Plant seeds in early spring as soon as the soil can be worked. Continue planting every 3 weeks until mid-summer. Before planting, till in compost or peat moss and remove all exposed clods and stones. Sow seeds sparingly, firm soil gently over the row and keep moist.
Keep soil deeply and evenly watered. Control weeds with shallow hoeing. Fertilize once a month.
For peak flavor and texture, dig carrots anytime after they've developed deep color.
