Hardneck garlic wins in New York, hands down. Duganski, German Red and Chesnok Red shrug off the freeze-thaw cycles that crack this state’s ground apart before spring ever settles in, while softnecks like Inchelium Red and Lorz Italian can still be grown here but need extra mulch to make up for winters they were never bred to handle. Cold isn’t actually the obstacle — New York’s chill lasts far longer than any clove needs to divide properly. Survival is the real dividing line between varieties.
The short answer for New York
For most of the state, hardneck garlic is the safer bet. Hardneck types such as Duganski, German Red and Chesnok Red are described in seed catalogs as more cold-tolerant than softnecks, and that matters in a climate where the ground freezes and thaws more than once before spring. Softneck varieties like Inchelium Red and Lorz Italian still grow well here, but they were bred for milder winters and need a heavier mulch to compensate.
New York’s cold season is not the limiting factor either way. NOAA’s climate data for the same New York City station used above shows the region running roughly 17.4 weeks with temperatures below 40°F each winter, well past the six to eight weeks garlic needs after planting to divide into individual cloves, according to the University of Georgia Extension (publication C854). That margin means every variety on this list will vernalize properly here. What separates them is winter survival, not whether the cold arrives.
The set-out window for every variety below, hardneck or softneck, works out to late October through early November once you count back from New York City’s first fall frost. That frost date is a midpoint, not a guarantee: in roughly one year out of two, the first freeze at 32°F arrives after November 27, and in the other half it arrives before November 14. Plan around the window, not a single day inside it.
Varieties by type
| Type | Varieties | Set-out window |
|---|---|---|
| Hardneck | Bavarian Purple, Blue Music, Chesnok Red, Duganski, Fall Festival, Georgian Crystal, Georgian Fire, German Red, German White, Ivan | Late October to early November |
| Softneck | Early Red Italian, Inchelium Red, Italian Late, Lorz Italian | Late October to early November |
Working it out for your own garden
The late-October-to-early-November window above is anchored on one station, NOAA’s Central Park data, which represents New York City weather, not the whole state. If you garden anywhere else, the same arithmetic still works. You just need your own first-frost figure to start from.
Redoing the math for your own county
Start with your area’s average first fall frost date, available from Cornell Cooperative Extension’s county offices or from NOAA’s climate normals for the station nearest you. Growers around New York City count back roughly two to four weeks from the November 14 to 27 window to land on a late-October to early-November planting date, timed so the cloves root before the ground locks up hard but don’t push top growth before winter. Apply the same two-to-four-week rule to your own frost figure and you’ll land on your own planting window.
Three things move that starting frost date, and each is worth checking before you commit to a planting day. Elevation is the biggest one: gardens several hundred feet higher than the valley floor nearby will frost earlier in fall and stay frosty later in spring. Closeness to a large lake works the opposite way in autumn, since the water holds heat and delays the first freeze near the shoreline, though it can also load the ground with insulating lake-effect snow once winter sets in. Coastal exposure along the Atlantic acts much the same way: nearby water moderates the air and pushes the first frost later than it falls even a short distance inland.
None of these adjustments needs to be precise to the day. Garlic tolerates being planted across a two-to-three week span without much difference in the following summer’s bulb size, so use your best estimate of the local frost date, subtract a few weeks, and get the cloves in the ground before you’re gambling on soil that’s already begun to freeze.

What changes across New York
The frost figures above describe New York City, and NOAA notes that Central Park is a dense urban site: the pavement and buildings hold heat, so the Adirondacks and the rest of upstate New York frost far earlier in fall and stay frosty far later in spring than the city does. A grower near Lake Placid or Old Forge should expect to plant weeks ahead of a grower in Queens, not on the same late-October to early-November calendar.
Regions that run colder or milder
Western New York, especially the ground near Lake Erie and Lake Ontario, sits inside the region’s lake-effect snowbelt. The lakes delay the first freeze near the shoreline in autumn by holding onto summer heat, but once winter arrives they also dump heavy, wet snow that can bury a garlic bed under a foot or more of natural insulation, which is no bad thing for a dormant clove. Gardens a few miles inland from the lake, out of that moderating and insulating effect, see a harder and more variable freeze-thaw cycle over winter.
