Regional guide · hardiness Zone 5
The heart of Canadian and northern US gardening.
Zone 5 includes Ottawa, Montréal, Sherbrooke, Kingston and the Maritimes, plus Vermont, coastal Maine, the upper Midwest and Denver’s Front Range. Winters are cold and snowy, summers hot and humid (or hot and dry on the plains), and the five-month season supports almost any temperate crop. It is the reference zone for most seed-catalogue advice.
Winter low
−29 to −23°C
−20 to −10°F
Frost-free days
140–165
Typical frost window
Roughly early-to-mid May to early-to-mid October.

Gardening in Zone 5
Everything from asparagus to zucchini. The limiting factors are usually spring soil temperature, midsummer humidity (disease) and, on the plains, water. Fall gardening is under-used and rewarding here.
Vegetables that thrive
- Tomatoes of every type
- Peppers and eggplant
- Sweet corn
- Cucumbers, melons and squash
- Beans, peas and edamame
- Garlic and onions
- Brassicas, roots and greens spring and fall
- Sweet potatoes in warm sites
Fruit
- Apples and pears
- Plums and sour cherries
- Peaches in sheltered sites
- Grapes (hybrid and some vinifera)
- Raspberries, blackberries and blueberries
- Strawberries
- Kiwi (hardy Actinidia arguta)
- Hazelnuts
Reliable perennials & shrubs
- Peony, iris, daylily, hosta
- Coneflower, phlox and salvia
- Hydrangea (paniculata and arborescens)
- Roses (most shrub types)
- Lavender in well-drained soil
- Japanese maple in sheltered spots
Zone tips
- Direct-sow cool crops in mid-April; transplant tomatoes around the Victoria Day / Memorial Day weekend.
- Sow a second round of carrots, beets, kale and lettuce in late July for a fall harvest that outlasts the first frost.
- Plant garlic mid-October; harvest early-to-mid July.
- Mulch heavily in summer to hold moisture and suppress disease splash.
Fishing in Zone 5
Great variety: bass and walleye in the big lakes and rivers, pike and musky in the weeds, trout in the cold streams and Great Lakes tributaries, and Atlantic salmon and striped bass in the Maritime rivers.
Signature species
- Smallmouth and largemouth bass
- Walleye
- Northern pike and muskellunge
- Brook, brown and rainbow trout
- Lake trout and landlocked salmon
- Yellow perch, crappie and sunfish
- Steelhead and salmon (Great Lakes tributaries)
- Striped bass and Atlantic salmon (Maritimes)
Seasons, limits and licences vary by province and state; every local guide links to the right regulator.
Foraging in Zone 5
The richest foraging in the north: ramps and fiddleheads in spring, a big berry summer, then apples, nuts and the full fall mushroom flush in the hardwood forests.
What to look for
- Ramps / wild leeks
- Fiddleheads
- Morels
- Wild strawberries, raspberries, blackberries and blueberries
- Elderflowers and elderberries
- Chanterelles, hen of the woods, chicken of the woods, giant puffballs
- Wild apples, black walnuts, hickory nuts and butternuts
- Staghorn sumac and rose hips
Never eat anything you cannot identify with certainty. Confirm with a regional field guide or local expert.
