As summer fades into fall, many gardeners believe their planting days are over. But experienced food growers know September offers a golden opportunity to extend your growing season and prepare for next year’s bounty. Planting vegetables in September can fill gaps in your garden, provide quick harvests before winter sets in, and set the stage for early spring crops. Whether you’re a seasoned gardener or just starting out, these 15 vegetables will help you make the most of your garden space. From leafy greens to root vegetables, there’s something for every taste and climate.
I always plan space for over-winter crops that will give me a harvest early in the year, during the “hungry months”, and, where the soil can withstand giving me extra, I also fill gaps where I’ve harvested other produce with quick-growing crops that’ll give me a harvest before the frost sets in.
1. Arugula
Arugula, also known as rocket, is a fast-growing leafy green perfect for September planting. Its peppery flavor adds a kick to salads and sandwiches. Arugula can be ready to harvest in as little as 40 days, making it an ideal choice for quick results before winter arrives.
2. Beets
Beets are versatile root vegetables that thrive when planted in September. They can withstand light frosts, making them perfect for fall gardens. Both the roots and leaves are edible, offering two harvests from one plant. Beets are rich in nutrients and add vibrant color to your meals. I love beet tops. They’re delicious when they’re youngin salads and then, once they’re a little more mature, I use them wherever I’d use cabbage, kale, and other leafy greens.

Broccoli is a cool-season crop that performs well when planted in early September. It takes about 50-60 days to mature, providing a nutritious harvest before winter sets in. Broccoli is packed with vitamins and fiber, making it a healthy addition to your fall menu.

These miniature cabbages are ideal for September planting. Brussels sprouts prefer cooler temperatures and can even survive moderate frosts.

Mine happily survive, even with a covering of snow, deep into winter until I’m ready for them.
