If you haven’t gotten started on your summer vegetable garden yet, don’t worry—there are still plenty of veggies you can plant now for a late-season harvest! That means more fresh produce to enjoy through the fall, and with the help of our trusty freezers, many can be enjoyed well through winter and spring. You can find all kinds of seeds and starters for vegetables and fruits on our brand new webstore, so feel free to browse online and place an order for curbside pickup or citywide delivery.  

What Are The Best Vegetables To Plant In Summer?

Generally speaking, vegetables that can be planted in summer are either fast-growing and love the sun, or slow-growing and tolerant of the cooler temperatures in the fall. Many garden edibles can get scorched from the hot sun if planted too early, so it’s best to delay so that they’re ready to go once the temperature is less extreme. 

Late Summer Vegetables You Can Direct Seed

Many folks assume that spring is the best time for planting vegetable seeds, but every plant is different! So, if you want to start planting seeds in summer, there are more than a few good options for you to choose from. Here are the best late summer vegetables to plant in Simcoe through direct seeding:  

Beans: Perhaps one of the easiest and most kid-friendly veggies to grow, beans are always a favourite. Plus, they deposit nitrogen into the soil, which helps improve soil quality.

Beets: These hearty root vegetables make excellent comfort food, and their ultra-vibrant colour indicates super-high levels of vitamins, nutrients and antioxidants. Your beets will be ready for harvest around September or October. 

Broccoli: Even the pickiest of eaters aren’t likely to turn down a delicious bowl of broccoli cheese soup, or a Chinese beef and broccoli stir fry. Sow broccoli seeds in June for a harvest that’s ready right at the start of back-to-school season.

Carrots: Before you sow your carrot seeds, make sure your soil is super loose and free of rocks and compacted areas. If it’s all clumped together, the roots won’t grow long and pointy, so you’ll be left with stumpy, misshapen carrots. 

Leafy Greens: Lettuce, kale and spinach can all be sown directly into the soil in June. They don’t take too long to develop, and they thrive in cooler temperatures, so you can even get away with planting a second round in early autumn! 

Parsnips: Slow-growing parsnips need around four months to mature, but there’s no need to rush! Parsnips taste best if you harvest them after the weather has turned chilly. If we get hit with a few frosty nights in autumn, this will actually help them! Just make sure you pull them up before the ground freezes. 

Potatoes: While not technically seeds, you can put potato tubers in the soil in June to enjoy an autumn harvest. Wait for the plants to mature, turn brown, and wither, then leave them in the soil for another three weeks before pulling them up! Store them in a cool, dry spot, and don’t wash them before storing—this will cause them to rot. 

The Best Starter Plants For Late Summer Crops

The waiting game can get a little long when you directly seed certain plants, so sometimes it’s better to get a starter plant to transplant into containers or your garden bed. Here are some excellent starters to pick up later in the season: 

Zucchini: “Zoodles,” or spiralized zucchini noodles, are quickly gaining popularity as a delicious alternative to carb-heavy spaghetti. If (like many of us) you’ve been kinda overdoing it on the pasta lately, you’ll definitely enjoy having this tasty squash in your garden.

Celery: This ultra-healthy, crunchy veggie adds some great crunch to tuna salad, chilli, and stews, but it takes a pretty long time to develop from seed, so you may as well skip ahead and opt for a starter. 

Cucumbers: Technically, you can either transplant or direct seed cucumbers in June, but getting a starter will ensure you get to enjoy your harvest earlier in the season!

Peppers: With their thin, delicate skins, peppers aren’t too tolerant of chilly temperatures and will taste much better if they get lots of sunlight. Planting a starter in June will ensure these sun-loving veggies get peak sunshine in July and August, right when it counts. 

Tomatoes: We especially love growing small tomatoes in hanging baskets! The little fruits look like strings of colourful porch lights changing from green, to yellow, to red!


Fresh garden produce can be enjoyed well into autumn, and even early winter, if you pick the right crops and time them just right. If you have any questions about late-season planting, feel free to give us a call at the shop, and we’ll be happy to help!
