Daucus carota 'Atomic Red'
vegetableAtomic Red is a striking heirloom Imperator-type carrot with bright coral-red skin, a deep red core, and feathery green tops. The red color comes from lycopene, the same carotenoid that colors tomatoes and watermelon. Roots reach 8 to 11 in. long and are slender, tapered, and crisp; flavor is mild and sweet raw and noticeably richer cooked, when heat releases more of the lycopene.

When to Fertilize
Light feed pre-plant only
Fertilizer
Low-nitrogen 5-10-10 or compost; avoid fresh manure
Direct sow Atomic Red 2 to 4 weeks before the last spring frost in deeply worked, stone-free, sandy loam - long Imperator carrots especially need deep loose soil to grow straight. Sow 1/4 inch deep in rows 12 to 18 inches apart and keep soil moist until germination, which takes 14 to 21 days. Thin to 2 inches apart in the row once seedlings have a few true leaves. Do not over-fertilize; excess nitrogen causes the slender Imperator shape to fork or grow hairy.

Good neighbors that attract beneficial insects or deter pests
Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Cover the bed with insect netting from sowing to harvest, especially in spring and fall, and interplant with strongly scented onions or leeks
Hose off occasional clusters and support beneficial insects with nearby alyssum or yarrow
Avoid sowing carrots in beds that were sod the previous year; rotate annually
Loosen soil deeply, remove stones, and avoid heavy fresh manure or excess nitrogen
Pull Atomic Red about 70 to 75 days from sowing, when shoulders reach about 1 inch across. Cook these to bring out their full flavor and color - the red pigment is more available cooked, and the texture turns velvety. Lightly steamed, roasted with olive oil, or simmered into stew all work better than raw, though they are still good in slaw.
Atomic Red trades some of the orange carrots beta-carotene for lycopene, the same carotenoid that colors tomatoes and watermelon and is linked to heart and prostate health. Cooking with a little oil makes the lycopene much more bioavailable, so a tray of roasted Atomic Reds gives more usable lycopene than the same weight raw. The roots still supply vitamin K, potassium, and fiber.
