

2

Vegetative Growth

3-4 weeks

Young plants developing multiple stems and leaves, becoming bushier. No flowers yet.

Pinch tips early to encourage branching. Water regularly but allow some drying between waterings. Begin hardening off if growing indoors.

3

Budding

1-2 weeks

Plant reaches full size with visible flower buds forming at branch tips.

Reduce nitrogen fertilizer; switch to balanced or bloom-promoting fertilizer. Maintain consistent watering schedule.

4

Flowering

8-12 weeks (or until frost)

Dense clusters of small purple flowers blooming continuously across the plant.

Deadhead spent flowers regularly to encourage continued blooming. Water at soil level, not overhead. Apply balanced fertilizer every 2-3 weeks.

5

Mature/Decline

Variable until frost

Flowering continues but may slow in extreme heat or if plant becomes stressed. Annual dies at first frost.

Continue deadheading. In zones 9+, prune back lightly in summer to rejuvenate for fall blooming. Provide afternoon shade in very hot climates.
