August · USDA Zone 7
summerWhat to plant in August in USDA zone 7
Summer planting guide for zone 7 (Virginia, North Carolina (mountains), Oklahoma, Tennessee) — a 200-day growing season with last frost around mid-April and first frost around late October / early November.
Sow outdoors in August — zone 7
Direct-sow these seeds into prepared garden beds or large containers. Soil temperature matters more than the calendar date — wait for a sustained warm-up before sowing tender crops.
- Fall salad, spinach, kale, lettuce, radishes, beets, carrots, turnips
Transplant in August — zone 7
Move hardened-off seedlings into the garden. Tender crops want soil above 16 °C and night temperatures consistently above 10 °C; cool-season transplants tolerate light frost.
- Fall brassicas, fall tomatoes (for second crop)
Harvest in August — zone 7
These crops should be ready or in active harvest in August for zone 7 gardens. Pick fruiting crops every 2-3 days to keep production going.
- Tomatoes, peppers, okra, squash, melons, peaches
Prep and planning — zone 7
- Order garlic for October-November planting
Universal August tasks
These apply across most US and UK gardens in August, regardless of zone.
- Sow autumn salad, spinach, kale, and oriental greens.
- Transplant fall brassicas (broccoli, cabbage, cauliflower) in zones 4-7.
- Preserve the summer harvest — can, freeze, dehydrate, or ferment.
- Order garlic and shallots for fall planting.
- Water consistently — uneven moisture splits tomatoes and bolts greens.
- Cut and dry herbs at peak flavor (just before flowering).
Why this works for zone 7
Zone 7 has average annual minimum temperatures of 0 to 10°F (-18 to -12°C) and a frost-free window from mid-April to late October / early November — about 200 growing days. Long enough season for sweet potatoes and okra. Many gardeners grow in fall + winter using row covers for greens and brassicas.
Dates are zone-wide averages. Local microclimates (south-facing slopes, urban heat, lakeside warmth, elevation) can shift the window by 1-2 weeks within the same zone.
UK gardeners — August
August is harvest peak and the gateway to autumn. Sow spring cabbage, winter lettuce, spinach, salad onions, and overwintering varieties of broad beans and peas. Harvest sweetcorn, tomatoes, beans, courgettes, soft fruit, and main-crop potatoes.
