As soon as the soil can be worked, sow seeds 1/2" deep, 3 seeds per inch, in rows 18-24" apart. Soil should be well-worked and loose. Allow 18 days for germination. Plant every two weeks for a continuous supply. Thin to 4-6 plants per foot. Plant carrots intended for winter use(storage) about 3 months before the first fall frost. Dig roots before the ground freezes. A packet contains approx. 1,000 seeds, unless otherwise stated. One oz. contains 20,000 seeds and sows 250 ft. of row.
Carrot Growing Hints: When starting carrots, plant some radish seeds with them as a nurse crop. The radishes will help mark the row so you can do some weeding before the carrots emerge. This also gives you radishes without using a separate row to grow them.
