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.

Turn January's jobs into a written plan. The Canada Vegetable Garden Planner (printable PDF) has frost-date planning pages, bed layouts, crop rotation, a sowing log and a harvest tracker — 70 printable pages.

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.
