Understanding growing seasons across U.S. states is key for chefs, farmers, and food enthusiasts. A growing season is the frost-free period when crops can thrive, and it varies significantly by region due to climate and geography. Here’s a quick breakdown:
- Northeast: Short seasons (90–210 days), influenced by frost and varying climates. Crops include root vegetables, apples, and berries.
- Southeast: Long seasons (229+ days), warm climate, and multiple harvests. Known for peanuts, citrus, and peaches.
- Midwest: Moderate seasons (170–210 days), fertile soils, but weather unpredictability. Dominates in corn, soybeans, and dairy.
- Southwest: Shorter, heat-driven seasons with drought challenges. Focus on citrus, grapes, and heat-resistant crops.
- West: Long growing periods (up to 365 days in parts of California). Diverse crops like avocados, leafy greens, and citrus.
- Pacific Northwest: Mild, wet climate with 150–238 frost-free days. Famous for apples, berries, and seafood.
Climate change is extending seasons in many areas, but unpredictable weather poses challenges. Local sourcing and understanding these regional nuances help chefs craft seasonal menus while supporting farmers and reducing food miles.
Top State for Each Crop Grown in U.S.
1. Northeast
The Northeast, which includes states like New York, Connecticut, Maine, Massachusetts, and New Hampshire, showcases a wide range of growing conditions. These differences play a big role in what ingredients are available to chefs throughout the year.
Average Growing Season Length
The length of the frost-free period varies significantly across the region. In northern Maine and mountain valleys of the White and Green Mountains, the growing season can be as short as 90 days. Meanwhile, southern Maine and western Massachusetts average around 140 frost-free days, interior Connecticut and Rhode Island reach about 160 days, and coastal Connecticut can see up to 210 days [2].
Start and End Dates
Climate trends have shifted the Northeast’s growing patterns. Over the past 30 years, the last spring frost has been occurring about a week earlier [4]. However, research shows that the growing season’s expansion is more influenced by a later arrival of the first autumn freeze than by the earlier spring thaw [6]. For example, in the Long Island Sound Study area, the average growing season has grown to 161 days over the last 50 years (1973–2024), a notable increase from the historical average of 126 days recorded between 1778 and 1866 [5].
Key Climatic Factors
Several climate elements impact the Northeast’s growing season beyond its length. Factors like temperature, frost frequency, precipitation, and daylight hours all play a role [1]. The region has become warmer and wetter in recent decades, particularly during late winter and spring [4]. While these changes can extend harvest periods, they also disrupt traditional planting and harvesting schedules. For example, Maine experiences a shorter and later growing season compared to its neighboring states [3].
Notable Crops
The Northeast’s varied growing season allows for a rich selection of crops that can enhance seasonal menus. The harvest kicks off in April with specialty items like fiddleheads and ramps, followed by fresh greens and herbs in May. By summer (June through August), the region offers a wide array of vegetables and fruits, including berries, stone fruits, and tomatoes. As the season transitions into fall (September through October), root vegetables and late-harvest crops like cranberries and fennel take center stage, providing chefs with plenty of options for autumn-inspired dishes.
2. Southeast
The Southeast stands out as one of the most fertile agricultural regions in the United States, providing chefs with nearly year-round access to fresh, locally grown ingredients. States like Florida, Georgia, Alabama, Mississippi, South Carolina, North Carolina, Tennessee, Kentucky, Virginia, and West Virginia each offer a variety of crops that shape the flavors of Southern cuisine. Let’s break down the growing season, climate, and key crops that make this region so agriculturally rich.
Average Growing Season Length
With one of the longest frost-free growing seasons in the country, the Southeast enjoys an average of 229 days without freezing temperatures. Since 1970, this period has expanded by 18 days – and in some places, like Tupelo and Myrtle Beach, it has grown by as much as 52 days. This extended season allows for multiple harvests each year [7].
Growing Season Characteristics
Thanks to its southern location and the warm ocean currents nearby, the Southeast experiences minimal freezing. This creates an extended growing period that supports robust agricultural production [8].
