We regularly test seed quality and germination as lots move through storage and packing. We stand behind the seed we send and want customers to contact us when a packet does not perform as reasonably expected.

1-year seed warrantyCoverage begins on the date of purchase.

When properly stored, planted, and cared for, we guarantee reasonable germination and true-to-type growth for one year from the date of purchase.

What to expect from Red Arrow Radish Seeds

Red Arrow is best known for vivid red stems at the young seedling stage, but it can also develop an elongated, daikon-type root. Pink skin surrounds white flesh with a mild radish bite, giving the garden harvest an appeal beyond its colorful greens. Grow spaced plants for roots to slice, grate or add to salads. Harvest promptly while crisp, since leaving radishes too long in warm or dry soil reduces quality.

Growing facts

  • Botanical name: Raphanus sativus
  • Maturity or display: About 40 days for roots
  • Mature size: Size varies with harvest stage; allow the stated plant spacing
  • Spacing: 6 in between plants; rows 24 in

About the variety

Red Arrow was selected for conspicuously red young stems and is widely sold for microgreens. The supplier also describes mature pink-skinned, white-fleshed daikon-type roots. The root harvest is separate from the much earlier seedling harvest.

Starting seed

Direct sow 1/2 in. deep in late summer for cool-weather roots. Keep moist; allow 4-10 days to sprout. Thin to 6 in. apart, rows 24 in. apart. Use full sun and loose, fertile soil; water steadily.

Care through the season

Deep, stone-free soil helps roots develop evenly. Keep moisture consistent and weed gently to avoid root damage. Late-summer plantings are generally better for winter radishes than increasing spring daylength; thin crowded plants promptly.

Harvest and use

Pull crisp roots around 40 days, before they turn pithy. Remove tops and refrigerate. For seed, retain typical plants through flowering, allowing a cold period if needed; isolate radish varieties and dry mature pods.

Saving seed

Radishes cross readily through insect pollination. Save from several healthy, typical roots, keeping them through any needed winter chilling and the following flowering period. Isolate from other flowering radishes, dry fully mature pods, then shell, clean and label the seed.

Common problems

Flea beetles injure leaves and root maggots can tunnel into roots. Use insect netting early and rotate the bed. Crowding, drought, heat and delayed harvest can cause poor roots, excessive pungency or pithiness.
