Best Vegetables to Grow in Vermont

Vermont's short, cool growing season is tailor-made for cool-season crops โ€” peas and kale thrive here like nowhere else in the Northeast. Focus on varieties with the shortest days to maturity and you can squeeze impressive harvests out of a 130-day window.

Cold climateUSDA zone 514 crops

Vermont gardeners work within one of the tightest growing windows in the continental U.S. Most of the state sits in USDA zone 5, with last spring frosts running from mid-May in the Champlain Valley to late May or early June in the Northeast Kingdom. First fall frosts arrive as early as mid-September in elevated areas, leaving many gardeners with 110 to 140 frost-free days โ€” and less in a bad year.

That constraint is actually an asset for cool-season vegetables. Crops that bolt, turn bitter, or succumb to disease in Virginia's humid summers grow slowly and sweetly through Vermont's mild July and August. The cold snaps that follow harvest improve the flavor of kale, carrots, and beets through starch-to-sugar conversion that warm climates can't replicate.

The strategic moves in Vermont are timing and variety selection. Start transplants indoors 6โ€“8 weeks before your last frost, choose the earliest-maturing varieties available, and plan for two seasons: a spring crop direct-sown as soon as soil is workable and a fall crop back-counted from your first expected frost date. Row cover, cold frames, and low tunnels can add four to six weeks on each end of the season.

Why each one works

01

Pea

Cool-season 55โ€“70 days

Peas germinate in cold soil as low as 40ยฐF and actually require cool weather to set pods properly, making them Vermont's quintessential spring crop. Direct sow as soon as the ground can be worked โ€” typically late April โ€” and you'll harvest before summer heat stalls production. Choose 'Sugar Ann' snap peas (52 days) or 'Maestro' (61 days) for reliable yields within the short window.

Broccoli

Cool-season 60โ€“90 days

Vermont's cool summers keep broccoli heads tight and reduce the bitterness that plagues the crop in heat; side-shoot production continues well into fall after the central head is cut. Start transplants indoors 6โ€“8 weeks before last frost for a spring crop, or direct-sow in early July for a fall harvest timed to light frost, which sweetens the heads. 'Belstar' and 'Arcadia' are proven performers in northern New England trials.

Cabbage

Cool-season 60โ€“100 days

Cabbage's wide maturity range lets Vermont gardeners plan strategically: early types like 'Earliana' (60 days) fit a direct spring planting, while storage types like 'Premium Late Flat Dutch' started indoors in April produce heads that keep through winter in a root cellar. It's one of the few crops that fills both a short-season fresh slot and Vermont's homesteading tradition of cold storage.

Cauliflower

Cool-season 60โ€“100 days

Cauliflower demands a sustained cool period without hard freezes to form a proper curd โ€” Vermont provides that window, but timing is critical. Target a fall rather than spring harvest: transplants set out in late June mature into the consistent cool of August and September, which produces tighter, whiter heads than a rushed spring crop. Tie outer leaves over the forming curd once it reaches golf-ball size to blanch it and protect against early frost damage.

Kale

Cool-season 50โ€“65 days

Kale is arguably Vermont's most reliable vegetable โ€” it tolerates hard frost, keeps producing through light snow, and improves dramatically in flavor after cold converts starches to sugars. Direct sow in early May or set transplants in midsummer for a crop that runs well into November; 'Winterbor' and 'Red Russian' both handle Vermont winters under row cover. A planting timed to mature in September and October yields some of the sweetest kale you'll taste anywhere.

Lettuce

Cool-season 30โ€“60 days

Lettuce's 30โ€“60 day maturity makes it easy to fit multiple successions into Vermont's schedule, and its preference for cool weather means peak quality during the seasons Vermont does best โ€” spring and fall. Succession-plant every two weeks from late April through mid-August to avoid bolt; loose-leaf types like 'Black Seeded Simpson' are more bolt-resistant than head types and can be harvested leaf by leaf to extend each planting. Row cover extends the season on both ends with minimal effort.

Spinach

Cool-season 35โ€“50 days

Spinach germinates in near-freezing soil and can be direct-sown as early as late March under row cover, making it one of the first crops in the ground each Vermont spring. It bolts as day length exceeds 14 hours, so harvest your spring planting by late June, then resow in August for a fall crop that lasts well into October. 'Tyee' and 'Melody' are slow-to-bolt hybrids that meaningfully extend the productive spring window.

Swiss chard

Cool-season 50โ€“60 days

Swiss chard occupies a useful niche in Vermont: nearly as cold-hardy as spinach but tolerant of Vermont's brief warm spells in July without bolting, it bridges the gap between spring and fall cool-season crops. Sow after last frost, harvest continuously through the season by taking outer leaves, and it will survive light frost into November โ€” extend it further with row cover. 'Bright Lights' handles Vermont's variable summer temperatures well and produces reliable yields from one planting.