Key Climatic Factors
The Southeast’s climate is shaped by its southern latitude and proximity to the Atlantic Ocean and Gulf of Mexico. Average temperatures hover around 72°F, with rainfall ranging from 40–50 inches inland and over 60 inches along the Gulf Coast. However, recent years have seen more extreme weather patterns [8].
Interestingly, even a small rise in temperature can significantly impact crop yields. Research shows that a 1°C increase in maximum growing season temperatures could reduce corn yields by about 15% [9].
The region also faces a variety of extreme weather events, including heat waves, cold snaps, droughts, floods, blizzards, hurricanes, and tornadoes. Florida, for example, records more tornadoes per square mile than any state except Kansas [8]. These weather challenges directly influence the types of crops that thrive here.
Notable Crops
The Southeast’s long growing season and diverse climate allow for an impressive range of crops. Here’s a closer look at some of the region’s agricultural highlights:
- Florida: Citrus reigns supreme, with 382,803 acres dedicated to citrus fruits [11]. The state also leads in fresh tomato production, contributing 54% of national cash receipts, along with sweet corn (36%) and watermelon (32%) [12].
- Georgia: Known for poultry, peanuts, and pecans, Georgia produces 51% of the nation’s peanuts annually [10] [12].
- Alabama: Poultry, especially broilers, is the state’s top commodity, though cotton remains the most widely planted crop. Alabama is also the second-largest peanut producer in the U.S. [10] [12].
- North Carolina: This state ranks in the top five for tobacco, sweet potatoes, poultry and eggs, cucumbers, and bell peppers. In 2021, it accounted for 47% of the nation’s tobacco and 58% of its sweet potatoes [12].
- South Carolina: The state excels in broilers, turkeys, greenhouse nursery products, cotton, and corn. It’s also the second-largest peach producer in the country [10] [11].
"The Southeast remains a set of fairly distinct markets presenting different problems and opportunities for agricultural asset owners." – Peoples Company [12]
This incredible crop variety provides chefs with endless possibilities for creating seasonal, locally inspired dishes. From Florida’s tropical citrus fruits to North Carolina’s sweet potatoes and Georgia’s peanuts, the Southeast offers a wealth of ingredients that celebrate the region’s agricultural heritage.
3. Midwest
Known as America’s Breadbasket, the Midwest is a powerhouse for producing corn, soybeans, and dairy. However, its growing season is shorter compared to warmer regions, which presents unique challenges and opportunities for agriculture.
Average Growing Season Length
The Midwest’s growing season is gradually getting longer, though the changes vary by state. For instance, Iowa’s growing season now spans between 170 and 210 days, increasing by about 1 to 3 days per decade. This means the state has gained an additional 8 to 12 days compared to historical averages [13]. Similarly, Illinois has seen its growing season expand by 10 to 15 days over the past 50 to 60 years [13]. Iowa State Climatologist Justin Glisan highlights this trend:
"What we’ve seen is an expansion of the growing season across the Midwest and Iowa." [13]
Despite this lengthening, unpredictable year-to-year variations make planning a challenge for farmers.
Start and End Dates
Shifts in climate are altering when the growing season begins and ends. In Missouri, for example, the last spring freeze now occurs 3 to 6 days earlier, while the first autumn freeze arrives nearly a week later than in the past [13]. Generally, central and southern parts of the Midwest enjoy a growing season from April to October, while northern areas have a shorter window due to earlier frosts [18]. Looking ahead, projections suggest the frost-free period could extend by about 10 days early in this century and up to a month by its end [14]. These timing changes also affect crucial climatic factors that determine crop performance.
Key Climatic Factors
The Midwest’s fertile soil and abundant water resources have long supported its agricultural success, but climate change is adding new hurdles. Average temperatures in the region have risen by more than 1.5°F from 1900 to 2010 [16]. Increased spring rainfall can delay planting, increase erosion, and promote mold growth, while higher humidity extends dew periods that benefit pests [14]. Warmer winters allow more insects and crop diseases to survive, and hotter summers are expected to reduce yields by increasing evaporation and depleting soil moisture [14].
