Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout in 7-14 days under moist conditions. Tiny seedlings develop first true leaves.

Maintain 70-75°F soil temperature. Provide bright, indirect light. Keep soil moist with bottom watering to avoid damping off.

2

Vegetative Growth

3-4 weeks

Plant develops bushy foliage with multiple stems and leaves. No flowers yet.

Pinch growing tips to encourage branching and bushiness. Maintain consistent moisture and humidity. Apply balanced fertilizer every 2 weeks.

3

Flowering

8-12 weeks or until frost

Pink and white bicolor flowers appear in the leaf axils. Blooms are prolific and continuous with proper care.

Deadhead spent flowers to encourage more blooms. Maintain steady moisture and warmth (65-75°F). Feed every 2 weeks with balanced or flower-promoting fertilizer.

4

Peak Bloom

4-8 weeks

Plant is covered with pink bicolor flowers. Dense flowering creates an impressive display.

Continue deadheading. Pinch back any leggy growth. Ensure adequate humidity and consistent watering. Watch for pests.
