Carrot seeds should usually be planted about 1/4 inch deep. In heavier or drier soil, you can go a little deeper—up to 1/2 inch —but don’t bury them much more than that, or germination can drop.

Quick Scoop

  • Best depth: 1/4 inch.
  • Heavier/drier soil: 1/2 inch max.
  • Later sowings in warm, dry soil: up to 3/4 inch in some guidance, but shallow is still safer for most home gardens.

Easy rule

If the seeds are tiny, think light cover, not deep planting. A fine layer of soil or compost is enough to keep moisture in while still letting the sprouts push through.

Small tip

Keep the topsoil evenly moist after planting, because carrot seeds germinate slowly and dry-out is one of the biggest reasons they fail.
