August in Zone 7
August in Zone 7: second season planting begins. Set out fall brassica transplants; direct sow fall greens.
Quick answer · Updated July 2026
August is the fall-garden kickoff in Zone 7. Transplant broccoli, cabbage, and cauliflower in early August; direct-sow bush beans, carrots, and beets by mid-month; then sow kale, turnips, lettuce, and spinach in the second half. With first frost around October 15–November 15, count back each crop’s days to maturity plus about two weeks — the table below gives last-safe planting dates for zones 7a and 7b.

Gardening in August in Zone 7
August is peak growing season in Zone 7. With a frost-free stretch running roughly Late March – mid April to Mid October – mid November — about 200–225 days — the garden is in full swing, balancing succession sowing with steady harvests.
This month, Zone 7 gardeners are getting Broccoli, Cabbage, Kale, Kohlrabi, Lettuce, and Spinach into the ground or under lights while harvesting Tomatoes, Peppers, and Cucumbers from earlier plantings. The task cards below give spacing, depth, and timing for each.
About August in the garden
August transitions from peak summer to late summer. Heat continues but days are shortening noticeably. Fall crop planting is urgent in cold zones, and warm-zone gardeners begin planning for fall gardens. Preserving harvests becomes a priority.
Peak tomato and pepper harvest; urgent fall planting in cold zones; canning and preserving; transplanting fall brassicas; planting spring bulbs ordered early.

The Zone 7 fall garden starts in August: last-safe planting dates
The single most useful number for August planting in Zone 7 is your first-frost date: around October 15–November 1 in zone 7a, and November 1–15 in the warmer 7b. Take any crop’s days-to-maturity from the seed packet, add roughly 14 days (the “fall factor” — growth slows as days shorten), and count backward from your frost date. If today lands before that date, you can still plant it. That simple math is what separates a productive fall garden from a bed of half-grown seedlings killed by frost.
Work the month in waves. Early August: transplant fall brassicas (broccoli, cabbage, cauliflower) and make the last sowing of bush beans and carrots. Mid-August: beets, chard, and kohlrabi. Late August: kale, collards, turnips, Asian greens, and the first lettuce — then keep succession-sowing lettuce and spinach into September. Gardeners in 7b can run every window about two weeks later than 7a.
The real enemy of August sowing isn’t frost — it’s 90°F soil. Lettuce and spinach simply won’t germinate hot. Sow a touch deeper than spring, water morning and evening, shade rows with 30–40% shade cloth until seedlings are up, and pre-chill spinach seed in the refrigerator for a week before sowing. Don’t forget flowers: sow pansies and violas now for fall color, and 7b gardeners can squeeze in one last fast round of zinnias in the first week of the month.
Zone 7 last-safe planting dates (count back from first frost)
| Crop | Last safe date — 7a | Last safe date — 7b | Notes |
|---|---|---|---|
| Bush beans | Aug 5 | Aug 20 | 50–60 days; finish harvest before frost |
| Broccoli (transplants) | Aug 10 | Aug 25 | Shade young transplants their first week |
| Cabbage (transplants) | Aug 10 | Aug 25 | Tolerates frost; sweetens in cold |
| Carrots | Aug 10 | Aug 25 | Frost makes fall carrots sweeter |
| Beets | Aug 15 | Sep 1 | Harvest roots and greens |
| Kohlrabi | Aug 15 | Sep 1 | One of the fastest fall brassicas |
| Kale & collards | Aug 25 | Sep 10 | Flavor improves after frost |
| Turnips | Aug 25 | Sep 10 | Roots plus cut-and-come-again greens |
| Lettuce | Sep 1 | Sep 15 | Succession-sow weekly; shade to germinate |
| Spinach | Sep 1 | Sep 15 | Pre-chill seed; overwinters under cover |
| Radishes | Sep 15 | Oct 1 | 25–30 days — the latest sowing of all |
Dates assume first frost around Oct 15–Nov 1 (7a) and Nov 1–15 (7b), with a ~2-week fall factor already included. Adjust to your local microclimate.
Beating August heat at germination time
- ✓Sow fall seeds slightly deeper than in spring — the soil is cooler and moister an extra half-inch down.
- ✓Cover freshly sown rows with 30–40% shade cloth (or a board for 2–3 days) until seedlings emerge.
- ✓Water lightly twice a day; a crusted-dry seedbed is the #1 cause of failed August sowings.
- ✓Pre-sprout spinach: refrigerate seed for 5–7 days, then sow in the evening and keep constantly moist.
- ✓Start lettuce indoors under lights or in an air-conditioned room and transplant out at 2–3 weeks old.
- ✓Order garlic now — Zone 7 plants it in October, and the best varieties sell out by early fall.

