Fall Garden Guide for Zones 8–11: What to Plant Now

July 10, 2026

Gardeners in Zones 8 through 11 get a full fall growing season that cold-climate gardeners never see. While northern beds go dormant in September, warm-zone gardens are gearing up. The limiting factor is timing: sow too early and heat destroys germination, sow too late and crops don’t mature before the season closes.

For a full regional planting reference, our warm-zone vegetable gardening guides cover zone-specific planting calendars and variety picks for warm-climate growers.

Every fall planting decision here turns on two numbers: your first expected frost date and current soil temperature. Cool-season crops stall above 85°F soil temperature. In Zones 8 and 9, that threshold breaks in late August or early September. In Zones 10 and 11, summer heat lingers longer, pushing cool-season windows later by four to six weeks.

Zone 8 Fall Garden: Late August Through October

Zone 8 spans the Pacific Northwest coast, the Texas panhandle, and the inland Southeast. A fall frost arrives between mid-November (8a) and early December (8b), giving you 10 to 14 weeks from a September transplant date, depending on subzone. Summer heat breaks late here: resist sowing cool-season seeds until soil temperatures fall below 80°F.

Zone 8a: Frost Window November 15 – December 1

Start broccoli and cabbage transplants indoors around August 1. Move them outside when soil temps drop below 80°F, typically September 1–15 in most Zone 8a locations. Direct sow lettuce, spinach, arugula, and radishes starting September 15. Carrots and beets can go in as late as October 1 and still finish before first frost. Garlic planting runs October 15 through November 1.

Crops that won’t finish before frost in Zone 8a: winter squash planted after September 1, okra, and any warm-season succession started after mid-August.

Zone 8b: Frost Window December 1 – 15

The extra two to four frost-free weeks open a late warm-season slot through September. A final round of bush beans or a pepper flush is realistic if transplants are in the ground by September 1. Flip to cool-season crops by mid-October. Kale, collard greens, mustard greens, turnips, and beets all overwinter easily in Zone 8b without row cover.

Zone 9: September Through November

Fall is the primary growing season in Zone 9, not a secondary one. Cool-season crops planted in September produce through December and into January. The constraint in early September is still soil temperature: afternoon readings commonly stay above 85°F through mid-September in Zone 9a and a week or two later in warmer inland 9b areas.

Zone 9a: Transplants September 15, Direct Sow October 1

Set out transplants of broccoli, cabbage, cauliflower, and kale September 15–30. Direct sow lettuce, spinach, carrots, beets, and turnips from October 1 onward. Snow peas and snap peas planted October 1–15 mature for a December harvest. Garlic goes in October 15 through November 1.

A fall tomato crop is possible in Zone 9a if transplants go out August 1–15. Tomatoes set after September 1 won’t fruit reliably before cool nights close the window.

Zone 9b: Transplants October 1, Direct Sow October 15

Soil temps in coastal and southern Zone 9b stay above 80°F through early October. Target October 1–15 for cool-season transplants. In frost-free 9b locations, tomatoes planted in September and shaded through peak afternoon heat can continue producing into December. Direct sow lettuce, arugula, radishes, and spinach from October 15 onward.

Zone 10: October Through December

Zone 10 has no true off-season. Zone 10b is essentially frost-free year-round; Zone 10a sees light frost only on the coldest December or January nights. The result: warm-season crops run well into fall, and cool-season crops start later than in any zone covered here.

Zone 10a: First Frost Risk December – January

Transplant cool-season crops October 15 through November 1. Tomatoes set in September can produce through December if nighttime temps stay above 50°F. Direct sow carrots, beets, radishes, turnips, and leafy greens from November 1 onward. Peas planted November 15 mature for a February harvest.

Zone 10b: No Frost, Schedule by Soil Temperature

Timing in Zone 10b is governed by soil temperature and day length, not frost risk. Cool-season crops perform best when soil temps reach 65–75°F, typically November through January in most 10b locations. Tomatoes and peppers continue producing year-round in mild microclimates. Plan October planting for peak harvest in December and January.

Zone 11: October Onward

Zone 11 covers Hawaii, far South Florida, and similar tropical climates. Growing happens year-round, but October is when soil temperatures ease toward the range that gives cool-season crops their best quality: denser lettuce heads, sweeter carrots, less bitter kale.

Start cool-season transplants in October. Direct sow leafy greens from October 15 onward. Warm-season crops continue without interruption; fall is simply when a cool-season layer fits alongside them.

Soil temps in Zone 11 rarely fall below 70°F even in January, so lettuce and spinach may bolt faster than in cooler zones. Choose bolt-resistant varieties and plan succession sows every two weeks.
