What to Plant in February in Canada: Sowing by Hardiness Zone

In Canada, what you can plant in February is determined entirely by your regional climate zone, ranging from indoor seed propagation to early outdoor sowing under cover. While growers in the freezing interior must focus on starting slow-growing crops under grow lights, gardeners in mild coastal British Columbia can begin direct sowing hardy greens. Understanding these distinct regional timelines prevents wasted seed and ensures strong spring transplants.

The Canadian Plant Hardiness Zone system

Before selecting seeds, growers must identify their position on the Canadian Plant Hardiness Zone map. Unlike the USDA scale, which relies solely on minimum winter temperatures, the Canadian system incorporates multiple climate variables: minimum winter temperatures, frost-free period length, summer rainfall, maximum temperatures, wind speed, and snow cover. This creates a highly accurate representation of regional growing conditions, though it means a Canadian zone designation does not perfectly match its USDA equivalent.

Zones 2 to 3 (Prairies, northern Ontario/Quebec, the North)

In these northern and interior regions, outdoor soils remain frozen deep underground, and winter temperatures regularly drop below minus thirty degrees Celsius. Planting in February is strictly an indoor pursuit, focused on crops that require an exceptionally long head start before the short summer window. For detailed strategies on managing these short seasons, consult our guide on zone 2-4 gardening in Canada.

1. Slow-growing perennial vegetables

Certain perennial crops require a long period of root development before they can be planted out in late spring. February is the ideal time to sow seeds for perennial crops such as globe artichokes and wild leeks indoors. Starting them now gives the young plants sufficient time to establish a strong root system before transplanting in late May or early June.

2. Onions and leeks from seed

Onions and leeks grown from seed take up to twenty-four weeks to reach maturity. Sow seeds in flat trays filled with a free-draining seed-starting mix. Keep the soil at twenty-one degrees Celsius until germination occurs, then move the seedlings to a cool room with intense supplemental light to prevent them from becoming spindly.

Zones 4 to 5 (Interior Ontario and Quebec, southern Manitoba)

These regions experience severe winters, but the spring transition occurs slightly earlier than in the far north. February is a transitional month where indoor sowing begins in earnest, particularly during the final two weeks of the month. To coordinate your indoor schedule, refer to our comprehensive guide on when to start seeds indoors in Canada.

1. Early brassicas

Crops such as heading cabbage, broccoli, and kohlrabi can be started indoors in late February. These cool-season crops can tolerate light frosts once acclimatized, allowing them to be transplanted outdoors under protection in late April. Sow seeds in modular trays to minimize root disturbance during transplanting.

2. Celery and celeriac

Celery and celeriac seeds are tiny and require light to germinate. Press the seeds gently into the surface of moist compost without covering them. Place the trays under grow lights in a warm room, maintaining a temperature of twenty to twenty-two degrees Celsius. These crops grow very slowly in their early stages and benefit from a February start.

Zones 6 to 7 (Southern Ontario, the Maritimes, Fraser Valley)

In these moderate zones, winter is beginning to lose its grip, though frost remains a constant presence. Gardeners can start a wider variety of crops indoors and begin preparing outdoor beds under protective structures.

1. Peppers and eggplants

While tomatoes should wait until March, peppers and eggplants require a longer germination and growing period. Start these heat-loving crops in late February using a heated germination mat to maintain a soil temperature of twenty-four degrees Celsius. Supplemental lighting is necessary, as natural February daylight is insufficient for healthy growth.

2. Salad greens under cover

If you have a cold frame or greenhouse, you can sow cold-hardy salad greens such as spinach, winter lettuce, and corn salad. These crops will germinate slowly in the cool soil but will provide an exceptionally early spring harvest. For methods on protecting these early plantings, read about season extension in Canada.

Zone 8 (Coastal British Columbia)

Coastal British Columbia enjoys the mildest winter climate in Canada. Here, February brings genuine opportunities for outdoor planting, provided the soil is workable and not completely waterlogged. To plan your coastal garden calendar, check our guide on when to plant vegetables in BC.

1. Direct sowing hardy greens

In well-drained beds, you can direct-sow spinach, kale, mustard greens, and arugula. These seeds can germinate in soil temperatures as low as five degrees Celsius. Covering the seeded rows with horticultural fleece or a low tunnel protects the emerging seedlings from heavy coastal rains and occasional overnight frosts.

2. Broad beans and early peas

Broad beans and round-seeded early peas can be sown directly into the garden in mid-to-late February. These varieties are highly resistant to rot in cold, damp soil. Plant them in a sunny, sheltered spot, and ensure the soil is free of standing water to prevent the seeds from decaying before they sprout.

Essential February gardening jobs in Canada

Successful spring gardening relies heavily on the preparation completed during the final weeks of winter.

1. Testing seed viability

Before ordering new stock, test the germination rate of older seeds left over from previous seasons. Place ten seeds between damp paper towels, seal them in a plastic bag, and keep them in a warm room. Check the seeds after ten days: if fewer than seven seeds have germinated, discard the packet or sow the seeds much more thickly than usual.

2. Setting up and sanitizing equipment

Clean all seed trays, pots, and propagation domes with a mild soap solution to eliminate overwintering pathogens. Test your grow lights and replace any bulbs that have lost intensity. Ensure your seed-starting compost is stored indoors for at least twenty-four hours before use so that it is warm when seeds are sown.

3. Tapping maple trees

For homesteaders in eastern Canada and parts of the West, late February marks the beginning of the maple sugaring season. As daytime temperatures rise above freezing and nighttime temperatures drop below zero, sap begins to flow. Learn the exact process in our guide on how to tap a maple tree.

4. Monitoring winter mulch and structures

Inspect outdoor beds to ensure winter mulch has not blown away, exposing perennial roots to freeze-thaw cycles. Brush heavy, wet snow off greenhouses, cold frames, and high tunnels to prevent structural damage.
