Planting Instructions for Radish Seeds

  1. Location: Choose a sunny spot with loose, well-drained soil. Radishes grow best in cool weather.
  2. When to Plant:
    • Spring Crop: Sow Todd’s Seeds Radish seeds 2–4 weeks before the last expected frost.
    • Fall Crop: Sow 6–8 weeks before the first expected frost.
    • For continuous harvests, sow every 7–10 days.
  3. Soil Prep: Loosen soil to a depth of 6–8 inches and remove stones. Ideal pH is 6.0–7.0. Add compost if the soil is poor.
  4. Sowing Depth: Plant seeds 1/2 inch deep.
  5. Spacing: Space seeds 1 inch apart in rows 12 inches apart. Thin to 2 inches apart once seedlings emerge.
  6. Watering: Keep soil consistently moist but not soggy. Inconsistent watering can cause cracking or a spicy flavor.
  7. Care: Mulch to retain moisture and suppress weeds. Avoid high-nitrogen fertilizers, which promote leafy growth over roots.
  8. Harvest: Harvest when roots are 1–2 inches in diameter, typically 20–30 days after sowing. Do not let them get oversized, or they will become woody and bitter.
