Introduction

September marks a vibrant transition in the United States, as the rich harvests of late summer converge with the earthy abundance of early fall. This is a pivotal month for seasonal eating, offering a diverse array of fruits and vegetables at their peak flavor and nutritional value. Choosing produce at its seasonal prime is the simplest way to ensure superior taste, maximize nutritional intake, and support local economies, all while minimizing your environmental footprint. This guide provides a comprehensive overview of what to look for and how to enjoy September’s bounty.

Why Eat In-Season in September?

Seasonal eating goes far beyond simple preference—it is a conscious choice with tangible benefits for your health, your wallet, and the planet.

  • Peak Flavor and Freshness: Produce harvested at its peak is at its most flavorful, aromatic, and juicy. Unlike off-season imports, which are often picked before they are fully ripe, in-season produce travels shorter distances from farm to table.
  • Nutritional Powerhouse: Fresh, local produce retains more vitamins, minerals, and phytonutrients than crops that have been stored or shipped over long distances. For example, September’s apples are bursting with vitamin C and soluble fiber, while ripe tomatoes are a superior source of antioxidant-rich lycopene.
  • Health and Wellness: Beyond foundational nutrients, many seasonal foods contain potent compounds linked to positive health outcomes. Lycopene, the phytonutrient responsible for the red color in tomatoes, is one of the most powerful dietary antioxidants. Research suggests that a high intake of tomatoes and tomato products may be associated with a reduced risk of certain cancers, including prostate cancer, and a decreased risk of cardiovascular disease. Similarly, apples are a rich source of flavonoids and pectin, which have been studied for their potential to lower cholesterol and support gut health.
  • Lower Cost and Reduced Environmental Impact: Abundant harvests lead to lower prices at farmers’ markets and supermarkets. This local-first approach also reduces your carbon footprint by minimizing the energy costs associated with long-distance transportation and cold storage.
  • Community and Sustainability: By purchasing in-season produce, you are directly supporting local farmers and the agricultural communities that sustain them. This practice fosters a deeper connection to the food you consume and strengthens the entire food system.

In-Depth: Key September Fruits and Vegetables

This section provides a closer look at some of the most popular produce items available this month, with details on selection, storage, and unique culinary uses.

Apples

Peak Availability: September–October

Nutrition: A medium apple contains approximately 4 grams of fiber, 9 mg of Vitamin C, and is rich in antioxidants like quercetin, catechin, and chlorogenic acid. The majority of an apple’s fiber and antioxidants are found in the skin, making it a good practice to eat the fruit whole.

Selection and Storage: Apple season is in full swing, especially for popular varieties like Honeycrisp, Gala, and McIntosh. Look for apples that are firm and free of soft spots. For baking, tart varieties like Granny Smith or Braeburn hold up well. For applesauce, sweeter, softer varieties are ideal. Apples can be stored in the crisper drawer of your refrigerator for several weeks.

Culinary Uses: Beyond simple snacking, September is the ideal time for apple pies, crisps, and sauces. Consider making a homemade applesauce or try savory applications like Roasted Pork Tenderloin with Apples or a Waldorf Salad.

Pears

Peak Availability: August–October

Nutrition: A medium pear contains about 6 grams of fiber, and is a good source of Vitamin C and K.

Selection and Storage: Pears, including popular varieties like Bartlett and Comice, are at their prime. Pears are unique because they taste best when picked mature but ripened off the tree. This ensures a silky, non-gritty texture. Unripe pears should be stored at room temperature, then refrigerated when they are perfectly soft at the neck. Use ripe pears within three to five days.

Culinary Uses: Poached pears with cardamom make a sophisticated dessert. They are also excellent sliced into salads with walnuts and blue cheese or baked into tarts.

Grapes

Peak Availability: August–October

Nutrition: Grapes are a good source of Vitamin K and copper, and are notable for their high content of antioxidants, especially resveratrol.

Selection and Storage: Locally harvested U.S. grapes, including Red Globe and Concord, are at their juiciest and most aromatic in September. When buying, look for grapes on a green stem, as a brown stem indicates the grapes are old.

Culinary Uses: While a perfect snack on their own, grapes also add a touch of sweetness to savory dishes. Try them roasted alongside meats or vegetables or make small-batch grape juice or jelly.

Sweet Corn

Peak Availability: July–September

Nutrition: Sweet corn is full of fiber and is a good source of B and C vitamins.

