You should plant carrots in cool weather, either in early spring or late summer for a fall crop.

Quick Scoop

  • In most climates, sow carrot seeds 2–4 weeks before your last spring frost , as soon as the soil can be worked and has warmed to at least about 50°F (10°C).
  • Carrots are a cool-season crop and grow best with soil temperatures around 55–75°F, which helps seeds germinate well and roots develop straight and sweet.
  • For a sweeter harvest, many gardeners sow again about 10 weeks before the first fall frost , so the roots mature in cool weather and can even get sweeter after light frosts.
  • In milder or warm regions (like much of the southern U.S.), carrots can often be sown in late summer or even fall and grown through winter, as long as extreme heat is avoided.
  • A simple rule of thumb: direct-sow outdoors 4–6 weeks before your average last frost for spring carrots, then again in mid to late summer for a fall harvest, repeating small sowings every few weeks if you want continuous picking.

If you tell me your growing zone or region, I can narrow this down to specific calendar dates for when you should plant carrots in your area.
