How to Grow Beets in Canada
How to grow beets in Canada starts with a question most guides skip: whether the crop fits your season at all. Beets need 50-60 days to maturity, so compare that against your frost-free days before anything else. Direct sow 2-4 weeks before the last spring frost and again in late summer for a fall crop. Give them full sun / part shade and space them 8-10 cm (3-4 in) apart.
Do beets fit your Canadian season?
Subtract days to maturity from your frost-free days. If the answer is not comfortably positive, the crop will not finish — no amount of good technique fixes an arithmetic problem. Beets need around 60 days from sowing or transplanting.
| Season band | Frost-free days | Days to maturity | Does it fit? |
|---|---|---|---|
|
Long season Zones 7-9 |
150-222 frost-free days | 50-60 days to maturity | Comfortable fit — room for a slow start. |
|
Medium season Zones 4-6 |
130-170 frost-free days | 50-60 days to maturity | Comfortable fit — room for a slow start. |
|
Short season Zones 2-3 |
90-130 frost-free days | 50-60 days to maturity | Comfortable fit — room for a slow start. |
When to plant beets in Canada
Timing runs from your local last spring frost: roughly 28 March in Vancouver, around 20 April to 10 May in Toronto, 3 May in Montreal, 7 May in Edmonton and 23 May in Calgary. Direct sow 2-4 weeks before the last spring frost and again in late summer for a fall crop.
Season extension for a short Canadian season
- Black plastic mulch laid two to three weeks before planting lifts soil temperature by several degrees — often the difference between a crop and a failure on the Prairies.
- Floating row cover adds roughly two to four weeks at each end of the season and keeps early pests off at the same time.
- Low tunnels and cold frames let hardy crops carry on well past the first frost, and let hardy sowings start earlier.
- Short-season cultivars are the cheapest form of season extension. Choosing one that matures two weeks earlier costs nothing and removes the risk entirely.
Soil and site
Loose, stone-free soil, pH 6.0-7.5. Reliable and frost tolerant.
Watering
Even moisture — irregular watering produces tough, woody roots.
Spacing and layout
Space beets 8-10 cm (3-4 in) apart. Crowding is the most common cause of disappointing yields — plants compete for light and water, and poor airflow between them raises disease pressure sharply.
Companion planting
Onion, garlic, brassicas; avoid pole beans nearby.
Common problems
Leaf miner tunnels through leaves but rarely threatens the root itself.
Cold spring soil is behind more Canadian failures than any pest. Seed sown below its germination minimum rots rather than sprouts, and a warm-season transplant set out into cold ground is stunted for the rest of the season even if it survives. Waiting a week is almost always cheaper than re-sowing.

Frequently Asked Questions
Can I grow beets in Canada?
Beets need around 60 days, so compare that against your frost-free days — roughly 90-130 on the Prairies, 130-170 through Central Canada and the Maritimes, and 150-222 on the coast.
When should I plant beets in Canada?
Direct sow 2-4 weeks before the last spring frost and again in late summer for a fall crop. Work from your local last frost — around 28 March in Vancouver, 20 April to 10 May in Toronto, 3 May in Montreal and 23 May in Calgary.
How far apart should beets be planted?
Space them 8-10 cm (3-4 in) apart.
What usually goes wrong with beets in Canada?
Leaf miner tunnels through leaves but rarely threatens the root itself. Cold spring soil is the other common cause of failure — sowing before the soil has reached the crop's germination minimum causes seed to rot rather than sprout.
