How to Grow Imperator 58 Carrots From Seed

Updated July 2026

Imperator 58 is the long, slender carrot you know from the supermarket, a bright-orange root that tapers to a point and reaches 8 to 10 inches. It matures in about 70 to 75 days and needs deep, loose soil to grow that length straight and smooth. Sweet and crisp, it is a classic all-rounder for fresh eating and cooking. Give it a well-dug bed and you will grow long, handsome carrots at home.

This is the quick guide to Imperator 58. For the full step-by-step on starting seeds, sowing, feeding, and troubleshooting carrots, see our complete guide to growing carrots from seed.

Quick start

Sow Imperator 58 seed directly a quarter inch deep in deep, loose, stone-free soil, since these long roots need room to grow straight. Keep the surface moist through the 14 to 21 day germination, then thin to 2 to 3 inches apart. Water evenly and steadily. Harvest the long, slender orange roots in about 70 to 75 days.

Best tip

Imperator 58 only reaches its long, classic shape in deep, loose soil, so dig the bed at least 10 to 12 inches down and clear every stone, or grow it in a deep raised bed. In heavy or shallow ground the long tips fork, so if that is your soil, choose a shorter type like Chantenay instead. Water consistently, since dry spells make long carrots woody.
