Start indoors six to eight weeks before last frost date.
Look to ensure a distance 1.95 inches (5.0 cm) between seeds when sowing - bury at a depth of at least 0.2 inches (0.5 cm) deep. Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.By our calculations, you should look at sowing Santa Fe Grande about 38 days before your last frost date.
