Vermont Planting Guide: What to Grow and When

Vermont’s growing season is short—most gardeners get somewhere between 120 and 150 frost-free days, depending on whether they’re gardening in the Champlain Valley or in the Northeast Kingdom at 1,500 feet. That constraint sounds limiting until you taste a carrot pulled from cold Vermont soil in October, or bite into an apple variety that needs exactly this kind of prolonged chill to develop full flavor. The short season does not reduce what Vermont gardeners can grow. It sharpens the selection.

This guide covers everything you need to plan a Vermont garden from scratch: the state’s USDA hardiness zones, average last and first frost dates by region, a month-by-month planting calendar, and a curated list of vegetables, fruits, and flowers that perform reliably in Vermont conditions. Sources draw on University of Vermont Extension and USDA climate data throughout.

Vermont USDA Hardiness Zones

Vermont spans USDA hardiness zones 3b through 5b, a range that covers most of what a gardener needs to know about winter survival for perennials, trees, and shrubs. The zones do not directly control when you plant—that is governed by frost dates—but they determine which perennial plants overwinter reliably and which are marginal.

The Champlain Valley, which runs along Lake Champlain from the Canadian border to the southern tip of the lake, is the mildest part of the state. Burlington sits in zone 5a, and the moderating effect of the lake keeps temperatures slightly warmer than the surrounding uplands in both spring and fall. The Green Mountains divide the state into east and west climatic zones: the western slopes drain into warmer valleys, while the eastern slopes face the Connecticut River Valley with colder air drainage. The Northeast Kingdom—Orleans, Essex, and Caledonia counties in the far northeast—is the coldest region, with zone 3b readings in the highest elevations.

For gardeners, the practical takeaway is this: most of Vermont falls in zones 4a through 5a. Zone 4 plants—including hundreds of perennial flowers, fruiting shrubs, and cold-hardy vegetables—will overwinter reliably across the vast majority of the state. Zone 5 additions become available as you move toward Burlington and the Champlain Valley. As warming climate patterns continue shifting hardiness zones northward, Vermont gardeners are gaining access to plants previously considered marginal.

Vermont Frost Dates: Last Spring Frost and First Fall Frost

Frost dates are the critical numbers for every planting decision. The dates below come from NOAA climate normals and University of Vermont Extension records, representing the 50% probability date—meaning there’s a 50% chance of frost on or before (for fall) or after (for spring) these dates. For a 90% frost-free guarantee, add 10–14 days to the spring date and subtract 10–14 days from the fall date.

Note that elevation matters enormously in Vermont. A garden at 1,000 feet in the same county as a valley garden may see its last frost two or three weeks later. If you’re gardening at higher elevations, treat your microclimate as a zone colder than the regional average and plan accordingly. Row covers and cold frames can extend your effective season by two to four weeks at either end.

Vermont Planting Calendar: Month by Month

The calendar below is calibrated for central Vermont (Montpelier/Burlington corridor). Gardeners in the Champlain Valley can shift warm-season transplant dates approximately one week earlier; Northeast Kingdom gardeners should shift them one to two weeks later.

For a deeper look at planning your entire calendar year—including flower sequences, bulb timing, and indoor sowing schedules for all US regions—see the year-round planting guide.

Cool-Season Vegetables: Vermont’s Strongest Category

Cool-season vegetables are the backbone of a Vermont garden. These are crops that germinate in cold soil, grow best when daytime temperatures stay in the 50–70°F range, and tolerate light frost without damage. Vermont’s long springs and autumns—cooler and wetter than most of the country—are ideal conditions for these plants.

Peas are the traditional first crop. Plant them as soon as soil can be worked, typically late April in the Champlain Valley, early to mid-May in colder regions. Bush peas (such as ‘Maestro’ and ‘Lincoln’) suit Vermont’s shorter season better than tall climbing varieties, which need more days to full production. Peas tolerate light frost and actually taste sweeter when night temperatures drop into the 40s.

