Northwest Territories in USDA Zones 1–2
Northwest Territories spans Zones 1–2. Variety lists below are organized by zone — start with your zone for the most accurate recommendations.
Growing Brassicas in Northwest Territories
Zone 3's harsh winters and short summers create unique challenges for brassica growing, but these cool-season crops are actually perfect partners for your northern climate. With temperatures that can dip to -40°F in winter and a growing season that rarely exceeds 120 days, you need varieties that mature quickly and can handle temperature swings. The good news? Most brassicas prefer cooler weather and actually develop better flavor after light frosts, making them ideal for zones where tomatoes struggle.
When selecting brassicas for Zone 3, prioritize varieties with short maturity dates (60-80 days for most crops), excellent cold tolerance, and resistance to bolting during unexpected warm spells. Fast-maturing varieties like Early Jersey Wakefield Cabbage and De Cicco Broccoli are lifesavers when you're racing against September's first frost. Meanwhile, ultra-hardy options like Red Russian Kale and Purple Top Turnip can survive well into October, extending your harvest season when every day counts.

Zone 3 Growing Tips for Northwest Territories
Start your brassica seeds indoors 6-8 weeks before your last frost date, which means getting seeds in the ground by mid-March for Zone 3. This indoor head start is crucial since direct seeding often fails in short-season climates. Transplant seedlings outdoors 2-3 weeks before your last frost (late April to early May), as most brassicas can handle light frosts down to 28°F once established. Use row covers or cold frames to protect young plants during those inevitable late spring cold snaps that can set back growth by weeks.
For fall crops, timing is even more critical in Zone 3. Count backward from your first frost date (typically September 15) and add 2-3 weeks for slower fall growth, then start seeds accordingly. Brussels sprouts and late cabbage varieties need to be started by early June, while quick crops like arugula and radishes can be direct seeded as late as early August. Consider succession planting every 2-3 weeks for continuous harvests, and always have row covers ready – they can extend your season by 3-4 weeks on both ends.
