How to Grow White Globe Radishes From Seed

Updated July 2026

White Globe is a round, all-white radish with smooth skin and crisp, mild white flesh. Unlike the fiery reputation of some radishes, it offers a clean, gentle bite that appeals to those who find red radishes too sharp. It matures in about 28 days and makes a striking pure-white addition to salads and platters. Easy and quick, it is a lovely change from the usual red globes.

This is the quick guide to White Globe. 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 White Globe seeds half an inch deep and one inch apart in cool spring or fall soil. Thin seedlings to about 2 inches apart and keep the soil evenly moist. Harvest the round white roots at about 28 days, once they reach an inch across, for the mildest, crispest flesh.

Best tip

White Globe is prized for its gentle, mild flavor, but that mildness fades if the roots grow slowly or sit too long. Sow in cool spring and fall weather, keep the soil evenly moist so they never stall, and pull them promptly at about an inch across. In warm climates, grow it as a spring and fall crop to avoid heat-driven sharpness and bolting.
