When to plant carrot by zone

Last updated · Sources: NOAA NCEI 1991–2020 Climate Normals frost dates; timing rules described in our methodology

Daucus carota is a cool-season crop that is hardy to frost. Rule of thumb: direct sow from 3 weeks before to 2 weeks after the last frost; for a fall crop, sow or plant 10–12 weeks before the first fall frost.

Carrot planting dates by zone

Each row uses the median 30%-risk frost dates of the major cities in that zone; rows marked * have no major city and use the median of NOAA stations in that zone instead. Frost dates vary a lot within a zone, so use your city page for local dates. In frost-free climates: Sep 1 – Feb 28.

Carrot planting questions

When can I plant carrot outside?

Sow seed directly from 3 weeks before to 2 weeks after the last frost, once the soil reaches about 45°F (7.2°C). Examples: zone 5a (median last frost May 4): Apr 13 – May 18; zone 6b (median last frost Apr 26): Apr 5 – May 10; zone 8a (median last frost Apr 1): Mar 11 – Apr 15.

Can I grow carrot as a fall crop?

Yes. Sow or plant 10–12 weeks before your first fall frost. For a first frost around Oct 15, that is Jul 23 – Aug 6. Add about two weeks to the days to maturity for slower fall growth — see fall planting.

How long does carrot take to grow?

60–80 days from sowing. As a hardy cool-season crop it grows best in cool weather, so spring plantings should mature before summer heat, and fall plantings need about two extra weeks because days are shorter.

What soil temperature does carrot need?

At least 45°F (7.2°C) at planting depth. Cold soil slows germination more than a short delay in planting does, so in a cold spring it pays to wait a week past the usual date. As a hardy crop, carrot tolerates light frost.

How far apart should I plant carrot?

Recommended in-row spacing: 2–3 in. Keep the seedbed moist until sprouts appear — it can take 2–3 weeks.

When do you plant carrot where frost is rare?

In frost-free climates, plant carrot Sep 1 – Feb 28, timing growth for the mildest months. This applies to cities such as Los Angeles, CA, San Diego, CA, San Francisco, CA.
