when to plant carrots

You can plant carrots twice a year in most climates: in early spring a few weeks before your last frost, and again in late summer to early fall about 10 weeks before your first hard frost.

Quick Scoop

Best general timing

  • Sow carrot seeds 2–3 weeks before your last spring frost so they grow into the cool late spring and early summer weather.
  • For a fall crop, sow them about 10 weeks before your first fall frost , so roots bulk up in cool weather and turn sweeter after light frosts.
  • Carrots germinate best when soil is roughly 50–85°F , so avoid very cold or midsummer-hot soil if you can.

By climate / region style

Think in terms of how warm your winters are:

  • Cold/cool climates (short summers, regular frost):
    • Spring sowing: roughly early to mid‑spring , once soil is workable; often March–April depending on your zone.
* Fall sowing: mid‑ to late **summer** (July–August) to harvest in fall before the ground freezes.
  • Temperate areas:
    • Often sow from early spring through mid‑summer for continuous harvests, avoiding the very hottest weeks if summers are harsh.
* Many guides suggest sowing from about **March to July** in these conditions.
  • Mild/warm winters (many parts of the South, Mediterranean‑like climates):
    • Carrots shine as a cool‑season crop: sow in late winter to early spring , then again late summer to fall once heat breaks.
* In warm regions, fall is often the **best** time because cooler weather reduces bolting and improves flavor.

Simple rule of thumb

  • Aim to grow carrots through the coolest half of your growing season.
  • If you know your local frost dates, just remember:
    1. Spring crop: sow a little before last frost.
    2. Fall crop: sow about 10 weeks before first frost.

Forum‑style note and “latest talk”

Gardeners on blogs and forums in 2025–2026 keep repeating the same pattern: treat carrots as a cool‑season staple, stagger sowings every few weeks in spring and late summer, and let fall crops catch a light frost for extra sweetness.

TL;DR: Plant carrots when it’s cool – a few weeks before last spring frost, and again about 10 weeks before first fall frost, adjusting exact dates to your local climate.
