Heirloom / Open Pollinated Carrots grow best in well prepared, deeply worked, loose soil. Direct seed Carrots in full sun or part shade (in hot climates), from early spring-summer , ¼ – ½” deep, approx. 4 seeds per inch, in rows 12-16″ apart. Germination occurs in 6-21 days at temperatures of 50-75° F. Thin the plants to 1-3″ apart. To prevent green shoulders you can hill 1-2″ of soil around plants when 7-10 leaves have formed. A good mulch of organic material (such as grass clippings) is very beneficial once carrots are established. Harvest when Heirloom / Open Pollinated carrots have brightened in color, when color has deepened.
