How to Grow Carrots Canada
On this page
In Canada, carrots go in the ground mid April to late April, and are ready to harvest 65–112 days after planting.
Timing is the decision that matters most in Canada: there are 6 separate regional sowing windows, ranging from early March in Pacific Coastal Mild to late May in Far North & Alpine.
The short answer
- Plant
- Mid April to late April
- Ready in
- 65–112 days
- Site
- 6+ hours of sun, soil pH 6–6.5
- Biggest risk
- Alternaria leaf blight

| Central Continental derived | mid April to late April |
| Prairies & Short-Season Continental derived | early May to mid May |

Rows marked derived are interpolated between regions our sources do state, because no source we consulted gives a figure for that region specifically. They are deliberately wider to reflect that uncertainty.
Central Continental - detail & sources
DERIVED from this region's own frost normal, not quoted for the region. Sow 1-2 weeks before the last expected spring frost date. Mature carrots can stay in the ground while soil remains unfrozen at -1°C or warmer, and a light frost sweetens them. Applied to a mean last frost of 30 April (NOAA NCEI 1991-2020 for the USA; Environment and Climate Change Canada normals for Canada), that gives 16 April to 23 April. Your own local frost date is what matters — a region spans a range, and this figure comes from one representative station within it.

Soil & Growing Conditions
Growth Stages
| Stage | BBCH | Notes |
|---|---|---|
| Sowing & germination | 0 | Sow direct where plants are to grow — carrots resent transplanting. Make a shallow drill about 1cm (½in) deep, water the base, and sow seed as thinly as possible, spacing rows 15–30cm (6–12in) apart. The main sowing window is April to early July, with early crops from February–March under cloches or fleece; sowing after mid-May helps dodge the first carrot fly generation. Germination is slow (often 2–3 weeks) and needs soil above about 7°C, ideally around 13°C — keep the drill moist until seedlings emerge. |
| Thinning & leaf growth | 3 | Once seedlings are large enough to handle, thin to 5–7.5cm (2–3in) apart — overcrowding produces small, distorted roots. Thin on a still, damp evening and remove the thinnings, as crushed foliage releases the scent that attracts carrot fly. Keep beds weed-free, since carrots are poor competitors, and water only in prolonged dry spells (a good soak every fortnight); young plants are otherwise fairly drought tolerant. |
| Root swelling | 7 | The taproot swells and colours up. Aim for steady, even soil moisture: irregular watering or heavy rain after drought makes roots split, while excess moisture near harvest can cause cracking. Avoid high-nitrogen feeds, which encourage forking and leafy tops at the expense of the root. Keep insect-proof mesh in place against carrot fly, whose larvae tunnel into the swelling roots. |
| Maturity & harvest | 8 | Lift carrots as soon as they are large enough to use — earlies from around 65 days, maincrop from about 10–16 weeks (65–112 days). Ease off watering as harvest approaches. Store lifted roots with the tops removed in boxes of moist sand, or leave maincrop in the ground under a straw or cardboard mulch, lifting before the soil becomes waterlogged. Cold storage near 0.6°C with high humidity keeps topped carrots for four to six months. |

Soil Preparation
Carrots need deep, loose, stone-free soil -- heavy clay or stony ground is the leading cause of forked, misshapen roots. On heavy soil, grow shorter varieties such as Paris Market or Chantenay, or use raised beds or large containers filled with a sandy compost mix. Don't add fresh manure before sowing, as it also causes forking; well-rotted compost worked in the previous autumn is a better choice.
Recommended Varieties
- Nantes 2 — cylindrical, sweet and reliable; a classic UK allotment carrot that suits most soils.
- Paris Market — round, stumpy roots ideal for shallow or stony soil; ready quickly from successional sowings.
- Flyaway — bred for carrot fly resistance, with good flavour and reliable yields; a sensible choice for exposed plots.
- Chantenay Red Cored — short, stout roots that perform well in heavier soils; sweet, tender and stores well.
Plan your Carrots planting
When to sow and plant Carrots depends on your own frost dates. Check the Canada vegetable planting calendar, or the month-by-month guides that cover Carrots: April, May, June, July, August, October, November.

Sow 1-2 weeks before the last expected spring frost, about 1 cm deep and 2 cm apart, thinning to about 8 cm. Germination quickest at 20°C taking 7 days, against up to 17 days at 10°C, and needs consistent moisture from sowing to emergence. 65-80 days by cultivar. Mature carrots can stay in the ground while soil remains unfrozen at -1°C or warmer, and a light frost sweetens them and improves storage. Store at 0°C and 95-100% humidity. Leafhoppers are the commonest carrot pest.

Frequently Asked Questions
When should I sow carrots in Canada?
In Pacific Coastal Mild, from early March. In Far North & Alpine, wait until late May. Treat these as a guide rather than a fixed date — the governing rule is to sow only once frost risk has passed and temperatures are reliably warm enough.
When do I sow carrots?
Sow early March to late May, at around 13°C for germination.
How long do carrots take to grow?
Typically 65–112 days, depending on cultivar and growing conditions.
What soil pH do carrots need?
A pH of about 6–6.5. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect carrots?
Our data links 2 diseases and 10 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
Short-season growing is arithmetic before it is technique: days to maturity against frost-free days decides what will finish at all. The Canada Garden Planner does that subtraction for your region before you sow.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against Canadian hardiness-zone and frost-date data, with provincial agriculture and university extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
