What can you plant now, and will it finish in time? This Canada vegetable planting calendar is organised by season length rather than by province — Vancouver and Calgary are two months apart. Find your band from your frost-free days, then see what to sow, plant out and harvest each month, and which crops still have time to mature.

October
Clear, store and protect. The last roots come up after the first hard frost has sweetened them, and every empty bed gets covered before the snow.
Timings below assume a zone 3 to 6 season — the one most Canadian gardeners actually have. Coastal British Columbia runs weeks ahead and is called out where it matters.
Sow now
- Cover crops (zone 6)
- Cold-frame salads
- Microgreens indoors
- Nothing outdoors in zones 3–4
Plant now
- Garlic
- Bare-root fruit (zone 6)
- Rhubarb crowns
- Mulch the beds
Harvest now
- Parsnips (after frost)
- Brussels sprouts
- Kale
- Leeks & cabbage

Starting seed indoors
In a season of 90 to 130 frost-free days, starting seed indoors is not a refinement — it is the only way a tomato or a pepper reaches a harvest at all. A Prairie gardener who direct-sows a tomato in May is growing a plant that will be killed by frost while still setting its first fruit.
Count backwards from your own last spring frost, not from a calendar month. Everything in this table is expressed that way.
| Crop group | Start indoors | Move outdoors | Note |
|---|---|---|---|
| Onions, leeks, shallots | 10–12 weeks before last frost | 2–4 weeks before last frost | Slow from seed and tolerant of a long indoor period. Prairie gardeners often sow these in February. |
| Peppers and eggplant | 8–10 weeks before | 2 weeks after last frost | Need nights holding above 10 °C before they go out, whatever the frost date says. In short-season areas they are worth a cloche as well. |
| Celery and celeriac | 10–12 weeks before | 1–2 weeks before last frost | Slow, cold-tolerant once hardened, and rarely worth direct sowing anywhere in Canada. |
| Tomatoes | 6–8 weeks before | 1–2 weeks after last frost | Sown earlier than this they become root-bound and stall after transplanting — a real risk when eagerness meets a late May frost date. |
| Brassicas | 4–6 weeks before | 2–4 weeks before last frost | Tolerate frost and can go out ahead of the frost date, which is how short-season gardeners buy back three weeks. |
| Cucurbits | 3–4 weeks before | After last frost, soil above 15 °C | Resent root disturbance — sow into individual modules and move them on quickly. Never bare-root them. |
The common short-season mistake is sowing indoors too early rather than too late. A tomato held eight weeks past its transplant date in a small pot loses more to check and root binding than it gained from the early start.
Read soil temperature, not the calendar
Air temperature is what you feel; soil temperature is what the seed responds to. In a Canadian spring the gap between them is wide and it lasts for weeks — frozen ground releases its cold slowly, and a run of warm afternoons in early May can leave the soil at 6 °C while the air reads 20 °C. That gap is why so many Prairie bean sowings rot rather than germinate.
Measure at seed depth: push a soil thermometer 5–10 cm into the bed and read it in the early morning, when soil is at its coldest. Afternoon readings flatter the surface and mislead. Take readings on three consecutive mornings before deciding — one warm morning is weather, not a trend.
| Crop group | Minimum | Ideal range | What it means in practice |
|---|---|---|---|
| Peas, spinach, lettuce | 4–5 °C | 7–21 °C | Slow but safe at the minimum. These are the crops that let a Canadian season start in April rather than late May. |
| Carrots, beets, radish, turnip | 7 °C | 7–29 °C | Carrot seed is slow to start — 10–21 days at the low end, so patience here is not a failed sowing. |
| Beans, sweet corn | 10 °C | 21–29 °C | Below 10 °C the seed rots instead of germinating. The single most common late-May failure in Canada. |
| Tomatoes, peppers, eggplant | 15 °C | 21–29 °C | Transplanted, not sown outdoors. Nights must also hold above roughly 10 °C. |
| Squash, cucumbers, melons | 15–16 °C | 21–35 °C | The warmest requirement of any common vegetable, and the strongest case for black plastic on the Prairies. |
Find your own frost dates
Every date on this page is relative to two numbers that belong to your garden, not to your province: your average last spring frost and your average first fall frost. Everything else is arithmetic from those two. Look them up in the Environment and Climate Change Canada Canadian Climate Normals for the station nearest you, and treat them as averages with real year-to-year spread — most Canadian growers add one to two weeks of buffer before setting out anything frost-tender.
Canadian hardiness zones are more useful here than American ones, and it is worth knowing why. The Agriculture and Agri-Food Canada zone formula — maintained by the Canadian Forest Service and updated in 2025 — is built from several climate variables rather than one, and the length of the frost-free period is explicitly among them, alongside the coldest month’s minimum, summer maximum temperature, June-to-November rainfall, winter severity, snow depth and wind gust. A USDA zone describes winter cold alone. A Canadian zone already carries some information about season length.
It still will not give you a date. Use the zone to find your station, then use the station’s normals for the two frost dates, then adjust for your own site. Cold air pools in hollows and drains off slopes, so a low-lying garden can run two weeks behind one a kilometre away on a rise. Large water bodies delay both frosts, which is why the Okanagan, the Niagara peninsula and the shores of the Great Lakes behave a full band warmer than the land around them. Elevation costs you roughly a week of season for every 100 m of gain. One season of your own written records beats any published average.
Will it finish? The arithmetic that matters most here
In a long season you can be casual about days to maturity. In Canada you cannot. The question is never what you would like to grow — it is what can still finish before the first fall frost.
