Try to aim for a seed spacing of at least
0.98 inches (2.5 cm) and sow at a depth of around
0.25 inches (0.64 cm). Soil temperature should be kept higher than
20°C / 68°F to ensure good germination.
By our calculations, you should look at sowing Unique Mix about 28 days before your last frost date.
As Unique Mix is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
The botanical epithet is from the Latin bipinnatus meaning “staunch” or “like two small wings”.
