Vegetables to Plant in August in Virginia

August is a critical month for gardeners in Virginia to focus on planting vegetables that thrive in the late summer and early fall growing season. Due to Virginia’s climate, which features hot summers and mild to cool autumns, many cool-season crops can be successfully planted for a fall harvest.

Vegetables well-suited for August planting include leafy greens, root vegetables, and certain brassicas. These crops benefit from the warming soil early in the month and cooler air temperatures as September approaches, which can enhance flavor and reduce bolting.

Key vegetables to plant in August are:

  • Leafy Greens: Spinach, lettuce, Swiss chard, arugula, and kale can be sown from seed or transplanted as seedlings. These greens prefer cooler temperatures and can mature quickly for a fall harvest.
  • Root Vegetables: Carrots, beets, radishes, and turnips respond well to late summer planting. They require well-drained soil and consistent moisture for optimal root development.
  • Brassicas: Broccoli, cauliflower, cabbage, and Brussels sprouts can be started from transplants in August for fall or early winter harvest. These crops require fertile soil and may benefit from protection against pests.

Additionally, quick-maturing crops like green beans and bush beans can still be planted early in August for a final harvest before frost.

Vegetable Planting Method Days to Maturity Notes
Spinach Seed or transplant 35-45 days Prefers cooler weather; mulch to retain moisture
Carrots Seed 70-80 days Loose, sandy soil ideal; thin seedlings
Broccoli Transplant 55-70 days Fertilize well; watch for cabbage worms
Radishes Seed 25-30 days Fast-growing; good for succession planting
Lettuce Seed or transplant 30-60 days Partial shade helps extend harvest

Herbs to Plant in August in Virginia

August provides an excellent opportunity to plant a variety of herbs that will either mature before the first frost or establish well for harvesting into the fall and following spring. Many herbs prefer warm soil for germination and can tolerate the heat of late summer, making this a prime time for sowing seeds or transplanting seedlings.

Consider planting the following herbs in August:

  • Basil: While it prefers warmer temperatures, planting basil early in August can still yield fresh leaves through early fall. Pinching back encourages bushier growth.
  • Cilantro: This herb thrives in cooler weather and can be planted in late August for a fall harvest. It bolts quickly in heat, so planting later helps avoid premature flowering.
  • Parsley: Can be seeded or transplanted in August; grows well into fall and can overwinter with some protection.
  • Thyme and Oregano: Perennials that can be transplanted or propagated in August, allowing time for roots to establish before winter.
  • Dill: Sow seeds directly; this herb prefers cooler weather, so late August planting is ideal for fall use.

Maintaining consistent soil moisture and providing some shade during intense heat can improve herb establishment and yield.

Flowers to Plant in August in Virginia

August is a transitional month in Virginia gardening, ideal for planting certain annuals, perennials, and bulbs that will bloom in the fall or the following spring. Selecting the right flowers can extend the garden’s color well beyond summer’s end.

Good choices for August planting include:

  • Fall-blooming annuals: Marigolds, zinnias, cosmos, and ornamental kale can be planted to provide vibrant color into the cooler months.
  • Perennials: Planting perennials such as asters, sedum, and chrysanthemums in August allows them to establish roots before winter, ensuring strong blooms next year.
  • Bulbs: While spring-flowering bulbs are typically planted in the fall, some summer bulbs like tuberous begonias and gladiolus can be planted in early August for late summer or early fall blooms.

To support flower establishment in August’s heat, apply mulch to conserve moisture and consider supplemental watering during dry spells.

Planting Tips for August Gardening in Virginia

Successful August planting in Virginia requires attention to soil preparation, watering, and pest management to navigate the challenges of summer heat and prepare for cooler seasons.

  • Soil Preparation: Amend soil with compost or aged manure to improve fertility and moisture retention. Ensure good drainage to prevent root diseases.
  • Watering: Consistent watering is critical. Early morning irrigation reduces evaporation and fungal risks. Avoid overhead watering to minimize leaf wetness.
  • Pest and Disease Control: Monitor for pests such as aphids, caterpillars, and fungal diseases. Use integrated pest management techniques, including natural predators and organic treatments.
  • Succession Planting: Stagger plantings every two weeks for continuous harvest, especially with fast-maturing crops like radishes and leafy greens.
  • Shade and Mulch: Use shade cloth if necessary during extreme heat, and apply mulch to regulate soil temperature and conserve moisture.

Following these guidelines enhances plant vigor, maximizes yield, and ensures a productive garden as summer transitions
