Ontario Summer Produce Guide: What Fruits Are in Season in Ontario This Summer?

Ontario summer fruit peaks from June to September. Local farms offer many fresh picks during these months. Field strawberries start in early June and last all summer. In late September, you can find hardy melons. The warm Ontario sun produces some of the best-tasting fruit in the country, and knowing when each variety ripens helps you eat better all season long. Many people like to browse seasonal produce to find the best items each week.

Which berries grow in Ontario?

Strawberries are the first fruit to arrive. Local field strawberries stay in season all summer. They are often smaller and sweeter than fruit shipped from far away. Raspberries and blueberries follow in July. These berries stay in season until September based on the Foodland Ontario availability guide.

July and August are peak months for black raspberries and currants. These fruits have short seasons. It is best to buy them as soon as they appear. Checking local harvest dates helps you find fruit at its peak. When you buy in-season berries, you get better flavor and more nutrients.

When are stone fruits ready?

Stone fruits grow well in the warm Ontario sun. Peaches, plums, and cherries ripen in July and August. Experts at Sobeys find that July and August are the top months for these fruits. Most types stay available through September. This includes late-season nectarines and apricots.

The Niagara region is famous for these crops. The climate there helps stone fruits thrive. Peaches from this area are juicy and sweet. Plums come in many colors, from deep purple to bright yellow. Cherries have a shorter season that often ends by late August. You can find both sweet and sour cherries during this peak.

What melons can I find in late summer?

Watermelons and muskmelons are late-summer treats in Ontario. These large fruits need high heat to grow. They usually come out in July and stay in season until September. Local watermelons are crisp and full of juice. They are a great snack for hot days.

Muskmelons, or cantaloupes, have a rich scent and sweet orange flesh. These melons are best when they feel heavy. Since they grow in Ontario, they do not sit on a truck for long. This lets them stay on the vine to get more sugar and flavor.

Top Summer Vegetables Grown in Ontario

Ontario farms grow a wide range of fresh vegetables during the warm months. Most local crops are ready between July and September. This is when the soil is warm and the sun is bright. Buying vegetables in season gives you better taste and value. It also helps support the 200+ local Ontario farmers and producers that grow our food. Many families use an Ontario summer produce guide to plan their meals around the freshest picks. Picking crops at their peak means they have the most nutrients and the best flavor.

Peak Season Staples

Sweet corn and field tomatoes are the stars of the Ontario summer. According to Foodland Ontario, sweet corn is at its best from July through September. During this time, the corn is sweet and tender because it is picked at peak ripeness. Field tomatoes also reach their full flavor in these same months. While you can find greenhouse tomatoes all year, the sun-ripened field varieties have a deep, rich taste. These staples are often more plentiful in late summer, which can lead to lower prices. This is a great time to buy in bulk for freezing or canning.

Versatile Summer Crops

Ontario soil produces many other crops that fill your plate with color. Bell peppers, zucchini, and cucumbers grow well all season long. You can find green beans and kale from early summer until the first frost. In August, eggplant and celery join the mix. These vegetables are useful in many ways. You can use them in fresh salads, hearty stews, or even on the grill. Beets and radishes add a crisp bite to summer meals. Leafy lettuce and summer squash also thrive in the warm sun. Choosing these local options helps reduce the distance your food travels to reach your table.

Early Summer Gems

Some vegetables appear early and have a short stay. Asparagus is one of the first crops to arrive in the spring. However, it is usually gone by the end of June. Garlic scapes are another treat found only in June and July. They have a mild garlic taste and a unique curly shape. Hardneck garlic bulbs follow soon after in July and August. These early crops remind us that the peak harvest months for Ontario produce have finally started. You should enjoy these gems while they last since their season is quite short. Knowing when each crop arrives helps you eat the best food all summer long.

You can also find crops like celery and beets that stay fresh for a long time. Storing your summer haul in a cool, dark place keeps it crisp for days. This helps you get the most out of every grocery delivery. When you buy local, you get food that was in the field just a short time ago.

Month-by-Month Ontario Summer Produce Calendar

Summer in Ontario brings a fresh wave of crops every month. The main growing season runs from June through September by the Foodland Ontario produce guide. During this time, local farms harvest all types of food from sweet berries to hearty squash. Knowing when each item is ready helps you get the best taste and value. Fresh food that is in season often tastes better and costs less.