Spinach is one of Vermont’s most reliable crops. Sow outdoors from late April onward; resow every two to three weeks through June for a continuous harvest. A fall succession planted in mid-August will produce right up to hard frost and, under a low tunnel, often into November. Vermont Extension recommends ‘Bloomsdale Long Standing’ and ‘Tyee’ for their resistance to bolting in the warm spells that can interrupt spring harvests.

Lettuce follows the same pattern but bolts faster in summer heat. Focus succession plantings in spring and again in August for fall. Loose-leaf varieties (‘Salad Bowl’, ‘Red Sails’) tolerate Vermont’s variable spring temperatures better than butterhead types, which need more consistent warmth to form tight heads.

Kale may be the single most productive vegetable for a Vermont garden. It tolerates hard frosts, harvests continuously from midsummer through November (and under cover through December), and improves in flavor after the first frost converts starches to sugars. Varieties like ‘Lacinato’ (dinosaur kale) and ‘Red Russian’ are well-suited to Vermont conditions. Direct sow in May or transplant from starts started indoors in April.

Brassicas—broccoli, cabbage, and cauliflower—need to be started indoors in early April and transplanted out in early to mid-May, when soil temperatures have reached 45°F. Vermont’s cool summers favor broccoli especially: the heads develop slowly and with more uniform density than in warmer climates. Cauliflower is more temperature-sensitive and benefits from consistent irrigation during head development. For both, ‘Arcadia’ broccoli and ‘Snowball Y Improved’ cauliflower are reliable Vermont performers according to UVM Extension trial data.

Warm-Season Crops: Timing Is Everything

Warm-season vegetables—tomatoes, peppers, cucumbers, squash, beans, and corn—need frost-free conditions and soil temperatures above 60°F to perform. In Vermont, that window opens between early May in the warmest Champlain Valley locations and late May in the Northeast Kingdom. Every week of season extension matters.

Tomatoes are the crop Vermont gardeners invest the most effort in, and for good reason: a well-chosen variety transplanted after last frost, given a warm, sheltered location, and supported with a black plastic mulch to boost soil temperature will produce abundantly through September. Choose varieties with days-to-maturity under 75 days for most of Vermont. ‘Siletz’ (70 days), ‘Stupice’ (52 days), and ‘Sungold’ cherry tomato (57 days) are frequently recommended by Vermont gardeners and UVM Extension for their cold-soil tolerance and reliable ripening in short seasons. Avoid large beefsteak varieties with 85+ days to maturity unless you’re gardening in the warmest Champlain Valley microclimate.

Peppers and eggplant need the warmest spots in a Vermont garden. Start them indoors by mid-March, give them supplemental heat during germination (soil temperature 80–85°F for germination), and do not transplant until soil has warmed above 65°F—typically late May to early June across most of Vermont. Black plastic mulch is strongly recommended. Choose early-maturing pepper varieties: ‘Gypsy’ (65 days), ‘Ace’ (70 days), and ‘Carmen’ (72 days) all perform well in Vermont trials. Eggplant varieties with days-to-maturity under 65 are safest.

Cucumbers do well in Vermont when started indoors two to three weeks before last frost (late April) and transplanted once soil is warm. ‘Marketmore 76’ and ‘Straight Eight’ are dependable standard cucumbers; ‘Picklebush’ suits gardeners with limited space. Direct sowing after last frost is possible but gives up three to four weeks of production compared to transplants—a significant loss in a short season.

Winter squash is Vermont’s great harvest-season triumph. Varieties like ‘Butternut’, ‘Delicata’, ‘Red Kuri’, and ‘Jarrahdale’ store for months after harvest and provide produce well into winter. Start indoors in late April, transplant in late May, and harvest before hard frost in September or October. Squash vines benefit from ample space and consistent moisture during fruit development.

Beans are direct-sown after last frost. Bush varieties like ‘Provider’ and ‘Contender’ are faster than pole beans and better for Vermont’s short season. Make two or three succession plantings through mid-June to extend harvest.

Sweet corn is marginal in the Northeast Kingdom but fully viable in the Champlain Valley and southern Vermont. Choose varieties under 75 days to maturity. ‘Bodacious’ (75 days) and ‘Kandy Korn EH’ (80 days) are popular choices; ‘Precocious’ (65 days) is the best option for coldest locations.

