Growth Stages

1

Seedling

2-3 weeks

Tiny green seedlings emerge with first true leaves appearing 7-10 days after germination

Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation to prevent damping off. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Vegetative Growth

3-4 weeks

Plant develops bushy foliage with multiple stems forming a compact mound, 6-12 inches tall

Pinch back growing tips when plants are 3-4 inches tall to encourage branching. Water at soil level and maintain consistent moisture. Begin fertilizing lightly every 2-3 weeks.

3

Budding

2-3 weeks

Flower buds form at branch tips, initially appearing as tight green clusters

Increase fertilizer frequency (balanced formula, moderate nitrogen). Ensure consistent watering as buds develop. Remove any diseased or yellowing foliage.

4

Flowering

6-12 weeks (depending on conditions)

Ruffled pink flowers open in succession, creating continuous color from blooming until frost or heat stress

Deadhead spent flowers regularly to promote continuous blooming. Reduce nitrogen fertilizer to encourage more flowers than foliage. Water at base of plant during hot weather.

5

Decline/Senescence

Variable

Flowering slows during extreme heat or cold; plant may appear stressed or produce fewer blooms

Provide afternoon shade in very hot climates. Cut back by one-third if plant becomes leggy. In mild climates, may rejuvenate with cooler fall temperatures.
