Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with first true leaves emerging; delicate and requiring protection

Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Maintain temperatures 65-75°F.

2

Vegetative Growth

3-4 weeks

Plant develops multiple stems and foliage; bushy growth pattern forming

Water moderately, pinch back tips to encourage bushiness. Fertilize every 2-3 weeks with balanced fertilizer.

3

Budding

2-3 weeks

Flower buds begin to form at stem tips; plant reaches mature size

Continue regular watering and feeding. Provide full sun for prolific flowering. Reduce nitrogen fertilizer.

4

Flowering

6-12 weeks or longer

Vibrant blooms open in succession; continuous flowering with proper care

Deadhead spent flowers to encourage more blooms. Maintain consistent watering. Continue fertilizing with lower-nitrogen formula.

5

Senescence/Decline

Variable, until frost or end of season

Flowering slows; plant may decline in cooler climates or with frost

In warm zones, light pruning can rejuvenate growth. In cooler climates, prepare to replant annually.