Top Plants for Vermont Gardens

Root Vegetables: The Vermont Winter Cellar

Root vegetables are where Vermont gardening shows its historical depth. Before refrigeration, Vermont farmsteads depended on root cellars stocked with carrots, beets, turnips, parsnips, and celeriac to carry families through winter. That tradition aligns perfectly with what Vermont’s climate grows best.

Carrots in Vermont benefit from the cool soil temperatures that slow their growth just enough to concentrate sugars. Varieties with short to medium roots (Danvers, Chantenay types) work better than long Imperator varieties in the stony, glacially-deposited soils common across the state. Sow from mid-May through late June; thin to 2 inches apart. Carrots left in the ground past first frost and harvested in late October develop exceptional sweetness.

Beets are one of the most forgiving Vermont crops. Direct sow from May through July, thin to 3–4 inches, and expect harvest in 55–70 days. ‘Detroit Dark Red’ and ‘Chioggia’ (with its striking red-and-white ringed interior) both perform reliably. Beet greens from thinning are edible and provide early-season salad material while the roots are still developing.

Parsnips need Vermont’s long, cold autumn to fully develop their flavor. Sow in late May or early June—they need a full growing season—and leave them in the ground through multiple frosts before harvest. A parsnip dug in November after several hard frosts is a completely different flavor experience from one harvested in August. ‘Hollow Crown’ and ‘Harris Model’ are the standard Vermont choices.

Celeriac is an underused Vermont vegetable that deserves more attention. Start indoors in February (it needs 100–110 days), transplant in late May, keep consistently moist, and harvest large, knobby roots from September onward. The flavor is celery-rich without the stringiness; roots store well through winter. UVM Extension includes celeriac in its recommended vegetable list for Vermont gardeners specifically because of its reliable performance in cold summers.

Garlic is planted in fall, not spring, which makes it unique in the Vermont garden calendar. Plant cloves in September to mid-October—after the first frost has cooled soil but before hard freeze locks it—and harvest in late July the following year. Vermont’s cold winters provide the vernalization period garlic needs. Both hardneck varieties (‘Rocambole’, ‘Purple Stripe’, ‘Porcelain’) and softneck types grow well; hardnecks are generally preferred in Vermont because they produce scapes in early summer (a bonus harvest) and have better flavor complexity in cold climates.

Growing Fruit in Vermont

Vermont’s climate restricts some fruit crops but produces exceptional flavor in others. The cold winters provide the chilling hours that many tree fruits require; the relatively short summers concentrate sugars before harvest.

Apples are Vermont’s signature fruit, and for good reason: the Champlain Valley and southern Vermont have supported commercial apple production for over two centuries. For home gardeners, disease-resistant varieties require far less spray program than traditional varieties: ‘Liberty’, ‘Freedom’, ‘Enterprise’, and ‘Honeycrisp’ (zone 4 hardy) all perform well. Plant two varieties for cross-pollination. Dwarf and semi-dwarf rootstocks suit most home gardens and begin bearing in 3–5 years.

Blueberries thrive in Vermont’s naturally acidic soils but require attention to pH: they need a soil pH of 4.5–5.0 for optimal production. Native highbush blueberries (Vaccinium corymbosum) are zone 4 hardy and produce abundantly in Vermont. ‘Patriot’, ‘Northblue’, and ‘Blueray’ are recommended by UVM Extension for the state. Plant at least two varieties for cross-pollination and maximum fruit set.

Strawberries are the most accessible Vermont fruit for new gardeners. June-bearing varieties (‘Honeoye’, ‘Jewel’) produce a concentrated harvest in late June to early July; everbearing types (‘Seascape’, ‘Albion’) produce two smaller flushes. Plant in spring, mulch heavily over winter with straw, and remove runners to maintain bed productivity. Most Vermont strawberry beds remain productive for 3–4 years before replanting.

Raspberries are well-suited to Vermont and require minimal inputs once established. Fall-bearing varieties (‘Heritage’, ‘Autumn Britten’) that produce on first-year canes simplify management: mow all canes to the ground in late fall, and the new growth produces fruit the following August through October. Summer-bearing varieties (‘Boyne’, ‘Killarney’) are more cold-hardy and produce in July but require more careful cane management.