Selection and Storage: September marks the end of peak sweet corn season in most regions. Select corn with bright green husks and plump, firm kernels. It is best eaten as soon as possible after purchasing, as its sugars quickly convert to starch after being picked.

Culinary Uses: Grilled on the cob, sweet corn is a delicious side dish. It also makes a fantastic addition to soups, salads, and salsas.

Leafy Greens (Kale, Spinach, Swiss Chard)

Peak Availability: Kale (Sep–Feb), Spinach (Apr–Sep), Swiss Chard (Jun–Oct)

Nutrition: These greens are packed with vitamins A, C, and K, as well as iron and calcium.

Selection and Storage: Cooler nights in September boost the quality and sweetness of greens. Look for bright, crisp leaves free of wilting. Store greens in a plastic bag in the refrigerator crisper drawer to maintain freshness.

Culinary Uses: Baby kale and spinach are excellent raw in salads or smoothies, while mature kale holds up well when sautéed or added to soups. The entire beet plant is edible, and beet greens can be prepared just like kale.

Squash and Pumpkins

Peak Availability: Sep–Nov

Nutrition: The bright orange color of winter squashes signals their richness in beta-carotene and Vitamins A and C.

Selection and Storage: September is the debut for hard-skinned winter squashes like butternut, acorn, and spaghetti squash, as well as pumpkins. These varieties can be stored for long periods in a cool, dark place. For fresh consumption, choose squash with firm, unblemished skin.

Culinary Uses: These vegetables are perfect for roasting, pureeing into soups and pies, or cubing for casseroles. The versatility of a vegetable like butternut squash makes it a staple for fall dishes like Roasted Butternut Squash Soup or a Butternut Squash and Orzo Salad.

Harvesting, Storing, and Cooking September’s Bounty

To get the most out of your September produce, consider these practical tips. For home gardeners, cool-weather crops like carrots, beets, and radishes can be sown in early September for a late-fall harvest. For those looking to preserve the season’s peak, many fruits and vegetables can be frozen or pickled. Zucchini, bell peppers, and berries can be washed, sliced, and frozen for use in smoothies and soups during the winter months.

  • Pears: Unlike most fruits, pears ripen best off the tree. Keep them at room temperature until they yield slightly at the neck, then refrigerate.
  • Beets: When selecting beets, choose small or medium-sized ones with smooth, firm skin. If the greens are attached, they should be bright green and not wilted. Store the greens and roots separately for optimal freshness.
  • Carrots: Look for carrots that are firm and evenly shaped. Avoid those that are split or limp. If the greens are still attached, they should be vibrant and not decaying.
  • Tomatoes: To ripen green tomatoes from the garden, simply leave them on the counter. They will eventually turn red and can be used for sauces or salsas.

Regional Variations in September Produce

While the list above covers produce widely available across the U.S., seasonality varies significantly by geography.

  • Northeast & Midwest: This is the heart of apple picking season. Apples, pears, cranberries, pumpkins, cabbage, and hearty greens are abundant. Farmers’ markets are bustling with cider, pies, and jams.
  • Southeast: This region enjoys an extended summer, with late-season peaches, watermelon, and bell peppers still plentiful. Sweet potatoes, okra, and regional specialties like fried green tomatoes are also prominent.
  • Southwest: This area is famous for its late-season specialty produce, including figs, pomegranates, and prickly pears. September is also the peak for a variety of hot and green chiles, such as Hatch chiles, which are perfect for salsas and stews.
  • West Coast (California, Pacific Northwest): The harvest continues with abundant grapes, berries, and figs. Stone fruits like peaches and plums may still be available, along with a wide range of specialty produce like kiwi and persimmons.

Frequently Asked Questions (FAQ)

What vegetables can I plant in September?

September is an excellent time to plant cool season crops in many regions. Fast-maturing greens like lettuce, arugula, and kale, as well as root vegetables like carrots and radishes, can be sown for a fall harvest.

Is sweet corn still good in September?

Yes, sweet corn is at its peak in July and August, but it remains a delicious, strong crop throughout September in many regions before the season ends.

What’s the difference between summer and winter squash?

Summer squash, such as zucchini and yellow squash, has a soft, edible skin and a shorter shelf life. Winter squash, including butternut, acorn, and pumpkin, has a hard skin that allows it to be stored for months. It is typically harvested in the fall.
