Get ready to discover how to make the most of your late summer garden!
Vegetables Suitable for Late Summer Planting
In Zone 7, August presents an excellent opportunity to start a second round of vegetables that thrive in cooler weather, setting the stage for a productive fall garden. Many heat-sensitive crops can be planted now to mature during the cooler months.
Leafy greens such as spinach, kale, and Swiss chard are ideal choices because they germinate quickly and tolerate light frosts. Root vegetables like carrots, beets, and radishes also perform well when sown in late summer, as the soil remains warm enough for good seed germination.
To ensure success, it’s important to provide adequate water and consider using shade cloth during periods of intense heat to protect young seedlings. Additionally, thinning seedlings promptly will promote healthy growth and reduce competition for nutrients.
Herbs to Sow or Transplant in August
August is a prime time to plant herbs that prefer cooler temperatures or can establish themselves before the first frost. Many perennial herbs benefit from late summer planting, which allows their root systems to develop robustly before winter dormancy.
Herbs well-suited for planting in Zone 7 during August include:
- Cilantro, which prefers cooler weather and tends to bolt quickly in heat.
- Parsley, which can be sown from seed or transplanted and will continue growing into fall.
- Thyme and oregano, both hardy perennials that can be transplanted to establish a strong foothold.
- Chives, which thrive when planted as divisions or transplants now.
Proper spacing and consistent moisture are critical for herb seedlings, as crowded conditions can encourage disease.
Cover Crops and Soil Preparation
Planting cover crops in August is a strategic way to improve soil fertility and structure while preventing erosion during the off-season. In Zone 7, several cover crops can be sown in late summer to provide nitrogen fixation and organic matter.
Common cover crops suitable for August planting include:
- Crimson clover: a nitrogen-fixing legume that grows quickly and adds biomass.
- Winter rye: a hardy grass that protects soil and suppresses weeds.
- Hairy vetch: another legume that enhances nitrogen content and improves soil texture.
These crops should be tilled under before they set seed in the fall to maximize nutrient release and soil enrichment.
| Cover Crop | Benefits | Planting Notes |
|---|---|---|
| Crimson Clover | Fixes nitrogen, improves soil organic matter | Sow seeds in well-prepared soil; germinates quickly |
| Winter Rye | Prevents erosion, suppresses weeds | Plant in late August for best establishment before cold |
| Hairy Vetch | Enhances nitrogen, improves soil texture | Requires well-drained soil; plant early enough to establish |
Flowering Plants to Establish for Fall Color
August is an opportune time to plant certain flowers that will bloom during the fall, providing vibrant color in Zone 7 gardens. Cooler nights and shortening days trigger many species to flower in autumn, making late summer planting ideal.
Consider planting:
- Mums (Chrysanthemums), which are classic fall bloomers that establish well when planted in August.
- Asters, which offer a range of colors and attract pollinators.
- Ornamental kale and cabbage, which provide unique texture and color as temperatures cool.
- Marigolds, which can be sown from seed or transplanted for extended flowering.
When planting flowers in August, ensure soil is well-drained and amended with compost to support healthy root growth. Mulching will help retain moisture during the remaining hot days.
Timing and Care Tips for August Plantings
To maximize success in August plantings in Zone 7, careful timing and attentive care are essential. Early August plantings have more time to mature before frost, while late August sowings require selecting fast-maturing varieties.
Key tips include:
- Start seeds indoors or purchase transplants to get a head start, especially for cooler-season crops.
- Monitor soil moisture closely; late summer heat can cause rapid drying.
- Use mulch to moderate soil temperature and conserve moisture.
- Gradually acclimate transplants to outdoor conditions to reduce transplant shock.
- Keep an eye on pest pressure, as some insects remain active through late summer and early fall.
By adhering to these guidelines, gardeners can extend their growing season and enjoy a diverse harvest well into autumn.
Vegetables Suitable for Planting in August in Zone 7
In USDA Zone 7, August planting focuses primarily on fall crops that can mature before the first frost. The warm soil and lingering summer heat still support robust growth for many vegetables. To maximize yield, select varieties with shorter days to maturity and those tolerant of cooler fall temperatures.
Recommended vegetables to plant in August include:
- Leafy Greens: Spinach, Swiss chard, kale, and lettuce thrive when planted in late summer for a fall harvest.
- Root Vegetables: Carrots, beets, radishes, and turnips can be sown directly into the soil, as they mature quickly and tolerate cooler weather.
- Brassicas: Broccoli, cauliflower, cabbage, and Brussels sprouts benefit from August planting, allowing them to develop fully in the cooler fall climate.
- Peas: Snow peas and snap peas can be planted late in the season for a fall crop.
| Vegetable | Planting Method | Days to Maturity | Notes |
|---|---|---|---|
| Spinach | Direct seed or transplant | 40-50 | Prefers cooler temperatures; provide partial shade if very hot. |
| Carrots | Direct seed | 60-70 | Loose, well-drained soil essential for root development. |
| Broccoli | Transplant | 50-70 | Start seedlings indoors late July or buy transplants for August planting. |
| Radishes | Direct seed | 25-30 | Rapid growth; good for succession planting. |
| Swiss Chard | Direct seed or transplant | 50-60 | Heat tolerant and productive through fall. |
Herbs and Flowers to Plant in August in Zone 7
August is also an excellent time to plant certain herbs and flowers that will either mature in the fall or overwinter for early spring growth.
Herbs well-suited for August planting include:
- Parsley: Can be sown directly or transplanted; grows well in cooler fall temperatures.
- Cilantro: Prefers cooler weather, so planting in August helps avoid summer bolting.
- Thyme and Oregano: Perennial herbs that establish well in late summer for strong root systems.
