This guide explores the best plants to cultivate in August, providing insights on optimal gardening practices to ensure successful growth.

Vegetables To Plant

August offers a plethora of opportunities for planting vegetables that can thrive even as cooler temperatures hint at fall. Here are ten robust options, each with specific growth and temperature tolerances.

Kale

Kale is a nutrient-dense leafy green that flourishes in the cooler months. It’s tolerant to frost, making it an ideal choice for late summer planting. In Zone 8b, you can sow seeds directly into the garden until mid-August. As the temperature cools in September and October, the flavor of the kale will sweeten. Expect foliage to grow well into the winter, providing fresh greens even after frost.

Spinach

Traditionally sown in early spring, spinach can be successfully planted in August for a fall harvest. Spinach is a cool-weather crop that tolerates light frosts, enhancing its flavor. For mid to late-August sowing, consider selecting fast-growing varieties like ‘Quick Sun’ or ‘Space.’ The quick maturation makes starting in August a viable choice, yielding a harvest before the first hard freeze.

Swiss Chard

Swiss chard is known for its vibrant stems and broad leaves, making it not just nutritious but visually appealing. In Zone 8b, chard can be sown directly into the soil from early to late August. It thrives in partial shade, and mature plants can withstand temperatures as low as 20°F. Additionally, chard is a versatile green that can continue producing through the fall, providing continuous harvests of tender leaves.

Beets

Beets are another great crop for August planting, as they can withstand some cooler temperatures while developing their sweet, earthy roots. Sow beet seeds in late August, ideally by the 15th, for a bountiful fall harvest. Beets prefer well-drained soil and consistent moisture; they should be spaced properly to ensure they have room to grow. Moreover, baby beet greens can also be harvested for salads, providing dual purposes with one planting.

Carrots

Carrots can also be planted in August for a late fall harvest in Zone 8b. They thrive in loose, sandy soil and cooler temperatures, making the late summer months perfect for sowing. Choose shorter varieties like ‘Little Finger’ if you’re time-constrained; they mature faster and are less likely to be affected by late-season pests. Carrots can be harvested from October through early winter, depending on your planting date.

Radishes

Radishes are among the fastest-growing crops and can be sown every few weeks for ongoing harvests. In Zone 8b, early August sowing allows enough time for a full crop before colder weather sets in. They prefer full sun and can tolerate some shade, but be cautious about soil moisture as overly wet conditions can cause them to split. Delightfully crisp and peppery, they’re a fantastic addition to salads or can be pickled for added zing.

Turnips

Turnips grow quickly and are another excellent crop for August planting. They can be sown until mid-August and will mature in approximately 30-60 days, depending on the variety. They are cold-hardy, tolerating temperatures down to 20°F, and both the roots and greens are edible. Requiring little maintenance other than consistent water and sunlight, turnips are an excellent choice for a gardener looking to maximize their late-summer planting efforts.

Broccoli

Broccoli can be planted in August in Zone 8b for an early winter harvest. Start seeds indoors about 6-8 weeks before the last frost or direct sow them in well-prepared soil. Broccoli thrives in cooler temperatures and is an excellent source of vitamins C and K. Keep the soil consistently moist and consider applying mulch to maintain soil temperature. Broccoli performs best when established with plenty of sunlight, ideally 6-8 hours daily.

Cabbage

Cabbage, known for its form and flavor, is another cool-season vegetable that can be planted in late August. Sow seeds directly into the garden or purchase seedlings for a controlled start. Cabbage is frost-tolerant, meaning it can take light freezes without damage. With proper spacing and soil care, you’ll be rewarded with dense heads that can be harvested in late fall or early winter.

Peas

Peas are a delightful choice for a late summer garden and can be successfully planted in August for a fall crop. Snap and snow pea varieties thrive in cooler weather and can be sown undercover or directly into the soil. Peas should be spaced adequately to allow for climbing varieties.
