Look to ensure a distance
1.95 feet (60.0 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
25°C / 77°F to ensure good germination.
By our calculations, you should look at sowing CBG Cone 2 about 56 days before your last frost date.
