Charlotte, NC Vegetable Planting Calendar
Here are planting dates for 26 vegetables in Charlotte, for the 2027 season, based on 1991–2020 normals. We start from the 32°F frost odds at Charlotte Douglas Airport (7.1 mi W) 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 Charlotte's own NOAA frost dates. North Carolina extension guidance may differ, so check it too.
Frost anchors: typical last frost Mar 30 (50%), balanced Apr 5 (30%), safe Apr 14 (10%); typical first frost Nov 3. Station Charlotte Douglas Airport (USW00013881), confidence High. USDA zone 8a (2023). Charlotte 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 30, 50% risk), balanced = Apr 5 (30%), safe = Apr 14 (10%). For hardy crops the cell shows the CSU “as early as” window.

A soil thermometer helps here. CSU recommends checking soil temperature at 4 inches (6 inches for beans) before sowing. NOAA doesn't publish soil-temperature normals, so instead of a date, each crop shows CSU's minimum soil temperature.
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 3) | By (early first frost Oct 22) |
|---|---|---|---|---|
| Peas | sow | 79 | Aug 16 | Aug 4 |
| Lettuce (leaf) | sow | 74 | Aug 21 | Aug 9 |

Crop-by-crop notes
When to plant tomatoes in Charlotte
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 Charlotte at about Apr 13, but the average nightly low at Charlotte Douglas Airport isn't above 52°F until Apr 26, so our dates start there: about Apr 26 (typical), Apr 26 (balanced) or Apr 28 (safer 10% date). Start seeds indoors Mar 8–22, 5–7 weeks before transplanting on Apr 26. CSU notes that nights under 55°F hurt fruit set. The normal low at Charlotte Douglas Airport climbs to 55°F on May 6. CSU's typical time from transplant to harvest for tomato plants is 65 days. Set out on Apr 26, they would start producing around Jun 30, 126 days before the typical first frost (Nov 3).
When to plant peppers in Charlotte
Very tender crop. CSU Extension's rule is 2+ weeks after the average last frost, which puts peppers outside around Apr 13 (typical date), Apr 19 (balanced) or Apr 28 (safer 10% date). Start seeds indoors Feb 22 – Mar 8, 6–8 weeks ahead of transplanting on Apr 19. Below 55°F at night, fruit set suffers (CSU). At Charlotte Douglas Airport, the normal low reaches 55°F on May 6. Set out on Apr 19, pepper plants would start producing around Jun 28, based on CSU's typical 70 days from transplant to harvest. That leaves 128 days before the typical first frost (Nov 3).
When to plant potatoes in Charlotte
Semi-hardy crop. CSU says potatoes can be planted as early as 0–2 weeks before the average last frost, in soil of at least 45°F. In Charlotte, that's roughly Mar 16–30 going by the typical date, or Mar 31 – Apr 14 going by the safer date.
When to plant onions (dry, from sets) in Charlotte
Hardy crop. CSU says onions (dry, from sets) can go in as early as 2–4 weeks before the average last frost: roughly Mar 2–16 in Charlotte using the typical date, or Mar 17–31 using the safer one. Wait until the soil can be worked and is at least 35°F.
When to plant peas in Charlotte
Hardy crop. Per CSU, peas can be planted as early as 2–4 weeks before the average last frost, as long as the soil is workable and at least 40°F. For Charlotte, that works out to roughly Mar 2–16 (typical date) or Mar 17–31 (safer date). For fall, count back 79 days from the first-frost date. That means sowing by Aug 16, or by Aug 4 to be safe.
When to plant lettuce (leaf) in Charlotte
Hardy crop. CSU says lettuce (leaf) 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 Charlotte, that's roughly Mar 2–16 going by the typical date, or Mar 17–31 going by the safer date. For fall, sow by Aug 21 (Aug 9 to be safe), which is 74 days before the first-frost date.
