As summer starts to transition into fall, there’s no need to bid farewell to your gardening endeavors. In Zone 6, August is the perfect time to sow a selection of cool-season plants that thrive in the brisk autumn air. With proper planning, you can enjoy a bountiful harvest that continues well into the fall months. In this guide, we’ll explore the top cool season plants to plant in August, highlighting their preferences, companion plants, days to harvest, and growth expectations.

1. Kale (Days to Harvest: 55-75)

Kale thrives in cool temperatures, making it an excellent candidate for your late summer garden. It prefers full sun but can tolerate partial shade. Keep in mind that kale’s flavor actually improves with a touch of frost. Consider planting it alongside beets, carrots, or onions as companions.

2. Spinach (Days to Harvest: 37-45)

Spinach loves the cooler weather of early fall. It’s versatile and can grow in both full sun and partial shade. Pair spinach with lettuce, radishes, or carrots for a complementary garden bed. Regular harvesting of outer leaves encourages continuous growth.

3. Lettuce (Days to Harvest: 50-70)

Lettuce varieties, such as leaf lettuce or romaine, are perfect for quick salads and sandwiches. They appreciate cooler temperatures and can thrive in partial shade. Plant lettuce with radishes, onions, or carrots to maximize space and promote healthy growth.

4. Radishes (Days to Harvest: 20-30)

Radishes are a speedy addition to your fall garden. They prefer full sun but can tolerate some shade. Their quick growth makes them excellent companions for slower-growing plants like carrots and spinach.

5. Carrots (Days to Harvest: 55-80)
