How To Grow Nemesia From Seeds

Temperatures:

• Germination (Stage 1): 65 to 72°F (18 to 22°C)
Germination is more uniform under cooler temperatures of 65°F (18°C)

• Cover the seed lightly with coarse vermiculite.
• Germination takes 4 to 5 days.
• Cotyledon stage (Stage 2): 65 to 72°F (18 to 22°C)
• True leaves (Stage 3): 65 to 70°F (18 to 21°C)
• Hold plugs (Stage 4): 62 to 65°F (16 to 18°C)

Light

• Stage 1: Light is not required for germination.
• After germination, Stages 2 to 3: 1,000 to 2,500 f..c.
• Seedling maturity, Stage 4: Up to 5,000 f.c., if temperature can be controlled.

Humidity

• Maintain 95% relative humidity through radicle emergence.

Soil Moisture

• Keep soil moisture high until radicle emergence, then reduce moisture levels after the radicle penetrates the medium. Do not allow the seedlings to wilt.

Fertilizing

• At radicle emergence: Apply 50 to 75 ppm N from 14-0-14 or 13-2-13, alternating with 20-10-20 type fertilizer.
• As cotyledons expand: Increase to 100 to 150 ppm N.

Growing On to Finish

Media

• Use a well-drained, disease-free, soil less medium with a pH of 5.5 to 6.2 and a medium initial nutrient charge.

Temperature

• Nights: 55 to 62°F (13 to 17°C)
• Days: 62 to 68°F (17 to 20°C)

Light

• Maintain light level as high as possible while maintaining moderate temperatures. The higher the light, the faster the flowering and the stronger the stem.

Irrigation

• Avoid both excessive watering and drought. Do not allow plant to wilt.

Fertilizer

• Apply 150 to 200 ppm N once a week, alternating between 15-5-15 and 20-10-20 type fertilizers. Supplement with iron if needed. Maintain the media EC at 1.0 to 1.5 mmhos/cm. and pH at 5.8 to 6.2.
