Wondering what to plant in August? Even though summer is winding down, there’s still plenty of time to grow fresh vegetables before the season ends. Many cool-season crops germinate quickly, thrive in cooler temperatures and mature in time for a productive fall harvest. With the right selections, you can make the most of empty garden beds and extend your growing season well into autumn.

What to Plant in August: Key Takeaways

• What to plant in August includes fast-growing, cool-season vegetables that mature before the first fall frost.
• Crops such as peas, lettuce, radishes and leafy greens often perform better as temperatures begin to cool.
• Replanting harvested garden beds helps extend your harvest and makes the most of the remaining growing season.

Peas

This is one of your best options, because peas can produce a lot of food in a short time if you do it right. First, remember that peas are a legume, so they naturally fix nitrogen back into the soil. So you don’t necessarily have to replant your peas in the same bed you grew them the first time. Instead, you might try a late-summer pea replanting in a finished radish, lettuce, or carrot bed, or any garden crop that has finished. Planting peas in late summer means that your daily temperatures are likely to be cooler and the peas should really enjoy that. Move your trellis, stir up your soil, and place some peas in the ground before the growing season gets any older.

Lettuce

It’s such a delight to place freshly-picked lettuce on a sandwich, and you can plant some fast-growing leaf lettuce late in the growing season for fall delight. The lettuce should appreciate a break from summer’s heat, and you may even have less trouble in the fall with insects consuming your lettuce before you do.

Radishes

If you’re really running out of time but would still like to try growing something new before your local freeze date, radishes are a great option. Radishes can grow very fast, with some varieties finishing in under a month! The unique spicy flavor isn’t always everyone’s favorite, but there are definitely some good recipes out there that will utilize radishes well. You can’t beat radishes for speed!

Leafy Greens

You know that your “greens” thrive in that cool spring weather, but they should perform just as well in the fall. And since spinach, mustard greens, and kale are all pretty frost-hardy, they can even take a few chilly nights and still keep on growing during those warm autumn days. Plant your greens in late summer and enjoy them along with your fall apple harvest.

Frequently Asked Questions

Can I plant vegetables in August?

Yes. Many cool-season vegetables grow well when planted in August, especially in regions with a long growing season. Fast-growing crops such as lettuce, radishes, peas and leafy greens often mature before the first hard frost and may even produce better in cooler weather than they do during midsummer.

Can I replant the same crop in the same garden bed?

You can, but rotating crops is usually a better long-term practice. Moving crops to different beds helps maintain soil health and can reduce the buildup of pests and diseases that affect specific plant families.

Is August too late to plant vegetables?

Not necessarily. While warm-season vegetables like pumpkins and winter squash often need more time than August allows, many cool-season crops are well suited for late-summer planting and can provide a fall harvest before freezing temperatures arrive.

Final Thoughts

August doesn’t have to signal the end of your vegetable garden. By choosing fast-growing, cool-season crops, you can keep your garden productive well into fall. Whether you’re filling empty beds after an early harvest or simply looking for one last round of fresh vegetables, planting in August is a simple way to extend your growing season.