Early Summer Crops in June

June marks the start of the local harvest. Asparagus and rhubarb are the first items to arrive at farm stands. You can also find field strawberries and radishes late in the month. Garlic scapes appear for a short time in late June and early July. These early crops show that the peak season is near. Most June food is mostly leafy greens and early root crops that grow well in mild weather.

Buying at the start of the season ensures you get the first pick of the year. This is a great time to find crisp stalks and tender greens. You can learn more about how Tre'dish works to bring these early crops from the farm to your kitchen. Our partners focus on freshness so you get the best food every week.

Peak Season Harvest for July and August

July and August are the best months for fresh food in Ontario. The summer heat helps stone fruits like peaches, plums, and cherries ripen to their peak. Berries such as blueberries and raspberries are also at their best. For food from the soil, this is the time for corn, field tomatoes, and peppers. Zucchini and cucumbers are also plenty during these two months. Many people use this time to buy in bulk for canning or freezing.

The middle of summer offers a great mix for your food cart. Most field crops reach full size by late July. You will notice that tomatoes and peppers have more taste during this peak window. It is the best time to try new recipes with local corn or eggplant. Having plenty of food usually means you get the best value for your money during these weeks.

Late Summer and Fall Shift in September

As the air cools in September, the harvest shifts. You will still see raspberries and field tomatoes in the markets. But new items like apples, pears, and grapes start to show up. This is also the time for hearty winter squash and pumpkins. These crops can last much longer than soft summer fruits. They provide the base for warm meals as the weather turns colder.

September is a special month because it bridges two seasons. You get the last of the heat-loving crops and the first of the cool-weather ones. It is a busy time for Ontario farmers as they bring in the final summer fruits. You can still find peppers and eggplant along with the first harvest of apples. This mix makes it a great month to explore new local tastes.

How to Select and Store Fresh Ontario Produce

Buying in-season Ontario produce ensures you get the best taste and value. Local crops like corn, peaches, and tomatoes are picked at peak ripeness right before they reach you. This leads to better flavor than produce shipped from far away. Use this Ontario summer produce guide to find the freshest items and keep them tasty for longer.

At the peak of the season, crops are more abundant and prices may drop. This is a great time for bulk buying to freeze or preserve your favorites for the winter months. You can browse seasonal produce on the Tre'dish store to see what is now in stock from local farms.

Find the best summer crops

When you pick your produce, use your senses to find the best items. For stone fruits like peaches and plums, look for fruit that gives a bit when pressed near the stem. Berries should have a deep, even color without soft spots or mold. When you pick corn, the husks should be bright green and feel damp, while the silk ends should be brown and sticky.

Field tomatoes are a star of the Ontario summer. Choose tomatoes that feel heavy for their size and have a strong, sweet smell. Avoid any with bruised skins or cracks. As Foodland Ontario notes, field tomatoes are most available from July through September.

Smart storage for longer life

Proper storage stops food waste and keeps your produce fresh. Keep berries in the fridge and do not wash them until you are ready to eat. Water causes berries to mold fast. For corn, keep the husks on and store the ears in the fridge to keep the kernels sweet and juicy.

Never put fresh tomatoes in the fridge. The cold air can make the flesh mealy and dull the flavor. Store them on the counter at room temp instead. Leafy greens and herbs should go in the crisper drawer with a damp paper towel to stay crisp. Proper cooling is key, as the Mayo Clinic says that right storage helps keep the nutrients in your food.

Steps to preserve the summer harvest

  1. Wash and dry. Rinse your produce in cool water to remove dirt. Pat fruits and vegetables dry with a clean towel.
  2. Prep for freezing. Slice large fruits like peaches or hull your strawberries. Blanch vegetables like corn or beans in boiling water for two minutes, then cool them in ice water.
  3. Flash freeze. Spread the pieces in a single layer on a tray. Put the tray in the freezer for two hours until the pieces are hard.
  4. Seal and store. Move the frozen items into airtight bags or containers. Label them with the date and type of produce.
  5. Try canning or pickling. Use extra cucumbers to make pickles or turn berries into jam. These ways keep your summer favorites safe to eat for up to a year.
