Comet Radish Seeds (Raphanus sativus) – 200+ Non-GMO Heirloom Seeds for Planting, Crisp Round Roots with Bright Color, by Isla’s Garden Seeds, Gift Idea for Gardeners

Comet Radish (Raphanus sativus) is a fast-maturing heirloom that produces uniform, bright-colored round roots with snappy crunch and mild, peppery flavor. Excellent for quick salads, snack plates, and crunchy garnishes straight from the garden.

A cool-season staple, Comet is ready in just 25–30 days and performs best in spring and fall. Compact plants form crisp roots reliably when grown in loose, evenly moist soil—perfect for beds, raised planters, and succession sowing every couple of weeks.

Enjoy roots small for extra tenderness or allow to size up while maintaining good texture. The leafy tops are edible, too—use young greens sautéed or in mixed salads for an added garden-fresh boost.

Dependable, speedy, and delicious, Comet Radish delivers continuous harvests and vibrant color, making it an ideal choice for new and experienced gardeners alike.

Direct sow as soon as soil can be worked in spring, or late summer for fall crops. Choose a sunny site with loose, well-draining soil; remove stones and clods to promote smooth, round roots. Keep sowings small and frequent for steady harvests.

Sow seeds 1/2 inch deep in rows 8–12 inches apart. Keep the top inch of soil evenly moist for quick germination (3–7 days). When seedlings have true leaves, thin to 2 inches apart—crowding leads to small or misshapen roots.

Grow quickly for best flavor and texture: maintain even moisture and harvest promptly at desired size. Provide light shade or mulch in warming weather to prevent pithiness and encourage crisp, juicy roots.
