Autumn King Organic carrot seeds are CERTIFIED ORGANIC! Excellent, straight, tapered roots with wide shoulders and a pointed end make Autumn King imperator carrots the best choice for late planting. Expect carrots 25-30cm (10-12″) long. Sow seeds from spring into late August, but cover your later plantings with lightweight row cover to protect from fall carrot rust flies. Harvest right through winter by leaving them in the ground. If heavy frost is forecast, either harvest for winter storage or processing, or mulch with a thick layer of straw. Carrots can also be harvested and stored in a cool place in ground peat moss, sawdust, or sand.
