Growth Stages

1

Seedling

2-3 weeks

Tiny seed germinates (10-15 days), producing first true leaves. Growth is initially slow and compact.

Keep soil moist but not waterlogged. Provide bright light and maintain 70-75°F. Do not cover seeds heavily.

2

Vegetative Growth

3-4 weeks

Plant develops multiple stems and branches, forming a bushy, compact mound with small green leaves.

Begin light fertilizing weekly with balanced fertilizer. Pinch growing tips at 2-3 weeks to encourage branching. Maintain consistent moisture.

3

Early Flowering

1-2 weeks

First delicate pink flowers appear at branch tips, small and loosely spaced initially.

Continue weekly fertilizing with lower nitrogen formula (e.g., 5-10-10). Deadhead spent blooms to encourage more flowers. Increase watering as plant matures.

4

Peak Flowering

8-12 weeks (or longer with proper care)

Plant becomes completely covered in masses of small pink blooms, creating a full, cascading appearance.

Maintain consistent watering and feeding. Deadhead regularly to sustain blooming. Watch for pests and diseases in humid conditions. Trim back leggy stems if needed.

5

Late Season/Dormancy

Variable, depends on climate and care

Flowering gradually slows as temperatures cool or day length shortens. Plant may become less vigorous.

Reduce fertilizer frequency. Bring indoors in frost-prone areas or treat as annual. Cut back spent growth if overwintering. Reduce watering in dormancy.
