What to Plant in August: Late-Summer Winners for Your Garden
August gardening often feels like cooking pasta al dente—it's all about timing and finesse. I've spent years deciphering this delicate dance, often in sweaty August afternoons, beer in hand, dirt under nails. Now, let me spill some hard-earned wisdom about what to plant in August for a garden that's lush until frost.
Leafy Greens: A Second Chance for Salad Lovers
Yes, leafy greens flourish even in late summer heat, despite popular misconceptions. Quick-growing greens do remarkably well, soaking up August warmth without bolting immediately.
- Arugula: Plant seeds directly into moist, compost-rich soil. Harvest young leaves in just 3 weeks.
- Spinach: Choose heat-resistant varieties like 'Bloomsdale'. They'll thrive with just a bit of afternoon shade.
- Swiss Chard: Bright stems, earthy flavor. Easily my favorite for sautéing.
"Leafy greens planted in late summer mature quicker, have fewer pests, and taste markedly sweeter in cooler autumn nights."
Root Vegetables: Time to Go Underground
I've found root veggies sown in August develop superb depth and sweetness as temperatures dip.
- Carrots: Opt for varieties like 'Nantes' or 'Danvers'. Remember—loose, rock-free soil means straighter carrots. Trust me, I've learned this the crooked, frustration-filled way.
- Beets: Quick and forgiving, beets planted now deliver tender, vibrant roots by early fall.
- Radishes: The gardener's instant gratification. Ready in under a month.
Brassicas: The Cool-Weather Crew
Brassicas planted in August mature into the cool days of autumn, improving dramatically in flavor. Broccoli harvested after a light frost is particularly delightful.
- Kale: Hardy, flavorful and nutritionally dense. If you haven't tried kale chips yet, you're missing an indulgently crunchy treat.
- Cauliflower and broccoli: Start seeds indoors now, transplant in two weeks. Keep seedlings shaded until established.
- Cabbage: Choose smaller, faster-maturing varieties like 'Caraflex' or 'Early Jersey Wakefield'. Coleslaw never tasted better.
Herbs: Extending the Flavor Season
August is ideal for planting herbs that'll carry flavors into autumn's culinary adventures.
- Cilantro (Coriander): Prefers cooler weather. Planted now, it'll burst into lush growth just as your tomatoes peak—perfect salsa synergy.
- Dill: Rapid growth and subtle, citrusy flavor. Fresh dill sprinkled on grilled fish? Life-changing.
- Basil: Trickier, yes. But quick-growing 'Genovese' sown now will produce fragrant leaves before fall's chill arrives.
Late-Summer Flowers: Beauty With a Purpose
Flowers planted now not only add color but attract beneficial pollinators to your garden. Butterflies and bees clearly appreciate late bloomers as much as we do—with probably less wine involved.
- Calendula: Bright blooms delightful in salads or herbal salves.
- Borage: Star-shaped blue flowers, absolutely buzzing with bees. Edible flowers taste faintly of cucumber.
- Nasturtium: These peppery, vibrant flowers liven up any salad bowl. Easygoing enough for beginners.
"Planting the right crops in August extends your gardening season, nourishes your kitchen, and lets you savor the fleeting, warm days before autumn truly sets in."
So, instead of lamenting August heat, grab your seeds, step into the garden, and relish the chance at extending summer abundance. Every year, this late planting feels like cheating time itself—deliciously.

Frequently Asked Questions about August Gardening
Which vegetables thrive when planted in August?
August offers ideal planting conditions for leafy greens such as kale, Swiss chard, and spinach, which prefer slightly cooler temperatures for vigorous growth. Fast-growing root vegetables like radishes, beets, and carrots also benefit from a late-summer planting, maturing comfortably as autumn approaches.
Can herbs be successfully planted during August?
Absolutely. Hardy herbs like basil, cilantro, and parsley flourish when planted in August, taking advantage of warm soil and sunlight to encourage healthy germination and flavorful foliage. Regular watering helps ensure steady growth during warmer days.
Are there any flowers suitable for August planting?
Yes, ornamental flowers such as marigolds, calendulas, and pansies can be planted in August, providing vibrant blooms into the early fall season. Select varieties with shorter maturity times to ensure blossoms before temperatures dip below 50°F (10°C).
How should the soil be prepared for planting in August?
Prepare garden soil by mixing in a generous amount of compost or well-aged organic matter, enhancing soil structure, moisture retention, and nutrient availability. Incorporate amendments to a depth of about 8 to 10 inches (20 to 25 cm) to facilitate vigorous root development.
How much water is necessary for plants established in August?
Newly planted crops in late summer depend on consistent watering to establish healthy root systems. Aim for approximately 1 inch (2.5 cm) of water weekly, adjusting as needed based on rainfall patterns and soil moisture conditions. Drip irrigation or targeted watering early in the morning encourages deeper root growth and reduces disease risk.
Should mulch be used for plants started in late summer?
Applying a layer of organic mulch, such as straw or shredded bark, around August-planted vegetables, herbs, and flowers helps retain moisture, suppress weed growth, and moderate soil temperature. Maintain a mulch layer around 2 to 3 inches (5 to 7.5 cm) thick, leaving space around plant stems to prevent rot.
Do plants established in August require fertilization?
A balanced, slow-release organic fertilizer or liquid feed can enhance growth and productivity of plants set out in August. Apply fertilizers sparingly and adhere closely to recommended application rates on product labels to avoid overstimulating late-season plant growth.
Knowing what to plant in August means seizing opportunity—sowing hardy greens and root veggies like kale, carrots, and spinach ensures delicious harvests that linger into autumn. Choose quick-growing herbs such as cilantro or cool-season blooms like snapdragons and pansies to maintain color and aroma as summer winds down. August planting is about timing: plant thoughtfully, water regularly, mulch generously, and you'll reap vivid flavor and beauty well beyond summer's close. Gardening in August isn’t slowing down; it's savoring the best that late-summer soil can offer.
