Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with 2-4 true leaves emerge under bright, indirect light.

Keep soil moist and warm (70-75°F). Provide 14-16 hours of bright light daily. Avoid direct sun which can damage delicate seedlings.

2

Transplant/Establishment

2-4 weeks

Young plants develop a stronger root system and 4-6 true leaves. Growth becomes more vigorous.

Once 2-3 true leaves appear, thin seedlings or transplant to individual pots. Maintain consistent moisture and warm temperatures (65-75°F).

3

Vegetative Growth

3-4 weeks

Plant develops a full, branching form with dense foliage. The characteristic trailing habit becomes apparent.

Pinch back growing tips early to encourage bushier, more cascading growth. Continue to water consistently and feed every 2 weeks with diluted balanced fertilizer.

4

Flowering

8-12 weeks (until frost or season end)

Abundant small pink flowers (about 1 inch across) appear along trailing stems. Blooming becomes prolific and continuous.

Maintain even moisture and light feeding schedule. Deadhead spent flowers to encourage continued blooming. Provide afternoon shade in hot climates.

5

Peak & Decline

Variable; through season end

Flowering reaches its peak in mid-summer; may slow during extreme heat or cold nights. Foliage may thin in fall.

In zones 9+, plant may persist through winter indoors or in protected locations. Move containers to shadier spots during peak heat. Cut back and overwinter indoors if desired.