The Hudson Valley runs a middle course between the city and the Adirondacks, with frost timing that shifts with elevation along the river corridor, earlier on the valley’s higher ground and later close to the water. Long Island and the rest of the New York City metro area stay the mildest part of the state through fall, benefiting from the same moderating water and urban heat that shapes the Central Park normals themselves.
None of this changes which varieties will grow here. It changes when you plant them and how much mulch goes down before the ground freezes for good, since a bed that ends up buried under snow naturally needs less added protection than one that sits exposed to open winter wind.
The mistakes this climate punishes
The first mistake is planting too late. Because the first fall frost is a midpoint, with the freeze landing after November 27 in roughly half of all years around New York City, it’s tempting to wait. But garlic needs a few weeks of root growth before the ground locks up, and a clove planted right at the frost window instead of ahead of it goes into winter with no root system to anchor it. The result is a clove that heaves partway out of the soil during the freeze-thaw cycles that follow, and a plant that either dies or comes up weak in spring.
The second is planting too shallow, or skipping mulch on the assumption that a hardneck variety’s cold tolerance means it doesn’t need protection. Cold tolerance in the plant itself doesn’t stop frost heave, which is a physical problem: repeated freezing and thawing of the top few inches of soil pushes shallow cloves upward regardless of variety. A few inches of straw mulch put down after planting, before the ground freezes solid, does more to prevent this than choosing one cultivar over another.
Seed stock and disease risk
The third mistake is buying seed garlic without asking where it was grown or whether it has been checked for disease. According to the UC IPM Pest Management Guidelines for onion and garlic (UC ANR Publication 3453), white rot, caused by the fungus Sclerotium cepivorum, becomes active across a 50 to 75°F range, and New York’s average air temperature, measured at one reference station rather than statewide, falls inside that range in five months of the growing season, including September and October, right when fall-planted cloves go into the ground. Those are published soil-temperature thresholds compared here against air temperature, and a monthly average inside the range does not mean every day that month favors the disease. It also does not mean the reverse: a month outside the range does not make white rot, or any other soil-borne pathogen, impossible in a New York garden. Infected seed stock carries the fungus wherever it’s planted.
- Ask the supplier where the seed garlic was grown, not just the variety name.
- Skip replanting cloves from any bed that showed stunted or yellowing plants last summer.
- Get cloves in the ground with enough time to root before the soil freezes solid.
- Mulch every variety, hardneck included, once the cloves are planted.
Checking this against your county
Every figure above is measured at or near New York City, and the state extension system publishes county-level detail that citywide averages can’t capture. Cornell Cooperative Extension maintains local offices with frost data and planting guidance specific to each county, from Suffolk out to Erie and Franklin. Before you lock in a planting date for a garden outside the city, check with the Cornell Cooperative Extension office for your county, and weigh it against the basics in Growing Garlic in New York if you haven’t yet settled on depth and spacing for the variety you’ve chosen.
Common questions
Can I plant garlic in New York in spring instead of fall?
You can, but expect smaller bulbs. Garlic planted in spring skips most of the cold period it needs to divide into cloves, and the six-to-eight-week chilling requirement cited by the University of Georgia Extension is hard to meet once the ground has already warmed. Fall planting, timed to New York’s frost window, is what lets the bulb size up properly by the following summer.
Does hardneck garlic actually survive New York winters better than softneck?
As a type, yes. Hardneck varieties are consistently described in seed catalogs as more cold-hardy than softnecks, which is why growers in colder parts of the state lean toward names like Duganski or German White. Softnecks like Lorz Italian still produce a full crop here with a thicker mulch layer, they just carry less margin for a hard winter with poor snow cover.
What happens if I miss the late-October window?
Get the cloves in as soon as you can, even into November, rather than holding them until spring. A late-planted clove that gets even a couple of weeks of root growth before the ground freezes does better than one held back for a spring planting, though you should mulch heavily to make up for the lost rooting time.
Do I need different varieties for Long Island than for upstate?
Not necessarily different varieties, but different timing and mulch depth. All fourteen varieties named here are suited to New York’s overall cold season, but a garden in the Adirondacks or the Lake Ontario snowbelt should plant earlier than the late-October to early-November window calculated for the New York City area, since local frost arrives well ahead of the city’s.
