How To Grow Snapdragons From Seeds

Germination

Stage 1:

Use a well-drained, disease-free seedling medium with a pH of 5.5 to 5.8
Germination: 64 to 68�F (18 to 20�C)
Timing: 4 to 8 days
Soil temperature: 64 to 68�F (18 to 20�C)
Moisture: Medium
Light: Not required
Cover: Lightly with vermiculite

Plug Production

Stage 2:

Timing: 7 to 14 days
Soil temperature: 65 to 70�F (18 to 21�C)
Moisture: Reduce moisture levels once radicle emergence occurs. Allow the soil to dry out slightly before watering. Irrigate early in the day so that foliage is dry by nightfall.
Light: 450 to 1,500 f.c.
Fertilizer: 50 to 75 ppm N from 14-0-14 or calcium/ potassium nitrate feed once per week when cotyledons are fully expanded. Alternate feed with clear water. Maintain water alkalinity at 60-100 ppm and ammonium levels at less than 10 ppm.
Soil pH: 5.5 to 5.8

Stage 3:

Growth and development of true leaves.

Timing: 14 days
Soil temperature: 62 to 65�F (17 to 18�C)
Moisture: To promote root growth and control shoot growth, allow the soil to dry between irrigations, but avoid wilting.
Light: 1,000 to 2,500 f.c.
Fertilizer: 100 to 150 ppm of 20-10-20 alternating with 14-0-14 or other calcium/potassium nitrate fertilizer, every two or three irrigations. Supplement with magnesium one to two times during this stage using magnesuium sulfate (16 oz./100 gal.) or magnesium nitrate. Do not mix magnesium sulfate with calcium nitrate as precipitate will form.
Soil pH: 5.5 to 5.8

Stage 4:

Plants are ready for transplanting.

Timing: 7 days
Soil temperature: 60 to 62�F (16 to 19�C)
Moisture: Allow soil to dry thoroughly between irrigations, but avoid wilting.
Light: 1,000 to 2,500 f.c.
Fertilizer: 100 to 150 ppm N from 14-0-14 or calcium/ potassium nitrate feed as needed. Avoid ammonium fertilizers in Stage 4.
Soil pH: 5.5 to 5.8

Growing On to Finish-In Greenhouse or Outdoors

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

Temperature: 45 to 55�F (10 to 13�C) nights and 55 to 70�F (13 to 22�C) days. Avoid night temperatures above 55�F (13�C) as this will reduce stem strength.
The best time to grow Snapdragons is Autumn through early Spring, when cooler growing conditions can be maintained.
Moisture: Allow soil to dry slightly between waterings, but avoid wilting.
Light: Keep light levels as high as possible while maintaining recommended temperature.
Fertilizer: Every other irrigation, apply 150 ppm N from 15-0-15, alternating with 20-10-20. Alternate feed with clear water.
Soil pH: 5.5 to 6.2

Controlling Height:

Once plants are rooted to the sides of the containers they can be allowed to dry slightly prior to irrigation.
Withhold fertilizer, especially phosphorous and ammonium-form N.
Snapdragons are responsive to day/night temperature differential (DIF) and are shorter with a negative DIF.