Currants and gooseberries are cold-hardy to zone 3 and are underutilized in Vermont gardens. Black currants make exceptional jam and juice; red and white currants are milder. Both tolerate partial shade better than most fruiting plants, making them useful in gardens with limited full-sun space. ‘Ben Sarek’ black currant and ‘Consort’ are zone 4-hardy and productive in Vermont conditions.

Companion Planting for Vermont Gardens

Companion planting—pairing plants that benefit each other through pest deterrence, nitrogen fixation, or microclimate improvement—is especially valuable in Vermont’s short season, where a pest outbreak or disease problem has fewer weeks to recover from. Several classic combinations work particularly well in Vermont conditions.

The Three Sisters planting (corn, beans, and squash) has Indigenous origins and performs beautifully in Vermont’s humid summers. Corn provides a trellis for climbing beans; beans fix nitrogen that benefits both corn and squash; squash’s large leaves shade the soil, suppressing weeds and retaining moisture. Plant after last frost when soil is fully warm.

Basil and tomatoes are a classic pairing for good reason: basil is said to deter aphids and tomato hornworm when planted close to tomato plants. In Vermont, the combination also makes practical sense because both need the same warm, sheltered microclimate—a south-facing bed against a fence or building wall—and can share that prime real estate.

Marigolds planted throughout a Vermont vegetable garden deter nematodes and aphids and attract beneficial insects. French marigolds (Tagetes patula) rather than African marigolds are better suited to Vermont’s shorter season and will bloom reliably from transplant through October.

For a complete breakdown of which vegetables help each other—and which actively compete—see the companion planting guide.

Perennial Flowers for Vermont Gardens

Vermont’s cold winters and reliable snowfall create ideal overwintering conditions for many perennial flowers. The following are consistently reliable across most of the state (zone 4 and colder).

Coneflowers (Echinacea purpurea) are native prairie plants that thrive in Vermont’s full-sun gardens. They tolerate both drought and Vermont’s summer humidity, bloom from July through September, and provide seed heads that attract goldfinches through winter. Zone 3 hardy. ‘Magnus’ and ‘Kim’s Knee High’ are reliable varieties.

Black-eyed Susans (Rudbeckia fulgida) bloom heavily from late July through October and are among the most deer-resistant perennials for Vermont gardens—a practical consideration in a state with a high deer population. Zone 3 hardy; self-seeds freely.

Hostas are the workhorse of Vermont shade gardens. Hardy to zone 3, they emerge reliably every spring and provide structural foliage interest from May through October. Slug damage is the main concern in Vermont’s wet summers; apply iron phosphate-based slug bait in May before damage begins.

Daylilies (Hemerocallis) are zone 3 hardy, bloom from June through August depending on variety, and require essentially no maintenance once established. ‘Stella de Oro’ and ‘Happy Returns’ rebloom reliably in Vermont’s short seasons. Avoid spreading varieties in natural areas; many daylilies escape cultivation and are invasive in Vermont’s roadsides and fields.

Astilbe performs exceptionally well in Vermont’s partial shade with consistent moisture. Bloom times range from late June through August depending on variety; plume colors include white, pink, red, and purple. Zone 4 hardy across most of the state.

Siberian iris (Iris sibirica) is one of Vermont’s most reliable flowering perennials. Zone 3 hardy, tolerant of both wet and dry conditions, and producing elegant blooms in June. Unlike bearded iris, Siberian iris is rarely troubled by the iris borer that affects other iris types. Varieties include ‘Caesars Brother’ (deep purple) and ‘White Swirl’.

Extending Vermont’s Growing Season

The 120–150 day frost-free window defines Vermont gardening, but it is not a hard limit. Season extension tools can add four to eight weeks of productive growing at either end of the season, making a meaningful difference in what you can grow and harvest.

Row covers are the most versatile tool. Lightweight floating row cover (Agribon-15 or equivalent) provides frost protection to about 28°F—enough to protect transplants during late cold snaps and extend fall harvests by several weeks. Heavier row cover (Agribon-30 or 50) provides protection to around 24°F and can be used over cold frames for overwintering spinach and kale.

