Texas Fall Vegetable Garden

Texas fall vegetable gardening is productive in ways most northern gardeners don't expect. While summer heat (consistently above 95°F in most of the state) limits summer production to a narrow window, the fall season from August through December offers excellent conditions for both warm-season and.

Texas fall vegetable gardening is productive in ways most northern gardeners don't expect. While summer heat (consistently above 95°F in most of the state) limits summer production to a narrow window, the fall season from August through December offers excellent conditions for both warm-season and cool-season crops.

Per Texas A&M AgriLife Extension, fall planting is often more productive than spring planting in most of Texas because temperatures moderate reliably from September onward, fall insects are typically less severe than spring/summer populations, and many cool-season crops overwinter in zones 8–9.

Fall Warm-Season Crops

Tomatoes — the most important fall crop

North TX: Transplant August 1–10 | Central TX: Transplant August 10–20 | South TX: Transplant August 20–September 1

Per Texas A&M AgriLife Extension, fall tomatoes are planted from transplants in early-to-mid August to allow the plants to establish before the intense heat breaks and to produce fruit in September–October before first frost. Short-season varieties are critical:

• 'Celebrity' (70 days) — excellent disease resistance for Texas conditions
• 'Sweet 100' or 'Sweet Million' (cherry, 60 days) — faster maturity
• 'Heatmaster' — bred for Texas summer/fall heat

Do not direct-seed fall tomatoes — transplants give you 3–4 weeks head start, which is critical for maturity before frost.

Peppers

North TX: Plant August 1 | Central/South TX: Plant August 1–15

Per Texas A&M AgriLife Extension, fall peppers planted in early August often produce their best crop in September–October as temperatures moderate. They tolerate Texas fall heat better than tomatoes. Banana peppers, jalapeños, and cayenne are especially productive in Texas fall conditions.

Southern Peas (Cowpeas)

Statewide: Plant August 1–September 1

Per Texas A&M AgriLife Extension, Southern peas (Vigna unguiculata — blackeye peas, purple hull peas) are warm-season crops that thrive in Texas's late-summer heat. Direct sow in early August, harvest in September. Extremely heat-tolerant. 'Pinkeye Purple Hull' and 'Mississippi Cream' are common Texas varieties.

Summer Squash (Second Planting)

Statewide: Plant August 1–15

Per Texas A&M AgriLife Extension, a second planting of summer squash in early August produces well in September–October in Texas. The first summer planting typically declines from heat, drought stress, and squash bugs in July; a fresh planting in August avoids peak insect pressure. Direct sow when soil is still above 65°F.

Fall Cool-Season Crops

Broccoli and Cabbage

North TX: Transplant September 15–October 1 | Central TX: Transplant October 1–15 | South TX: Transplant October 15–November 1

Per Texas A&M AgriLife Extension, fall broccoli and cabbage are primary Texas cool-season crops. Start transplants indoors 4–6 weeks before the outdoor transplant date or purchase transplants from garden centers in September. 'Packman' and 'Marathon' are standard fall broccoli varieties for Texas.

Root Vegetables

Statewide: Direct sow September 15–November (varies by zone)

Per Texas A&M AgriLife Extension:

• Carrots: Direct sow when soil cools below 80°F. 'Danvers 126', 'Chantenay Red Core', 'Nantes'.
• Beets: September 15–November 1. 'Detroit Dark Red', 'Chioggia'.
• Turnips: September–October. Quick-maturing (45 days); can be succession-sown.
• Radishes: Sow every 2 weeks September–November.

Greens

Per Texas A&M AgriLife Extension, Texas is one of the best states for cool-season greens because the long mild fall extends the harvest:

• Spinach: Direct sow September–November; overwintering possible in zones 8–9
• Kale: Plant September–November; survives winter in zones 7b–9
• Collards: Plant September–November; a Texas fall staple
• Lettuce: Direct sow or transplant September–November
• Swiss chard: September–November; tolerates light frost

Texas Soil Preparation for Fall

Per Texas A&M AgriLife Extension, Texas soils vary dramatically:

• Black clay (Blackland Prairie): Work when slightly moist, not wet; needs compost for drainage
• Sandy loam (East Texas, Sandy areas): Needs compost for moisture retention and nutrients
• Calcareous limestone (Hill Country): pH 7.5–8.5; amend with sulfur and compost; choose alkaline-tolerant varieties
• Coastal clay (Gulf Coast): Heavy drainage problems; raised beds recommended

Per Texas A&M, add 3–4 inches of compost before every planting and incorporate to 6–8 inches. Texas soils are highly variable but consistently benefit from organic matter additions.

Frequently Asked Questions

When do I plant garlic in Texas? Per Texas A&M AgriLife Extension, garlic is planted in October–November in most Texas zones, 2–3 weeks before the first frost in North Texas, or November–December in South Texas. Softneck varieties (Artichoke group, Silverskin group) perform better than hardneck types in Texas's mild winters, which may not provide sufficient chilling for hardneck types to bulb properly.

Can I grow tomatoes year-round in South Texas? Per Texas A&M AgriLife Extension, in the Rio Grande Valley (zone 9b–10a), tomatoes can be grown almost year-round with the exception of the hottest summer months (July–August). Two main planting windows: February–March for spring harvest, and August–September for fall harvest extending into December. Heat-tolerant cultivars like 'Heatmaster' and 'Solar Fire' are important.

Which Texas pests are specific to the fall garden? Per Texas A&M AgriLife Extension, the most significant fall garden pests in Texas include: aphids on brassicas (increasing in cooler fall weather), cabbage loopers and imported cabbageworm, whiteflies on warm-season fall crops, and thrips. Fall gardens often have lower overall pest pressure than summer plantings because many pest populations decline with cooling temperatures.
