Growing in Zone 1
Growing food in Zone 1 is extremely challenging because of the very short, cold growing season and long, harsh winters. Focus on the cold-hardiest crops, season extenders like greenhouses and low tunnels, and starting seeds indoors very early so you can take full advantage of every frost-free day.
Vegetables
Fruits & Berries
Herbs
Kale, spinach, radishes, leaf lettuce, peas, turnips, beets, green onions (with protection), baby carrots in containers, mache, arugula in cold frames, Asian greens (tatsoi, mizuna) under cover, microgreens grown indoors, sprouting seeds (lentils, mung beans) on the counter
Rhubarb, hardy apples (on very cold‑hardy rootstock), currants, gooseberries, haskap berries, hardy raspberries, hardy bush cherries (like Nanking or Carmine Jewel), lingonberries in protected spots, dwarf berries in containers moved to shelter
Chives, parsley, mint (in pots), dill, thyme (in a protected spot), oregano in containers, sorrel, lovage (with winter protection), garlic chives in a cold frame, potted rosemary overwintered indoors
How to Grow in Zone 1
Successful gardening in Zone 1 requires meticulous planning and resourcefulness. Since the growing season may be as short as 50 days, it is vital to utilize techniques such as raised beds, which warm up faster in the spring, and heavy mulching to protect roots from late frosts. Indoor seed starting is a necessity, giving crops a head start before they are moved to sheltered outdoor environments like polytunnels or cloches. Focus on short-season varieties specifically bred for northern climates to ensure a harvest before the first hard freeze returns.