Carrot

Cool-season 60โ€“80 days

Vermont's cool soil slows carrot growth and concentrates sugars in a way warm-climate production cannot match, but stony soils require deep amendment with compost to prevent forked roots. Sow in mid-May once soil clears 50ยฐF, then leave roots in the ground through September frosts, which triggers the best sweetness before final harvest. Shorter Chantenay types like 'Bolero' manage stony Vermont soils better than long Imperator types.

Beet

Cool-season 50โ€“70 days

Beets are among Vermont's most forgiving vegetables: they germinate in cool soil, tolerate frost at both ends of the season, and offer two harvests โ€” greens early and roots later โ€” which doubles the productivity of a short growing window. Direct sow from late April through mid-July in two or three successions; a final sowing in late July sizes up through September's cool nights and stores well through winter in a root cellar. 'Detroit Dark Red' and 'Chioggia' are consistently reliable in Vermont conditions.

Radish

Cool-season 25โ€“35 days

At 25โ€“35 days to maturity, radishes are the fastest payoff in Vermont's garden and an ideal succession crop to tuck between slower vegetables in the same bed. Direct sow as soon as soil is workable in April, harvest before heat triggers bolting, then skip midsummer and resow in August for a crisp fall crop. 'Watermelon' radishes sown in late July mature into large, mild roots by October โ€” a fall variety worth the patience.

Onion

Cool-season 90โ€“120 days

Onions push the limits of Vermont's growing window at 90โ€“120 days, making an indoor start in late January or February the only reliable path to full-sized bulbs. Use long-day varieties bred for latitudes above 42ยฐN โ€” 'Copra' and 'Patterson' are proven storage onions for the region; short-day varieties simply won't bulb under Vermont's day-length conditions. Transplants consistently out-perform sets for both yield and storage quality.

Garlic

Cool-season 240โ€“270 days

Garlic sidesteps Vermont's short-season problem entirely by using the dormant winter months as part of its growth cycle: plant in October, overwinter in the ground, harvest in July. Choose hardneck varieties โ€” Rocambole types like 'German Red' or Porcelain types like 'Music' โ€” which are bred for cold climates and deliver far superior flavor to softneck types. Mulch crowns heavily with straw after the ground freezes to prevent the freeze-thaw heaving that kills cloves over a Vermont winter.

Strawberry

Cool-season 90โ€“110 days

Strawberries are a natural fit for Vermont as cold-hardy perennials that return each year, and Vermont's cool summers prevent fruit from softening too fast at peak ripeness โ€” a real quality advantage over warmer regions. June-bearing varieties like 'Honeoye' and 'Jewel' are bred for northern climates and deliver concentrated harvests in late June and early July; everbearing 'Seascape' extends picking into fall. Mulch crowns with straw after the ground freezes to protect against the freeze-thaw heaving that is the primary cold-climate killer of established beds.

Frequently asked questions

When is the last frost date in Vermont, and how do I use it to plan planting?

Last frost dates range from around May 10 in the Champlain Valley to June 1 in the Northeast Kingdom โ€” use your specific zip code via NOAA climate normals rather than a statewide average. Count back 6โ€“8 weeks from your date for transplant starts indoors, and count forward from it for frost-sensitive direct sowings like beans and squash. For frost-tolerant crops like peas, spinach, and kale, ignore the last frost date and sow 4โ€“6 weeks earlier as soon as soil is workable.

How do I extend my Vermont growing season without a greenhouse?

Low tunnels with row cover fabric (Agribon-19 or -30) are the most cost-effective tool, adding 4โ€“6ยฐF of protection and pushing your effective frost dates by three to four weeks on each end. Cold frames built from old window sashes let you overwinter spinach and kale for very early spring harvest without any supplemental heat. In fall, simply leaving frost-hardy crops like kale, carrots, and beets in the ground through light frosts extends harvest weeks longer without any infrastructure at all.

What vegetables should I start indoors versus direct sow in Vermont?

Start indoors anything with a long maturity that can't be direct-sown early enough to finish before fall frost: broccoli, cabbage, cauliflower, onions, and strawberry transplants all need the head start. Direct sow crops that are frost-tolerant and fast enough to mature without it: peas, spinach, radishes, beets, carrots, and kale can all go straight in the ground in April. Starting root crops like carrots and beets indoors is counterproductive โ€” they resent transplanting and perform better direct-sown.

Which Vermont vegetables can I harvest after the first fall frost?

Kale, spinach, and Swiss chard survive multiple hard frosts and actually improve in sweetness afterward โ€” plan to harvest them well into October and November with row cover. Carrots and beets can stay in the ground through frosts and be dug as needed; a layer of straw mulch insulates the bed and extends in-ground storage into early winter. Garlic overwinters entirely in the ground with no special protection beyond a straw mulch layer, and is harvested the following July.