Extreme weather events further complicate farming. Over the past seven decades, 43% of spring floods have resulted in crop losses [15]. Steve Long, a plant biologist at the University of Illinois, reflects on the growing unpredictability:
"I think everybody’s been taken aback by the predictions that extreme events will become more common. But I think it’s happened at a scale that nobody quite expected." [15]
Notable Crops
Even with these challenges, the Midwest remains a vital agricultural hub, producing about 27% of the nation’s agricultural output. Corn and soybeans dominate, covering roughly 75% of the region’s arable land. The Midwest also supplies 15% of the country’s dairy products [17].
The region’s agricultural profile is diversifying, with specialty crops gaining momentum. In 2022, vegetables brought in $2.6 billion, wheat $2.1 billion, fruits and tree nuts $1.2 billion, berries $445.1 million, Christmas trees $81.2 million, and barley $34.5 million [19]. This shift is opening new opportunities for chefs to incorporate locally sourced ingredients like apples, grapes, cherries, cranberries, blueberries, and pumpkins into seasonal menus that celebrate the Midwest’s agricultural bounty.
4. Southwest
The Southwest is known for its intense heat, dry conditions, and shifting growing seasons, which create a mix of hurdles and possibilities for local food production.
Average Growing Season Length
In the Western U.S., the growing season has been getting longer, increasing by about 2.2 days per decade since 1895 – more than twice the rate of the East, which has seen nearly one day per decade of growth [1]. The region’s climate also stands out with an average high temperature of 66.6°F and a low of 37.0°F, compared to the national averages of 63°F and 41°F.
Key Climatic Factors
The Southwest is often referred to as a climate change hotspot due to its unique vulnerabilities. Studies predict that average annual temperatures in the region could rise by 4–10°F compared to 1960–1979 levels [22]. Low rainfall and high seasonal heat define its arid climate [21], and the area has endured some of the most persistent droughts on record since 1990 [21]. These changes are reshaping ecosystems; for instance, in the Santa Rosa Mountains, dominant plant species shifted upslope by around 65 meters between 1977 and 2007. Additionally, spring is arriving earlier, accompanied by increasingly unpredictable winter precipitation [22].
Notable Crops
Despite the challenges, the Southwest has embraced a three-season growing strategy to make the most of its conditions. This includes planting fast-growing cool-season crops in spring, heat-resistant vegetables during summer, and a variety of crops in fall. Livestock production also plays a major role in the region’s agricultural economy. Nearly 60 percent of Nevada’s land and over a third of land in New Mexico and Arizona is used for grazing [23]. Hay, in particular, dominates cropland use in the area.
The Southwest’s climate also supports a variety of specialty crops that thrive in hot, dry conditions, adding to its rich culinary landscape. Heat-adapted produce like citrus fruits (lemons and tangerines), cantaloupes, peanuts, and onions flourish here. Certain tree fruits, including specific varieties of apples, apricots, and peaches, as well as grape cultivars like Cardinal, Flame seedless, and Thompson seedless, have been cultivated to withstand the region’s intense summer heat.
This innovative three-season growing approach lays the groundwork for a deeper dive into the unique agricultural conditions of the West in the next section.

5. West
The West is experiencing notable changes in its growing season, creating exciting opportunities for chefs and food enthusiasts alike. These longer seasons mean greater access to a variety of locally grown ingredients over extended periods, reshaping how menus are planned and ingredients are sourced.
Average Growing Season Length
The growing season in the West has expanded significantly, with over two additional weeks of growing time since the early 20th century [1]. This shift, particularly noticeable since the 1970s, reflects a steady lengthening of the season, offering more opportunities for agricultural production [1].
However, the West’s vast and varied geography means growing seasons differ widely. For instance, in California, the high Sierra Nevada sees a growing season as short as 50 days, while the southern coast enjoys a year-round growing period of 365 days [24]. Coastal valleys and the Central Valley benefit from a freeze-free window of 225–300 days, ensuring nearly continuous access to fresh produce [25]. These differences are shaped by the region’s unique microclimates.
Key Climatic Factors
The West’s diverse landscape plays a major role in shaping its growing conditions. California, for example, experiences a wide range of climates influenced by latitude, elevation, and proximity to the Pacific Ocean [27]. Coastal areas enjoy the ocean’s moderating effects, leading to milder winters and cooler summers. In contrast, inland areas face more extreme temperature swings [27].
