Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with 2-4 true leaves emerge within 7-14 days. Very small and delicate.

Keep soil consistently moist but not soggy. Provide bright light and good air circulation to prevent damping-off. Thin seedlings if crowded.

2

Vegetative Growth

4-6 weeks

Plant develops bushy, compact growth habit with narrow, blue-green foliage and increasing branching.

Pinch back growing tips at 2-3 inches to encourage bushier form. Remove any dead or diseased foliage. Fertilize lightly every 2-3 weeks.

3

Flowering Initiation

2-3 weeks

Flower buds form at branch tips, appearing as small knots before opening into the characteristic fringed red blooms.

Maintain consistent watering and moderate fertility. Deadhead spent blooms to encourage more flowering. Ensure good air circulation.

4

Peak Bloom

8-12 weeks or until first frost

Plant produces abundant masses of small, deep red flowers with characteristic fringed petals and clove fragrance. Compact, mounding form fully visible.

Deadhead regularly to maintain continuous blooming. Water deeply but infrequently. Fertilize every 2-3 weeks with balanced or slightly lower nitrogen fertilizer.

5

Decline

Variable; continues until frost or extreme heat

Blooming slows as temperatures rise significantly in summer heat or as fall approaches with shorter days and cooler nights.

Cut back leggy plants by half to rejuvenate for fall bloom. Reduce fertilizing. In hot climates, provide afternoon shade.
