Tips on How to Grow Snapdragons from Seeds

Germination

• Optimum conditions for seedling development that begins the day the crop is sown until cotyledon expansion.

• Germination is in  10 – 21 days.

• SOW INDOORS 8-10 weeks before last frost. 10-21 days to germinate. Direct Sow is not recommended.

• Do Not Cover Seeds, just press lightly into very moist soil and maintain moisture levels. If you are watering indoors do so from below, (sub-irrigate.) Keep at 68-75°F. 

• Grow on at 60°; warmer temperatures cause leggy transplants. Set out after danger of frost, spacing at 9–12". Perennial in Zone 7-10, grown as an annual.

• Light is necessary for germination. 
• TRANSPLANT into your outdoor garden after danger of frost. For Dwarf varieties 6-8 inches apart, tall varieties 12-18 inches apart. 
• Moisture: Very moist for days 1 – 3 or until radicle emergence. On days 4 – 7 reduce moisture to moist . Once actively growing, begin alternating between moisture levels wet and medium . Allow media to approach dry before re-saturating to level.
• Light: Full sun.