Cold frames essentially add a full zone of warmth. A cold frame positioned on a south-facing slope in Vermont can start seeds four to six weeks before outdoor planting dates and continue producing salad greens until December. Use double-wall polycarbonate panels rather than single-pane glass for better insulation in Vermont’s cold winters.

Black plastic mulch is critical for warm-season crops in Vermont. Soil temperature under black plastic can run 8–10°F warmer than uncovered soil, which can be the difference between tomatoes that ripen fully and tomatoes left green on the vine at first frost. Lay plastic at least two weeks before transplanting to allow soil to preheat.

Wall-O-Waters and other season extenders allow Vermont gardeners to transplant tomatoes three to four weeks before last frost, gaining enough additional season to fully ripen even mid-season varieties in all but the coldest locations. These teepee-style water-filled sleeves protect plants to 16°F and have become standard practice among serious Vermont tomato growers.

Frequently Asked Questions

What growing zone is Vermont?
Vermont spans USDA hardiness zones 3b through 5b. Most of the state falls in zones 4a through 5a. The Champlain Valley (including Burlington) is the warmest region at zone 5a; the Northeast Kingdom and high elevations are the coldest at zones 3b–4a. For perennial plant selection, find your specific zip code in the USDA Plant Hardiness Zone Map.

When is the last frost in Vermont?
Last frost dates in Vermont range from late April in the warmest Champlain Valley locations to late May in the Northeast Kingdom and at high elevations. Burlington averages last frost around May 7; Montpelier around May 14; Newport in the Northeast Kingdom around May 24. Add 10–14 days for a 90% frost-free safety margin before planting frost-sensitive crops.

What vegetables grow best in Vermont?
Vermont excels at cool-season vegetables: kale, spinach, Swiss chard, broccoli, cabbage, peas, beets, carrots, and parsnips all perform extremely well. For warm-season crops, select early-maturing varieties (under 75 days to maturity) and use black plastic mulch and row covers to maximize the season. Root vegetables stored in a cold cellar provide produce through winter.

Can you grow tomatoes in Vermont?
Yes. Tomatoes grow reliably in Vermont with appropriate variety selection and season extension techniques. Choose varieties with 75 days or fewer to maturity—’Stupice’ (52 days), ‘Siletz’ (70 days), and ‘Sungold’ cherry (57 days) are Vermont favorites. Transplant after last frost, use black plastic mulch, and position in the warmest, most sheltered spot in your garden. In the Northeast Kingdom and at high elevations, Wall-O-Waters and row covers are essential for reliable production.

When should I plant garlic in Vermont?
Plant garlic in Vermont between mid-September and mid-October, after the first light frost has cooled soil but before the ground freezes hard. Hardneck varieties (Rocambole, Porcelain, Purple Stripe) are preferred in Vermont for their cold hardiness, complex flavor, and bonus scape harvest the following June. Mulch with straw immediately after planting to protect cloves through the winter. Harvest the following July when the lower leaves begin to brown.

What fruit trees grow in Vermont?
Apples are Vermont’s signature tree fruit and grow exceptionally well across the state. Disease-resistant varieties like ‘Liberty’, ‘Freedom’, and ‘Honeycrisp’ reduce spray requirements. Pears (especially Asian pears and European varieties on quince rootstock) are also reliable. Stone fruits—peaches, cherries, plums—are more marginal; hardy varieties like ‘Reliance’ peach (zone 4) and ‘Northstar’ cherry succeed in protected Champlain Valley locations but are risky in zones 4a and colder.

How do I deal with Vermont’s short growing season?
Focus on three strategies: choose varieties with short days-to-maturity for all warm-season crops, use season extension tools (row covers, cold frames, black plastic mulch, Wall-O-Waters) at both ends of the season, and fill the bulk of your garden with cool-season crops that thrive in Vermont’s natural climate rather than fighting it. A garden heavy with kale, root vegetables, broccoli, peas, and garlic—with a focused plot of properly supported tomatoes, peppers, and squash—will outperform a garden designed for a longer-season climate.
