Growing Tips

  • Loosen soil 12 inches deep — carrots fork in compacted soil.
  • Mix seeds with sand for more even distribution.
  • Thin ruthlessly to 2–3 inches apart.
  • Keep soil surface moist until germination (10–21 days).
  • A light frost sweetens carrots — leave them in the ground until needed.

Common Mistakes

  • Adding fresh manure — causes forked, hairy roots.
  • Not thinning — #1 reason for small carrots.
  • Letting soil crust over during germination.
  • Harvesting too early — most varieties need the full 70–80 days.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
