What to Plant in January Canada
On this page
What to plant in January in Canada depends entirely on your zone — this page answers it for every band. January is a planning month everywhere in Canada. Nothing goes in the ground. Use it to confirm your last frost date, count your frost-free days, and pick cultivars whose days to maturity actually fit your season.
January planting by region
| Band | Sow outdoors | Start indoors | Plant out | Harvest now |
|---|---|---|---|---|
|
Long season Zones 7-9 |
Nothing outdoors. | Onions and leeks late month. | Nothing. | Overwintered kale, leeks and hardy greens. |
|
Medium season Zones 4-6 |
Nothing. | Nothing yet — too early. | Nothing. | Stored roots, squash and onions. |
|
Short season Zones 2-3 |
Nothing. | Nothing. | Nothing. | Stored crops only. |
January garden jobs
- Look up your last spring frost and first fall frost date, then subtract to get your frost-free days.
- Choose cultivars by days to maturity against that number, not by picture.
- Order seed early — short-season cultivars are the first to sell out in Canada.
- Inventory and germination-test leftover seed.
- Sketch next season's rotation while last year is still fresh.
Common January mistakes
- Buying a 100-day tomato for a 100-day season, which leaves no margin at all.
- Using American catalogue dates without adjusting for a shorter Canadian season.
- Waiting until March to order, by which point short-season cultivars are gone.
- Planning by hardiness zone alone — zones describe winter cold, not season length.

Frequently Asked Questions
What should I do in the garden in January in Canada?
Plan. Confirm your frost dates, count your frost-free days, choose cultivars whose days to maturity fit that number, and order seed before short-season varieties sell out.
How many frost-free days does my region have?
Roughly 150-222 on the Pacific coast and in the southern Ontario lake belt, 130-170 through Central Canada and the Maritimes, and 90-130 across the Prairies and the North.
Is January too early to start seeds in Canada?
For almost everything, yes. Only onions and leeks on the coast justify a January start; anything else becomes leggy and root-bound long before it can go out.
