Growth Stages

1

Germination & Seedling

7-14 days germination; 3-4 weeks to sturdy seedlings

Tiny seeds sprout under warm, humid conditions. First true leaves appear delicate and narrow.

Maintain 70-75°F soil temperature. Provide bottom heat with a heating mat. Keep humidity high with clear covers. Mist gently to prevent drying. Ensure bright indirect light.

2

Vegetative Growth

6-8 weeks

Plant develops multiple pairs of true leaves and establishes a stronger root system. Growth is relatively slow and steady.

Maintain consistent moisture. Begin fertilizing weekly with half-strength balanced fertilizer. Provide 14-16 hours of bright light daily. Ensure good air circulation to prevent damping off.

3

Pre-Flowering & Budding

3-4 weeks

Plant becomes bushier and develops visible flower buds at stem tips. Buds swell and show color.

Continue consistent watering and fertilizing. Provide full sun exposure. Support tall stems with stakes or cages if needed. Maintain warm temperatures (65-72°F at night).

4

Flowering & Blooming

4-6 weeks or longer

Large, spectacular picotee flowers open gradually, displaying deep blue-purple petal edges with cream or white centers. Multiple blooms appear on each stem.

Maintain even moisture; drought stress can reduce bloom quality. Remove spent flowers to encourage continued blooming. Reduce nitrogen fertilizer; switch to higher phosphorus formula to support blooming. Cut flowers in early morning for best vase life.

5

Senescence & Decline

Variable; extends into fall

Flowers fade and drop. Plant gradually declines as it exhausts energy reserves.

Deadhead spent blooms to extend flowering. Reduce watering gradually. In warm zones, plant may regrow if cut back. In cooler zones, treat as annual and compost spent plant.
