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 first fall frost arrives between October 23 (8a) and October 29 (8b), so the stretch from a September transplant date is short, depending on subzone. Summer heat breaks late here: resist sowing cool-season seeds until soil temperatures fall below 80°F.

Zone 8a: First Fall Frost October 23

Start broccoli and cabbage transplants indoors in early August. Move them outside when soil temps drop below 80°F, typically in early to mid-September in most Zone 8a locations. Direct sow lettuce, spinach, arugula, and radishes starting in mid-September. Carrots and beets can go in as late as early October for harvest as young roots before the first fall frost. Garlic planting runs from mid-October through early November.

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

Zone 8b: First Fall Frost October 29

The extra 15 frost-free days 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 early September. 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 in early to mid-August. Tomatoes set after early September 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 early to mid-October 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 mid-October 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.
