Growth Stages

1

Germination & Seedling

10-14 days

Tiny seedlings with first true leaves appearing; very delicate

Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing to prevent damping off.

2

Vegetative Growth

3-4 weeks

Bushy plants developing multiple stems and narrow, blue-green foliage; no flowers yet

Pinch back growing tips when 3-4 inches tall to encourage branching. Light fertilizing with balanced formula (once weekly or every other week). Ensure good air circulation.

3

Budding & Early Flowering

2-3 weeks

Flower buds forming at branch tips; first blooms opening in the intended color

Reduce nitrogen to encourage more flowers; use phosphorus-rich fertilizer. Deadhead spent flowers immediately to promote continuous blooming. Water consistently.

4

Peak Flowering

6-10 weeks or more

Plant covered in abundant small, ruffled flowers; strong fragrance if variety has it

Deadhead regularly every 2-3 days. Water moderately and maintain good drainage. In heat, provide afternoon shade. Feed sparingly with low-nitrogen fertilizer every 2-3 weeks.

5

Decline (Late Summer/Fall)

Variable

Flowering may slow in peak summer heat; plant may rest before fall rebloom in cooler climates

Cut back spent growth if needed; water less if temperatures drop. In mild climates, may continue blooming into fall; in hot climates, may benefit from a summer rest and return vigor in cooler weather.
