Fort Worth, TX Vegetable Planting Calendar
Here are planting dates for 26 vegetables in Fort Worth, for the 2027 season, based on 1991–2020 normals. We start from the 32°F frost odds at Fort Worth Meacham Field NAAF (2.4 mi N) and apply CSU Extension timing rules, each listed below with its source.
These are Colorado State University Extension (spring) and University of Nebraska–Lincoln Extension (fall) timing rules, applied to Fort Worth's own NOAA frost dates. Texas extension guidance may differ, so check it too.
Frost anchors: typical last frost Mar 5 (50%), balanced Mar 12 (30%), safe Mar 25 (10%); typical first frost Nov 24. Station Fort Worth Meacham Field NAAF (USW00093904), confidence Medium. USDA zone 8b (2023). Fort Worth frost dates & growing zone.

Spring planting dates
“Plant out” means transplanting for crops started indoors and sowing or planting directly in the garden for the others. Each column applies CSU Extension's timing rule to a different last-frost anchor: aggressive = typical date (Mar 5, 50% risk), balanced = Mar 12 (30%), safe = Mar 25 (10%). For hardy crops the cell shows the CSU “as early as” window.

Before sowing, check the soil too. CSU recommends taking its temperature at 4 inches (6 inches for beans). Since NOAA publishes no soil-temperature normals, we give CSU's minimum soil temperature for each crop rather than a date.
Fall planting dates
Latest dates for a fall harvest, using the University of Nebraska–Lincoln Extension count-back formula: days to harvest (CSU) + 14-day fall factor + 14-day frost-tender factor for frost-sensitive crops, counted back from the first-frost date. For transplanted crops (CSU days are from transplant) the result is the latest transplant date; seeds go in CSU's transplant-age weeks earlier. We add no harvest period, so these dates give you a first harvest by the first frost, not a long harvest.
| Crop | How | Days counted back | By (typical first frost Nov 24) | By (early first frost Nov 3) |
|---|---|---|---|---|
| Peas | sow | 79 | Sep 6 | Aug 16 |
| Lettuce (leaf) | sow | 74 | Sep 11 | Aug 21 |

Crop-by-crop notes
When to plant tomatoes in Fort Worth
Very tender crop. CSU Extension says to transplant tomatoes at least 2 weeks after the average last frost, with nights above 52°F. The frost rule alone would put Fort Worth at about Mar 19, but the average nightly low at Fort Worth Meacham Field NAAF isn't above 52°F until Mar 27, so our dates start there: about Mar 27 (typical), Mar 27 (balanced) or Apr 8 (safer 10% date). Start seeds indoors Feb 6–20, 5–7 weeks before transplanting on Mar 27. Below 55°F at night, fruit set suffers (CSU). At Fort Worth Meacham Field NAAF, the normal low reaches 55°F on Apr 7. Set out on Mar 27, tomato plants would start producing around May 31, based on CSU's typical 65 days from transplant to harvest. That leaves 177 days before the typical first frost (Nov 24).
When to plant peppers in Fort Worth
Very tender crop. Following CSU Extension's rule (2+ weeks after the average last frost), set peppers out around Mar 19 with the typical date, Mar 26 for a balanced choice, or Apr 8 with the safer 10% date. Sow seeds indoors Jan 29 – Feb 12, 6–8 weeks before transplanting on Mar 26. Below 55°F at night, fruit set suffers (CSU). At Fort Worth Meacham Field NAAF, the normal low reaches 55°F on Apr 7. Using CSU's typical 70 days from transplant to harvest, pepper plants set out on Mar 26 would start producing around Jun 4. That's 173 days before the typical first frost (Nov 24).
When to plant potatoes in Fort Worth
Semi-hardy crop. CSU allows planting potatoes as early as 0–2 weeks before the average last frost, in soil at 45°F or warmer. For Fort Worth, that's roughly Feb 19 – Mar 5 by the typical date or Mar 11–25 by the safer date.
When to plant onions (dry, from sets) in Fort Worth
Hardy crop. CSU says onions (dry, from sets) can go in as early as 2–4 weeks before the average last frost, once the soil can be worked and is at least 35°F. In Fort Worth, that's roughly Feb 5–19 going by the typical date, or Feb 25 – Mar 11 going by the safer date.

FAQ
When should I start seeds indoors in Fort Worth?
Tomatoes: Feb 6–20. Peppers: Jan 29 – Feb 12. Both windows count back from a balanced (30%-risk) transplant date using CSU's transplant ages.
When should I plant tomatoes outside in Fort Worth?
CSU Extension's rules for tomatoes are 2+ weeks after the average last frost and nights above 52°F. The frost rule alone would allow about Mar 19 here, but the average nightly low at Fort Worth Meacham Field NAAF isn't above 52°F until Mar 27. With both rules, the dates are about Mar 27 at the earliest, Mar 27 as a balanced choice, or Apr 8 to be safe.
What can I plant in Fort Worth in the fall?
These sowing deadlines count back from the typical first frost (Nov 24) using UNL Extension's method: peas by Sep 6; lettuce (leaf) by Sep 11; carrots by Sep 1; beans (snap) by Aug 28; summer squash by Sep 7; broccoli by Sep 6 (transplants); cabbage by Aug 17 (transplants); kohlrabi by Sep 21; green onions by Sep 11; radishes by Oct 11; spinach by Oct 1; turnips by Sep 21; beets by Sep 11; swiss chard by Sep 11; cucumbers by Sep 2.
