Best Peas to Grow in New Brunswick

Start your first Zone 5 pea planting 2-4 weeks before your last frost date – typically mid to late March when soil can be worked. Peas germinate slowly in cold soil, so don't rush if temperatures are still dropping below 40°F regularly. Plant successive crops every 2 weeks through early May, switching to heat-tolerant varieties like Wando or Lincoln for plantings after April 15th. For fall crops, count backwards 10-12 weeks from your October 5th first frost date, making late July the ideal time for fall sowings.

Zone 5's unpredictable spring weather – from late snowstorms to sudden warm spells – requires flexible season extension strategies. Row covers are essential for protecting early plantings from unexpected freezes and can advance your harvest by 1-2 weeks. In years with late springs, consider starting peas indoors in biodegradable pots 3-4 weeks before transplanting, though direct seeding generally produces stronger plants.

The biggest Zone 5 challenge is managing the transition from cool spring to warm summer. Once daytime temperatures consistently hit 75°F, pea production drops significantly. Combat this by providing afternoon shade for late plantings, maintaining consistent soil moisture, and choosing varieties specifically bred for heat tolerance. Mulching becomes critical by late May to keep roots cool and extend your harvest window.