Maintenance
🌿 Sow outdoors
Direct sow fall lettuce, spinach, and radishes (mid-August)
Surface-sow or ⅛ inch deep; thin to 8 inches for heads, 4 inches for cut-and-come-again.
Sow ½ inch deep, 2 inches apart; germinates best at 50–65°F; thin to 6 inches.
Sow ½ inch deep, 1 inch apart; thin to 2 inches; ready in 25–30 days.
Surface-sow in wide bands; thins itself as it grows; bolt-prone in heat — shade if needed.
🪴 Transplant
Transplant fall broccoli, cabbage, and kale
Sow ¼ inch deep; transplant at 4–6 weeks when 4–5 inches tall; space 18 inches apart.
Sow ¼ inch deep; harden off well before transplanting; space 12–18 inches apart.
Sow ¼ inch deep directly or in trays; very cold-hardy; direct sow works well in cool soil.
Sow ¼ inch deep; harvest when 2–3 inches in diameter for best texture.
📌 Aim for harvest before first frost.

General August tasks
These apply broadly regardless of zone — a useful checklist alongside the zone-specific tasks above.
- ✓Direct sow fall spinach, arugula, and lettuce in cold and temperate zones
- ✓Transplant fall broccoli, kale, and chard starts
- ✓Plant fall-bearing strawberries
- ✓Order spring bulbs for fall planting
- ✓Harvest and preserve: tomatoes, peppers, cucumbers, beans
- ✓Sow cover crops in empty beds to suppress weeds and build soil
- ✓Reduce fertilizing on perennials to encourage hardening-off before winter
- ✓Deadhead spent flowers to extend bloom or let seed heads form for birds
⚠ Watch-outs for August
- ⚠Late August is the last chance to plant fall crops in cold zones (Zones 3–5) — time is short
- ⚠Tomato late blight can spread rapidly in cool, wet August conditions — inspect daily
- ⚠End-of-season exhaustion in squash and cucumber plants — pull when productivity drops
- ⚠Fall armyworms arrive in the South in August — inspect grass and leafy crops
August in Zone 7: common questions
What can I plant in August in Zone 7?＋
August is the fall-garden kickoff in Zone 7. Transplant broccoli, cabbage, and cauliflower in early August; direct-sow bush beans, carrots, and beets by mid-month; then sow kale, turnips, lettuce, and spinach in the second half. With first frost around October 15–November 15, count back each crop’s days to maturity plus about two weeks — the table below gives last-safe planting dates for zones 7a and 7b.
When is the last and first frost in Zone 7?＋
Zone 7 typically has its last spring frost around Late March – mid April and its first fall frost around Mid October – mid November, giving a growing season of roughly 200–225 days. Always check a local frost-date source, since microclimates vary.
Is August too late to start a garden in Zone 7?＋
No — August is the start of Zone 7’s second growing season. With first frost still 10–14 weeks away, there’s time for beans, carrots, beets, brassicas, and a long run of fall greens. Many crops, like kale and carrots, actually taste better grown into cool fall weather.
What is the last day to plant bush beans in Zone 7?＋
About August 5 in zone 7a and August 20 in zone 7b. Bush beans need 50–60 frost-free days plus time to pick the crop, so count back from your first-frost date (roughly Oct 15–Nov 1 in 7a, Nov 1–15 in 7b).
How do I figure out fall planting dates in Zone 7?＋
Take the crop’s days-to-maturity from the seed packet, add about 14 days because growth slows as days shorten, and count backward from your first-frost date. The result is the last safe planting day — anything sown before it has time to mature.
What's ready to harvest in August in Zone 7?＋
In August, Zone 7 gardeners are typically harvesting Tomatoes, Peppers, and Cucumbers. Pick regularly — frequent harvesting keeps most crops producing longer.
