How to Grow Red Arrow Radishes From Seed

Updated July 2026

Red Arrow is an early, vigorous radish that produces uniform, round, bright-red roots with crisp white flesh. Bred for speed and dependability, it germinates strongly and sizes up evenly in about 25 days, even in cooler soils. Its consistent shape and reliable performance make it a favorite for succession sowing. Red Arrow delivers a clean, mild, peppery crunch that is perfect for everyday salads.

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

Quick start

Direct-sow Red Arrow seeds half an inch deep and one inch apart in cool spring or fall soil; it germinates strongly even in cool ground. Thin seedlings to about 2 inches apart and keep the soil evenly moist. Harvest the uniform round red roots at about 25 days, once they reach an inch across.

Best tip

Red Arrow's vigor and early maturity make it perfect for succession sowing, so plant a fresh short row every couple of weeks in cool weather for a steady supply. Keep the soil evenly moist so the roots stay crisp and mild, and pull them promptly. In warm regions, grow it as a spring and fall crop to avoid summer bolting.