When to plant carrots in Charlotte
Semi-hardy crop. Per CSU, carrots can go in as early as 0–2 weeks before the average last frost: roughly Mar 16–30 in Charlotte (typical date) or Mar 31 – Apr 14 (safer date). The soil should be at least 40°F. For a fall crop, sow by Aug 11, or by Jul 30 to be safe. That's 84 days back from the first-frost date.
When to plant beans (snap) in Charlotte
Tender crop. CSU's timing for beans (snap) is around the average last frost, which is about Mar 30 in Charlotte. For only a 1-in-10 chance of a later 32°F night, hold off until Apr 14. Seeds want soil at 55°F or warmer. For fall, count back 88 days from the first-frost date. That means sowing by Aug 7, or by Jul 26 to be safe.
When to plant summer squash in Charlotte
Tender crop. CSU says to sow summer squash around the average last frost, about Mar 30 in Charlotte. If you want only a 1-in-10 chance of a later 32°F night, wait until Apr 14. Seeds need soil of at least 60°F. For fall, sow by Aug 17 (Aug 5 to be safe), which is 78 days before the first-frost date.
When to plant broccoli in Charlotte
Hardy crop. CSU says broccoli can go in as early as 2–4 weeks before the average last frost: roughly Mar 2–16 in Charlotte using the typical date, or Mar 17–31 using the safer one. Wait until the soil can be worked and is at least 40°F. Using CSU's typical 65 days from transplant to harvest, broccoli plants set out on Mar 8 would start producing around May 12. That's 175 days before the typical first frost (Nov 3). For a fall harvest of broccoli, get transplants in the ground by Aug 16 (UNL Extension count-back from the typical first frost, Nov 3, with CSU's 65 days from transplant to harvest). To raise your own, sow seeds Jun 28 – Jul 12, 5–7 weeks ahead (CSU).
When to plant cabbage in Charlotte
Hardy crop. CSU says cabbage can go in as early as 2–4 weeks before the average last frost: roughly Mar 2–16 in Charlotte using the typical date, or Mar 17–31 using the safer one. Wait until the soil can be worked and is at least 40°F. Set out on Mar 8, cabbage plants would start producing around Jun 1, based on CSU's typical 85 days from transplant to harvest. That leaves 155 days before the typical first frost (Nov 3). Fall cabbage: set transplants out by Jul 27. The date counts back from the typical first frost (Nov 3) by UNL Extension's method, using CSU's 85 days from transplant to harvest. Home-grown transplants need seeds started Jun 8–22 (CSU: 5–7 weeks).
When to plant cauliflower in Charlotte
Semi-hardy crop. CSU allows planting cauliflower as early as 0–2 weeks before the average last frost, in soil at 40°F or warmer. For Charlotte, that's roughly Mar 16–30 by the typical date or Mar 31 – Apr 14 by the safer date.

FAQ
When should I start seeds indoors in Charlotte?
Tomatoes: Mar 8–22. Peppers: Feb 22 – Mar 8. Both windows count back from a balanced (30%-risk) transplant date using CSU's transplant ages.
When should I plant tomatoes outside in Charlotte?
About Apr 26 at the earliest, Apr 26 as a balanced choice, or Apr 28 to be safe. CSU wants tomatoes out 2+ weeks after the average last frost (that rule alone gives about Apr 13 here) and nights above 52°F. At Charlotte Douglas Airport, the average nightly low first rises above 52°F on Apr 26, so the earliest date starts there.
What can I plant in Charlotte in the fall?
Counting back from the typical first frost (Nov 3) with UNL Extension's method: peas by Aug 16; lettuce (leaf) by Aug 21; carrots by Aug 11; beans (snap) by Aug 7; summer squash by Aug 17; broccoli by Aug 16 (transplants); cabbage by Jul 27 (transplants); kohlrabi by Aug 31; green onions by Aug 21; radishes by Sep 20; spinach by Sep 10; turnips by Aug 31; beets by Aug 21; swiss chard by Aug 21; cucumbers by Aug 12.
