Try to aim for a seed spacing of at least
3.12 inches (8.0 cm) and sow at a depth of around
0.49 inches (1.25 cm). For optimal germination, soil temperature should be a minimum of
8°C / 46°F.
By our calculations, you should look at sowing Teton Hybrid about 60 days before your last frost date.
Teton Hybrid is half hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside - as a guideline, the minimum temperature outside should be approximately 0°C / 32°F.