Take the crop’s days to maturity from the seed packet, add two to three weeks, then count forward from your realistic planting-out date. If that lands after your average first fall frost, the crop will not finish, and no amount of watering changes it. The two- to three-week padding is not pessimism: catalogue figures assume ideal conditions and midsummer light, and growth slows sharply as days shorten in late August.
Canada gets one genuine advantage back. At Prairie and northern latitudes midsummer days are very long — Edmonton sees more than seventeen hours of daylight in late June — and that extra light partly offsets the shorter calendar. It helps leafy and root crops most. It does not rescue a crop that needs sustained warm nights, which is why melons and long-season peppers stay difficult north of the mild band however long the days get.
When the arithmetic fails, the answer is a faster crop rather than a later date:
| Crop | Typical days to maturity | Fits a window of |
|---|---|---|
| Radish | 25–30 days | Almost any gap, including early September in the medium band |
| Salad leaves and rocket | 30–40 days | A late-August sowing in the long and medium bands |
| Spinach | 40–50 days | An August sowing, and it overwinters under cover in the long band |
| Bush beans | 55–60 days | A late-June or early-July sowing where the season allows |
| Beetroot and early carrots | 55–70 days | A July sowing in the long and medium bands |
Frost tolerance buys real time at the end of the season, and this is where Canadian gardens quietly outperform their frost-free-day count. Kale, leeks, parsnips, Brussels sprouts and carrots are not merely frost-tolerant — they improve after frost, as stored starches convert to sugars. Counting those crops as finishing at first frost understates them by weeks. In much of the country parsnips and leeks are best left in the ground and lifted as needed.
What season extension actually buys you
Season extension is optional in a long season and close to essential in a short one. These are the methods that repay the effort, with the gains that research and extension services actually report rather than the gains catalogues promise.
| Method | Typical gain | How it works, and what it costs you |
|---|---|---|
| Choosing an earlier cultivar | 1–3 weeks | Free, and the most overlooked option in Canada. A cultivar bred for 65 days instead of 85 removes the risk entirely at no cost and no labour. Look for cultivars selected by Prairie or northern breeding programmes. |
| Floating row cover | 2–4 weeks at each end | Adds roughly 1–2 °C of frost protection and excludes flea beetles and root maggot flies at the same time — the cheapest intervention with the largest effect. Must be lifted or vented for insect-pollinated crops once they flower. |
| Black plastic mulch | 1–2 weeks earlier planting | Raises soil temperature several degrees; cole crops under it have been harvested seven to ten days earlier. Most valuable on the Prairies for cucurbits and corn, which are limited by soil warmth rather than air. Soil under plastic gets no rain, so it must be watered deliberately. |
| Clear plastic mulch | 2–3 weeks earlier planting | Warms soil harder than black — measured 4–6 °C above bare soil — but does nothing for weeds, which grow happily beneath it. Best used briefly to pre-warm a bed, then removed or replaced. |
| Mulch plus row cover together | 2–3 weeks, with a real yield effect | The combination is worth more than either alone: trials have started zucchini harvest ten to fourteen days earlier, with large increases in cucumber yield. |
| Low tunnels | 4–6 weeks at each end | Row cover or poly over hoops. Adds roughly 2–3 °C and is enough to carry hardy greens well past first frost in the medium band. |
| Cold frame or hotbed | 6–8 weeks at each end | Effectively shifts the bed one hardiness zone warmer, and is the traditional Canadian answer for hardening off. Needs venting on sunny days or it cooks the contents by mid-morning. |
| Greenhouse or polytunnel | 8+ weeks, and reliable warm-season crops | The only method that makes long-season peppers, melons and reliable tomatoes realistic in the short band. Also the only one with a real capital cost. |
Two cautions that catch people out. Anything under plastic needs watering by hand, because rain no longer reaches the root zone. And anything under a sealed cover on a sunny day will overheat within an hour or two — row covers and frames need managing, not just installing.
Used together, these methods can turn a 100-day Prairie season into something closer to 140 usable days. That is the difference between a tomato crop that ripens and one that gets picked green in September.
What this page can’t do for you
A calendar tells you what is possible. It doesn’t tell you what you decided.
Everything above is timing. What it cannot hold is your garden: which bed each crop is going into this year, which family was there last year, what you actually sowed and when, what germinated, and what you want to do differently next season. In a hundred-day season those are the decisions that separate a full harvest from a half one, and they are exactly the things people try to keep in their heads.
The Canada Vegetable Garden Planner is the paper system for that — short-season timing pages worked from your own frost dates, bed layouts, a four-year rotation planner, a seed inventory, a sowing log and a harvest tracker. Print it once, use it all season, print it fresh next January.

Frequently Asked Questions
How do I find my frost dates in Canada?
Check Agriculture and Agri-Food Canada's plant hardiness data for your location. As a guide, last spring frost is around 28 March in Vancouver, 20 April to 10 May in Toronto, 3 May in Montreal, 7 May in Edmonton and 23 May in Calgary.
How many frost-free days does Canada have?
It ranges from about 90 days in the far North and at elevation to 222 days on Vancouver Island. Most of Central Canada and the Maritimes fall between 130 and 170 days.
What soil temperature do I need before sowing in Canada?
About 4-5°C for peas and spinach, 7°C for carrots and beets, 10°C for beans, and 15-16°C for squash, cucumbers and corn. Cold spring soil is the most common cause of failed Canadian sowings.
How do I extend a short Canadian season?
Black plastic mulch to warm soil before planting, floating row cover for two to four extra weeks at each end, low tunnels and cold frames for hardy crops, and short-season cultivars, which cost nothing extra.
