Growth Stages

1

Seedling

2-3 weeks

Tiny green cotyledons emerge and develop into small seedlings with true leaves. Plants are delicate and tender.

Maintain consistent moisture and humidity (70-75%). Provide gentle air circulation. Keep soil warm (70-75°F). Begin very dilute fertilizing at 2-3 weeks.

2

Vegetative Growth

3-4 weeks

Plants develop bushy, compact growth with multiple branching stems and glossy green foliage. No flowers yet.

Maintain moist soil and consistent shade. Pinch back growing tips at 3-4 weeks to encourage bushier growth. Apply balanced fertilizer every 2 weeks. Monitor for spider mites in dry conditions.

3

Flowering

8-12 weeks or until frost

Bicolor flowers appear with contrasting petal colors (typically pink/white, red/white, or orange/white combinations). Continuous blooming begins.

Continue consistent watering and humidity. Deadhead spent flowers to encourage continuous blooming. Switch to higher phosphorus fertilizer (5-10-10) every 2 weeks. Maintain partial shade to prevent color fading.

4

Peak Bloom

6-10 weeks or longer

Plant is fully covered in abundant bicolor flowers creating a colorful mound. Flowering is prolific.

Maintain even moisture levels. Deadhead regularly. Watch for powdery mildew in humid conditions; ensure good air circulation. Continue feeding every 2 weeks.

5

Decline/Frost Damage

Until first frost (varies by region)

Flowers and foliage deteriorate with cool temperatures and first frost. Plant dies back completely.

Enjoy flowering until temperatures drop below 55°F at night. Pull plants when killed by frost. Can collect seed capsules before frost if saving seeds.

Common Pests

  • Increase humidity by misting foliage, spray with water to dislodge, use neem oil or horticultural oil spray every 7-10 days

  • Yellow sticky traps, insecticidal soap, neem oil, or pyrethrin spray; inspect undersides of leaves regularly

  • Strong water spray, insecticidal soap, neem oil, or reflective mulches

  • Isolate affected plants, dab insects with alcohol-soaked cotton swab, spray with neem oil or insecticidal soap

Harvest Tips

Deadhead (remove spent flowers) regularly to promote continuous blooming and prevent seed set. Pinch flowers just below the base of the bloom. For seed collection, allow seed capsules to mature on the plant until they appear slightly translucent and ready to pop, then carefully collect before they disperse. Seeds can be stored in a cool, dry place for future seasons.
