You should plant them in early spring as soon as the soil can be worked, or in late summer for a fall harvest. Ideal soil temperatures for germination range from 50 F to 75 F. Sow seeds directly in the garden about 1/8 inch deep. Carrot seeds are small, so mix them with sand for easier sowing 1st class mail is used so there is no tracking. If you prefer tracking i recommend paying the extra fee for upgraded shipping which is 1 fee for as many packs of seeds as you want and alot quicker delivery Be sure to check out my shop for alot of other vegetable and fruit seeds
