Growth Stages

Germination

7-14 days

Tiny seedlings emerge with cotyledons (seed leaves), appearing as small green points

Keep soil consistently moist but not waterlogged. Maintain temperatures 60-70°F. Ensure bright light exposure. Thin seedlings to proper spacing.

Seedling/Vegetative

3-4 weeks

Small plants develop true leaves and establish a bushy, compact habit with multiple stems

Provide 6+ hours of bright light daily. Water regularly to keep soil moist. Begin light fertilizing every 2-3 weeks with balanced fertilizer. Pinch growing tips for bushier plants.

Pre-flowering

1-2 weeks

Plant becomes fuller and stockier; flower buds begin forming at stem tips

Continue regular watering and fertilizing. Ensure adequate light. Remove any dead or diseased foliage. Maintain moderate temperatures 60-75°F.

Flowering

6-12 weeks or longer

Dense clusters of small, fragrant violet-purple flowers appear and continuously bloom in waves

Deadhead spent flowers to encourage continuous blooming. Water consistently at soil level. Reduce nitrogen fertilizer; use balanced or low-nitrogen fertilizer. Provide light shade in intense heat.

Peak Bloom/Decline

Variable, season-dependent

Maximum flower production in cool weather; flowering may slow in extreme heat or cold

Continue deadheading. In midsummer heat, plants may reduce flowering; resume vigor in cooler fall temperatures. Pinch back leggy growth to rejuvenate. Reduce watering slightly in fall.