The Mediterranean climate of California’s coastal regions and Central Valley features warm, dry summers and cool, wet winters [27]. During summer, the semi-permanent Pacific high moves north, creating dry conditions, while winter storms bring rain to lower elevations and snow to the mountains [25]. Temperature extremes are striking, with recorded lows of –45°F and highs of 134°F [25]. Southern California showcases dramatic contrasts, where winter temperatures along the coast can be 4°F warmer than inland valleys, but summer differences can reach up to 23°F [27].
In states like Nevada and Utah, arid to semi-arid climates dominate, with elevation heavily influencing both temperature and precipitation [20]. This variety of climates not only determines the length of the growing season but also influences the types of crops that can thrive.
Notable Crops
Thanks to these extended and varied growing seasons, farmers in the West can cultivate an impressive range of crops and even achieve multiple harvests from the same land [1]. Along California’s coast, year-round conditions support the continuous production of leafy greens, herbs, and specialty vegetables. Meanwhile, the Central Valley’s extended freeze-free season allows for multiple plantings of fast-growing crops, boosting agricultural diversity.
"A plant’s performance is governed by the total climate: length of growing season, timing and amount of rainfall, winter lows, summer highs, wind, and humidity." – Sunset Plant Collection [26]
This understanding of climate has led to the identification of 15 distinct climate zones across the West. Each zone supports specific crops based on factors like growing season length, rainfall patterns, temperature extremes, and humidity levels [28].
For chefs, these evolving growing conditions mean a steady supply of fresh ingredients. Spring crops are arriving earlier, and fall harvests are lasting longer, giving culinary professionals more flexibility in crafting seasonal menus. In areas like Utah, chefs can refine their skills and adapt to these changes through hands-on training at institutions like Park City Culinary Institute.

Regional Growing Seasons and Their Impact
These differences in growing conditions demand localized culinary approaches. For instance, chefs in the West benefit from a gradually lengthening growing season – extended by an average of 2.2 days per decade since 1895 [1]. This gives states like California, Oregon, and Washington more time to source fresh, seasonal ingredients.
Seasonal cycles are crucial to ingredient availability, with over 70% of fresh produce sales tied to these patterns [36]. The Southeast’s long growing period allows for steady local sourcing, while in the Northeast, chefs often rely on preservation techniques and partnerships with producers of storage crops like root vegetables and apples.
However, climate challenges are changing the game. Severe weather events are disrupting supply chains nationwide [37]. In the Southeast, hurricanes can cause sudden shortages, while in the West, chefs face wildfire smoke and strict water usage regulations. These issues are not going unnoticed – 74% of consumers believe weather-related problems will have an even bigger impact on food availability in the future [37].
The Case for Local Sourcing
Transportation is a major contributor to food-related emissions, accounting for 20% of total food production emissions and 36% of emissions for fruits and vegetables [39]. Sourcing locally helps cut these numbers significantly. Plus, it offers fresher, more flavorful ingredients.
"Locally sourced ingredients reduce transport emissions vs foods that travel thousands of kilometers to reach our plates. Seasonal ingredients taste better, are less inexpensive, more nutritious, and help fight illnesses the new seasons might bring."
- Chef Pinky Maruping [39]
Nutritional value is another reason chefs prioritize local, seasonal produce. For example, broccoli harvested in the fall contains nearly twice the vitamin C of spring-grown varieties [38]. However, timing is everything – fruits and vegetables begin losing nutrients within 24 hours of harvest [39]. This forces chefs to carefully balance peak freshness with storage needs.
Building Resilient Supply Chains
With rising food prices, supply chain resilience is becoming more important than ever [37]. Around 75% of companies are now investing in stronger supply networks or adopting farming methods that can better withstand environmental challenges [37]. These efforts are reshaping ingredient availability and pricing across the country.
Chefs are also finding region-specific solutions. In the Pacific Northwest, year-round farmers’ markets help kitchens maintain seasonal menus. Meanwhile, in the Midwest, chefs excel at preserving and storing crops to make the most of short growing seasons.
